How To: Lift Installation (on KDSS equipped vehicles)

You only need to deactivate KDSS if you're not going to support the sway bar pistons. If I recall from the FSM, the deactivation/reset process is not trivial. It's far easier to keep your key out of the ignition and sway bars suppported while performing the lift installation. That's what I did for my KDSS trail with Icon Stage 7. No lean.
 
Sooo....Toyota was a dead end. When I asked the questions about the deactivation/reactivation instructions in the Toyota Service Manual, the parts guy asked if I was talking about "...that 500, or 600, page book that costs $700 and was used by the mechanics in the back..." After going into "just smile and wave mode" I learned they no longer do any lifts (other than Bilstein TRD/Pro stuff - that might be changing from Bilstein to Fox at some point), and they refer all lifts to a local specialty shop. I have been to the shop before, and I actually spent some time with the mechanic who was installing a Stage 6 Icon kit on a 4Runner which belonged to one of the lead guys' wives. At the time I had not read the instructions on Icon's site, so I'm headed back to see what issues they've had and to find out a little more about what they do.

Now, on the Icon front. I ended up calling their tech department to inquire further. First, their instructions are not referring to just unbolting a few bolts; however, they also do not have specific KDSS instructions made by their people. They sent me - I'm not sure what to call it as I cannot in good conscience say it was instructions. Well, they sent me a short list with a diagram that appeared to be something "tweaked" by one/some of their customers (at the bottom it said they were not Icon's instructions but "...just a guide..."). Part of it said to "...bounce the vehicle till the left and right sides are level..." I wrote back to see if this was re-pressurizing the system, but I got no response. I actually found the PDF full instructions on this forum, and I confirmed what Icon sent me was a small part a section from the instructions of bleeding/re-pressurizing the full KDSS system. I also found on this forum suggestions on not to do this unless you have some extra cash to get your vehicle to Toyota to have them fix what you'd just done...

Dude, just do it the way described in this thread. Hundreds have done it no problem. Or not, and do it some other way. Good luck.

This.....follow the instructions and/or watch some videos on YouTube regarding this process and take your time. Remember, ratchet straps are your friend when reattaching the KDSS sway bar.

Funny thing, information. When dealing with something I've not done before I usually take at least a gander at the instructions. Some parts might appear funky some not so much, but it's at least a way to point you in the right direction. Not interested in being a lemming as it usually doesn't work out real well for them in the long run...

A forum is defined as "a place, meeting, or medium where ideas and views on a particular issue can be exchanged". I have questions based on things that are written down by the company I am thinking of using for lift products. If there is only one other person who has the same questions I have done my part in bringing up the topic for further discussion and maybe we might learn something in the process. You know there have been things done in the past, for quite a while, and other ways were found to accomplish the same task. I'm sure these instructions will get the job done, but I have no qualms about bringing up the questions I had.

Oh yeah, the Icon instructions also state that if their products are not installed correctly, and failure occurs, the warranty is null and void.

I'll keep doing it my way, thanks. It seems to have done me well through my over 50 years of life.

You're definitely over thinking this. You are the first person I have seen with questions about lifting with KDSS that wasn't extremely happy with having this how-to thread pointed out to them.
 
I think he is saying the instructions from ICON conflict a bit with this thread. Also.. this thread has at least 5 different potential twists on ways of doing it.

There is lots of confusion about what the most ideal method is, but either way you end up going... it's kind of hard to mess it up really bad (besides stripping out the LCA bolts). If you don't do that.. you are good.

KDSS is just one of those things that will have many different techniques and nobody knows or wants to say what the exact method is. Dealers will be of no help... most would not lift a truck with KDSS.

If it was me... I would first try to do the front without disconnecting the KDSS swaybar. I'm just not 100% sure if this is possible or not, but a few in this thread said it was. If you can do it that way... then you saved yourself a ton of frustration.

The rear is easy.. but will require the swaybar to come off to get the springs in and out.. But it is not any type of struggle to get it back on.

I would not worry at all about holding the pistons in place or disabling the system in some way. Just disconnect your battery and get it back on level ground before connecting the batt back up and turning on the ignition. It should be fine.

The balancing procedure talked about... is very simple and easy to do. It is usually not required and does not seem to help much in the long run anyway. If you follow the instructions exactly as written... it is very simple. Just don't back out the bolts too much. They use a very confusing way of illustrating how far they need to come out. Read that at least 10 times and you won't screw it up. Basically subtract the measurement they give you from the bolt head (it will make sense when you read it with that hint in mind...)

The Factory Service Manual is available as a download for free. Look in the stickies... I'm pretty sure it is still there. It's not the best service manual I have seen, but it helps and having it for free is really nice and unusual.

I have lifted 4 KDSS equipped 5th Gens. This guide helped me with the first one I did and I continued using this procedure for the rest. I would not try to do the install without disconnecting the sway bar since it would be way more of a PITA, IMO. The biggest thing in the front is to attach the passenger side first, followed by the driver's side. Makes it wayyy easier.

