- Start date
Ok, so I want to make sure I have this right before making any changes this weekend. My current setup is bilsteins all around set at .85 in the front and and a 2" spacer on the rear with stock springs.I want to add fj springs, shout I get rid of the 2" spacer in the rear and set the fronts to 1.75? Is it easy to switch from .85 to 1.75? Anything else I need to know or do?I have a 2006 sport edition v8 2wd.Thanks
I posted this in tue fj spring sticky but haven't heard back yet from anyone.

Ok, so I'm pretty settled on the TT Ultimate kit now. Are people actually getting only 2" of lift out of the Superflex coils? That's all I want and I know Toytec is sometimes a little conservative when listing lift amounts. I tried searching but couldn't find anything too conclusive.

Bilstein setting with rear fj coils only
Ark- I've been searching these forums ever since I bought by 4runner back in November, I just purchased some 5100's and plan on putting them on in the next week or two. I'm sure someone has done the exact setup that I'm going to do but I haven't been able to find anything. I've got an 05 sr5 V6. I bought some FJ springs, REAR only, and I am going to put the 5100's all around. I'm looking to see if anyone has done the rear springs only and then set the fronts at the 1.75 setting. I would like to know what the measurements are with this set up and what people's opinions are. I do very minor towing(whitewater raft) which isn't any more than 1500lbs total(raft/frame/cooler/trailer). I don't want to have any negative rake when the trailer is hooked up so if I have .5-1 inch of rake when the trailer isn't hooked up that is ok, but I do want it as level as possible. I know I would be safe with the .85 setting but I just don't think that will be enough lift, especially since I'm not putting the fj springs on the front.
Any advice/input/opinions are welcome.
I'm loving this forum in general by the way, I'm learning a lot about my 4runner

Could it be Truxx? I feel like I've heard of that before
Just got a quote from a shop to install my lift (fj springs all around and 5100 from and icon rears) He wants $500. I'm confident I could do it myself but you know how that goes. Once you talk to someone they scare you with all the what if's.... Anyone else pay to get it done and is that a fair price?
Yes actually I think that is it.

Ok I'm looking at a complete FJ set up paired with Billie 5100's on my 04. I realized that in order to get a leveled stance people are putting a spacer in the rear. I was wondering if I could just achieve the leveled stance with a toytec superflex coil instead of using the poly spacer? I don't know if this will lift the ass end up too much, because I'm really going after leveled. I also really really don't want a bro stance.
Thanks in advance.

Ok.....so I've been extremely busy over the last several weeks and have let many things here go unanswered. I'm sure by now most of you have found your answer and some have chimed in here to help. I'll go ahead and throw in my opinion and try to catch all the questions.
As stated 3" is the max. Is your spacer 1" thick or 1/2" thick (1" total lift)? I have concerns about using a spacer with the 5100's. The 5100's are longer than OEM and with the spacer you're pushing the assembly down allowing even more droop, enough that you can be out of the "safe" operating range. I'd personally feel better ditching the spacer and going with the 5100's at the highest notch. If you're 100% street driving it's not as big of an issue as you'll likely never flex the front all the way, but with some off road use I could see it causing accelerated wear.
Although I've never had them, I've heard great things about the Superflex coils. On paper, they are perfect for a stock weight vehicle, little stiffer than stock but not enough to be harsh. I think the Superflex's with air bags would be a great setup. See this thread for more info, and note the link in the last post, it contains the correct part number to be used with the Superflex coils.

Never heard of them, but looks very similar to the Icon's. I'll have to do a little digging to see what I can find out about these.
You'll get ~1" in the front and 1/2" in the rear with the FJ coils. I think if you are going to the 1.75" setting you would want to keep the rear spacer installed, otherwise you'll be high in the front.
As noted above, I've never actually ran the Superflex coils so I can't say for certain, but I"m pretty sure folks are getting right at 2" lift with those coils. Remember actual measurements will vary due to how much the stock coils have sagged, so if you're have sagged a good bit then you very well could see over 2".
I think you'd be fine with the 1.75" setting on the front. If it sags too much with the trailer, then I'd consider adding air bags to the rear so you can compensate when towing. Airlift or Firestone air bags will run under $100 and are pretty easy to install.
With some trimming and wheel spacers, you could fit 285/70/17's. The aftermarket bumpers will help clear the 285's more easily. You could also do something like a 275/70/17 which is a little smaller but wouldn't require much trimming or wheel spacers.
I've not found very much info on this so I've been hesitant to add it to the list. Ironman has a great reputation from what I've gathered, but I haven't found any real feedback on it so I've stuck with the more common vendors for this thread. I will make note of this and see if I can find some info to add to the OP.
As noted, it's most like a Truxx (now called Traxda). Their kit is 3" front and 1.25" rear. Not sure what they're charging you, but there are much better options IMO. The Daystar 2.5/1.5 runs ~$150 and the Toytec 3/2 is $240. Both high quality kits and much cheaper than the Truxx (retail is $417).
I think that's insane. It's a 4 hour job. The only issue is going to be rust, some folks up north run into install issues and it causes problems. That would be my only concern, otherwise the install is straightforward.
Yes you can. If you have a v6 you can use the 1.75" setting and get ~2.75" lift, or if you have a v8 you can use the 2.5" setting and get ~3" lift. In the rear you'd get 2", so this would take out some of the rake.

Thanks for the reply....my spacer is 1in thick so mathematically my lift up front is 3.75in but I feel like the stock springs have sagged abit so i'm probably closer to 3.25in. Alignment has been out for the past year since my LCA alignment cams are seized and I haven't bothered fixing them yet since my tires are on there last legs anyways.
I haven't had time to do any offroading lately, I mean it sees the odd field or skidoo trail but no serious flexing or anything. I think I will do what you suggested and remove the spacer. Wish I could find some FJ coils but they seem to be hard to come by these days.

That's ridiculous. See how the bolts on everything look and if they don't seem to be seized by rust you should be fine doing it yourself. A fair price to get it done would be about $200. $500 is way out there.

Yea, I'd be concerned with the amount of droop you're getting out of that setup. If you're unable to find FJ coils, consider running Tacoma front coils. I'd be they'd be much easier to find and IMO are just as good if not better than the FJ coils.

Yeah I agree. When he told me i chuckled and was offended. This was suppose to be a "hook up" deal because one of my good friends has known him forever. Now that I have to do my axles that i just ordered from CVJ. I'll just blast everything that has rust on it with PB and I'm also planning on going to a Toyota Dealership and buy all new bolts/nuts in anticipation of breaking some.

if anyone has any input, im curious as to which coil would be best. i use my 4runner as a daily driver, but wheel it, and it also tows a trailer once or twice a month that has substantial weight, what would be better, icon's or superflexes?

Yeah when I replaced the suspension on my old '01 I had trouble getting the front assembly in. The back went in without a hitch but I couldn't get all of the bolts off on the front and I don't have an impact gun. I took it to a shop and they did the fronts for somewhere around 80-100 bucks. Whoever told you that it would be $500 is either testing you to see if you're stupid or on crack.:jaw:

Unless you're planning to add constant weight to the rig, I'd say the Superflexes with air bags. Air bag setups are cheap, easy to use, and give the added support when needed. Trying to get a coil heavy enough to prevent rear end sag with "substantial" weight will offer a stiff ride at other times. Adding air bags gives you the best of both worlds. See this post for a little info and the correct part number to be used with the Superflex coils.