I think I've done it 3 times, but I'm pretty sure I added a top hat spacer once without removing the swaybar. I just can't remember for sure. If the swaybar lets the LCA drop enough without a struggle.... if so that would be an extremely easy route to take and everyone has been wasting time wrestling with that bar.

I'm not arguing.. just clarifying that there is often another easier way and several people in this thread did say they did it this way. I will definitely try it next time. It might require that the LCA bolts be loosened up also, but if you are going to align it anyway after the lift... seems worth a quick try.

Not bashing this thread. It appears the original poster went to great lengths to document and detail how to get this done. I'm sure success has been experienced throughout the land. That's great. Just asking a question based on the instructions put forth by Icon and reporting my experiences in trying to get the answers. I was a little put off by the other person's "Dude" post, so I responded, and that is what it is.

I've done a full Icon lift before on my Tacoma, and even using experts I experienced an issue that took a few months to fix (and some aggravation I didn't need). That was accomplished by reaching out to others where we found how someone had fixed the exact issue I experienced. This is the first time on a new 4Runner, so I have the advantage of being able to take my time and hope I've learned from past experiences...

If I learn anything else I think might be helpful I'll pass it along.

This is a thread on one method to install a lift with KDSS. There are several ways, some good, some not so good. Again, do it this way or Icon way. Both will work. I will tell you though, I design high pressure hydraulic systems for a living and I would not do it Icon's way. If there is a way to keep from messing with a closed hydraulic system then I would do it. Less chance of screwing things up and learning a $2K lesson.

Yea, if you loosen the LCA bolts enough to allow a little extra movement to swing down, the cams won't even move. You do have to remove the LBJ bolts though. Realigning those can be a little difficult but not too bad.

This thread is a great tool. I feel if you use it as a guide and you have some basic knowledge of wrenching, you can DIY no problem.

my truck was jbstrd's 4th 'practice' subject and i can attest to how well this method worked. loosening the LCA bolts made things pretty easy and as he said, the cams didn't move in our case.
 
Installed cornfed leveling kit using the ratchet strap technique, 35 min per side, thanks for the great thread... bookmarked it for future lift.
 
I didn't see this thread until after I'd already finished my BOSS 2.5 install and was looking for KDSS torque specs. However, I can confirm most steps are accurate. My job in the front was made a bit easier as I was doing UCAs as well, so I didn't have to mess with the LCAs at all. Just popping the upper ball joint gave plenty of clearance to get the stock struts out. I do wish I'd have thought to remove the ABS wire bracket in the rear...would've made life a lot easier. Good write-up!
 
First off, I want to start by saying that a lot of the ideas below in my write up came right from this very forum; I merely just took all of those existing tips and further experimented to devise a simple and clear method for you guys to follow at home.

Unfortunately, I've read through way too many threads over the past few months to remember all of those whom provided valuable information, but tips from [MENTION=66316]1engineer[/MENTION], [MENTION=65614]Antman[/MENTION], [MENTION=8206]harper7[/MENTION], [MENTION=74569]SOcalTRAIL[/MENTION] and [MENTION=48991]sp8ball[/MENTION] were some of the most prominent ones that come to mind, so I must give credit where credit is due. Big thanks to all of you guys, and also to those whom I might have accidentally left out, sorry!

Now moving on to the lift process, I am not going to bother rewriting the book since Antman/Sp8Ball have already provided a well documented write up on how to do this process with non-KDSS vehicles; so I will just link you to it: http://www.toyota-4runner.org/5th-g...%92s-ideas-since-mid-2010-a-6.html#post754964

After you've had a chance to familiarize yourself with the above installation write up, let's get started. Obviously, the steps involving the standard sway bar do not apply to us KDSS folks; and of course you can install whatever suspension setup you want, just use a little imagination when putting in the new parts.

FRONT SUSPENSION

Step 1:
Before you raise your vehicle onto jack stands and take off the front wheels, remove the front skid. Now, with the vehicle still on the ground, locate the passenger side KDSS bracket (the bracket that is bolted to the LCA) and remove the two bolts; next, remove the two bolts from the driver side KDSS bracket.

Note, you should try your best to briskly remove each bolt because the KDSS sway bar has some tension on it and will want to push against the bracket while you are removing the bolts; so you probably want to avoid having the brackets pressing on the threads of the bolts for too long. It helps to have an impact wrench to quickly zip them off, though it is not required; personally, I just removed them by hand with a ratchet.

After the bolts are out, you will see that the KDSS piston slowly extends downwards and eventually stops. Now put the brackets and bolts aside for installation later. BTW, there's a left and a right, so don't mix it up; but if you do mix it up even after I told you not to, it's no big deal because they are marked "L" and "R", lol.

Step 2:
Go back to the Antman/Sp8Ball write up and follow steps 1 through 10.

Step 3:
After the vehicle is up on jack stands, you might want to consider supporting the KDSS piston if you plan to take forever and a day to finish the front end installation (like I did, lol). I am honestly not sure if it is bad or not to leave the KDSS piston in the fully extended position for an extended period of time, so what I did was place a jack under it before I closed up shop for the night, like so:


You will see that when you start jacking it up the piston will kind of resist, but rest assure it will compress just fine, so don't worry. I compressed the piston only about half way (roughly to the position where it would be with the sway bar connected and the tires on the ground). Note, I had it hanging completely downwards for a few hours at a time and all seems well afterwards; so if you work quickly, you probably don't even need to bother. I was just paranoid about leaving it like that over the course of 2-3 days and possibly busting a seal or something.

Another member here has informed me that the front KDSS piston boot actually popped off while he left it hanging down, so maybe it would be a great idea to support it with a jack once you remove the brackets.

Step 4:
This is kind of an optional (you will see why you might need to do this later), so while I recommend doing this step to make your life easier, it might not be entirely necessary. Locate your LCA adjustment cam bolts and mark all of them, like so:


You need to mark the plate's position because you want to get the alignment back to as close as possible afterwards. Now with the bolts marked, loosen each bolt a few turns (just enough for the LCA to rotate freely). This helps you with the next few steps, such as you not needing to pry the LCA downwards to get the shock out because the LCA will just drop freely.

Step 5:
Go back to the Antman/Sp8Ball write up and follow steps 11 through 17.

Step 6:
Okay, now for the optional stuff I was talking about earlier...if you are in a region that uses a lot road salt and/or otherwise prone to rust issues you might want to consider this. Remember those cam bolts I told you to mark earlier? Now go ahead and loosen them completely, support the LCA and take out all of the bolts and remove the LCA. However, easier said then done:


So now that you know the factory mid-skid plate prevents one of the bolts from coming out, go ahead and crawl under and remove that first before you do this step.

OR you can just leave the skid alone and rotate the cam bolt until it clears the skid and remove it that way, like another member here pointed below. Why didn't I think of that, lol.

Once you remove everything, you will see how much rust accumulates in there:


This was only after ONE winter for me, and not even 10k miles! I've read all to often on here about these very bolts being seized on for good and requiring lots of work to chop them off and replace the bushings, so this might be a valuable preventative maintenance step for some of you guys.

Step 7:
Clean up all the rust with a wire brush like so:


Then coat only the shaft of the bolt with your favorite anti-seize like so:


Remember to try to clean out the inner sleeves of the bushings as well and then reinstall the LCA and cam bolts loosely (loose enough so that the LCA can still swing up and down freely).

Step 8:
Go back to the Antman/Sp8Ball write up and follow steps 11 through 24, but DO NOT complete step 24 just yet! Just get the jack into position and ready for raising the LCA and stop.

Step 9:
Now depending on the shock/spring combo you are installing you might run into clearance issues between the KDSS pipes bolted to the frame and the coil spring when raising the shock back up into position, like so:


If you notice that the coil starts hitting the KDSS pipes, what you need to do rotate the adjustment cam bolts on the LCA so that the LCA extends outwards to you. This will give you just enough clearance to raise the shock back into position without interference, like so:


Step 10:
Go back to the Antman/Sp8Ball write up and follow steps 25 through 30. Note, I discovered a discrepancy in torque value between the FSM and the write up, so I went with the FSM. Not sure if Antman purposely wanted it a bit tighter or not. In particular, I am talking about the two bolts that hold the ball joint to the spindle, the FSM calls for 118 ft*lbf.

Step 11:
Now with that all done and the vehicle back down on the ground, here comes the fun part...reattaching the KDSS bar! This is how it should sit before you being this step:


This would be a good time to remove the rubber bushings and clean up the sway bar ends and the inside surface of the rubber bushings, like so:


Step 12:
Place a jack under the KDSS piston and slowly raise it up to align the passenger side bracket to the LCA. Once you get the bottom bolt hole to line up, loosely install the lower bolt first, like so:


Now play around with the jack height to get the upper tab to line up as close as possible, then shove a punch or screwdriver into the hole and pry the bracket into position and loosely install the upper bolt, like so:


Once bolt bolts are in, and you are sure you didn't cross thread them, tighten the bolts down only enough to leave about a 1/8" gap between the LCA and the bracket.

Step 13:
Now onto the driver side bracket, you basically repeat the same process by playing around with the jack height and position to align the bracket. This side you might need to have a helper to help you push the jack towards the vehicle in order to get the bracket close enough to start threading the bolts. At this point, the KDSS piston has a natural tendency to tilt outwards to the front of the vehicle making the gap between the bracket and the LCA huge. Start with the first bolt, like so:


Once that bolt is in and loosely threaded on, move onto the second one, like so:


After you get both bolts in, tighten them down only enough to leave a small gap like the passenger side. Now lower the jack completely and with the wheels still on the ground, then torque down the 4 KDSS bracket bolts to 55 ft*lbf.

Step 14:
Go under and align the adjustment cam bolts back to where you marked them, and torque those bolts to spec (129 ft*lbf). Afterwards, put back all of the skid plates you removed and stand back and admire your work because you're done!

Now for the obligatory shot of the front suspension looking all pretty and new:


I think this should be a pretty accurate description of what I did for the front suspension, but if I do remember any more steps, I will be sure to update the thread. Also if anyone notices and discrepancies please let me know so I can correct them!

Happy modding!! :cheers:

Is there a way to get this with updated photos or am I missing a Link?

Thanks for the write up, running through this in a week
