What Sliders Can you run with KDSS?

I installed Demello Bolt On Hybrid Sliders last week on my 2014 trail w/ KDSS.

They are built well and the powder coat was in good condition (I picked them up myself to save on shipping and they had them in stock).

It took ~3.5 hours solo without power tools to do the install. The passenger side was straight forward (I laid down some spare cardboard to prevent dinging up the hardware and keep myself off my dirty driveway).
1) Unbolt the brake line brackets
2) Bolt up the passenger side slider
3) Pat self on back
The driver side is a different beast but whatever you do, don't use a hammer and don't use a crowbar!
1) Unbolt the brake line & KDSS hard line brackets
2) Unbolt the two skid plates for KDSS (one for the pressurized main unit, and one for where the lines cross under the frame member - 2 bolts each)
***Note that the KDSS unit is attached to a sheet-metal bracket via two bolts and that the bracket is bolted to the frame by two bolts. The sheet-metal bracket has two tabs that protrude into the frame rail (the lower one has a bent up tang on the end, while the upper is straight).
3) Disconnect the electrical connector to the KDSS unit.
4) Unbolt the two bolts that attach the KDSS bracket to the frame (leave the KDSS attached to the bracket)
5) There is a bolt that goes through the KDSS unit directly into the frame. Unfortunately there are a lot of fittings on the KDSS unit and you don't want to mess with the wrong fitting. Partially unscrew this bolt to clear the slider thickness, but don't fully back it out (USE CAUTION and I believe the bolt is the one above the electrical connector in the upper right[aft] corner)
6) You should have some freedom to slightly move the KDSS unit now. Bend the two tabs that engage the frame from the bracket to free the KDSS unit (still attached by the one bolt).
7) Bolt the slider up (I used some spare wood and the vehicle jack to act as a second hand while carefully aligning / positioning this side)
8) Bolt up the KDSS unit, reconnect electrical, and bolt up the skid plates.
9) BEER

An additional note: The brake brackets and KDSS bracket have non threaded features that engage the frame (brake brackets are for anti-rotation, KDSS bracket is for factory install... this is all just my opinion / speculation). The Demello sliders do not have holes for these tangs so you just have to bend them / ignore them.

Good luck in your search.

(Disclaimer: do not follow the above instructions/ideas, and let's not talk about screws vs. bolts).

Thanks for these great installation instructions. I was thrown for a loop on trying to pull the KDSS system away from the frame on the driver side until I found this thread. I removed the two bolts connected to the KDSS bracket but couldn't figure out why it was still not moving until I read #5 in your step-by-step instructions. Until you pointed out the bolt in the upper right corner near the electrical connector that needed to be removed, I was getting pissed. I never knew to look for that. Actually the bolt needs to be completely un-threaded from the hole to allow the sliders' backing plate to slide up. I thought you were saying to loosen the bolt but not remove it from the hole. Obviously, you can't slide the backing plate past that section if the bolt is still in the hole. Once I removed the bolt, the slider plate slid right up using a jack. I couldn't fully remove the bolt even if I tried since it was hitting the body. Anyway, thanks again! Not having instructions from Demello makes this a chore.
 
I have some pelfreybilt sliders coming in for my 16 w/kdss... gotta start looking for pics of those driver's side install...
 
I got me the first set of demello's dominatorz for the 5th gen. They r sweet and install was as posted in above threads . Sorry I don't kno how to upload pics. But they were real popular for the FJ crowd ! Thanx to Daniel of demello offroad , great customer service !

RCI Metalworks just released sliders for 5th-gens and has models for both KDSS and non-KDSS. I'm in the process of ordering mine now, but when I initially asked Josh about the separate KDSS sliders, this is what he said:

"As for the sliders, it is not a website error, these are available for both KDSS and NON KDSS 4Runners. Due to the KDSS system on the drivers side, we designed a custom frame plate that is 2-pieces and completely avoids the central KDSS unit and slides in underneath the rear of the KDSS lines. This still allows for 3 gusseted legs to the slider.

We can powdercoat the sliders for you. The cost is $150."

I just installed these.

Was pretty simple really. The KDSS lines are a slight annoyance to deal with, but really the tough part for me was getting the front frame piece in and then keeping it there while snaking the rear piece behind the lines. Once it was up, it was no big deal.

Had a few annoying bolts, one of which I could not get the supplied bolt in, due to length.

Outside of that though, it was pretty easy. Took me 2.5 hours or so, using real cheap shitty hand tools, and the help of my girlfriend.
 
Seems like a lot of extra weight and metal that has no structural value here. The white area could all be eliminated without any difference in strength. I'm guessing the idea was to eliminate the need for a jig to align all the holes, but there's still a 2 plate system on each side - so you still need a jig. The mounting plates look like 3/8" or so plate - I'm sure they're very strong!

FWIW - I built my own and did my best to keep the weight to a minimum. Ultimately they're all going to hit the pinch weld when you land hard on them - because the frame just isn't all that rigid. So I engineered with that in mind. With a static lift they'll lift the vehicle without moving up into the body, but I don't think the frame can withstand a 2' drop onto any slider design without some structural members running across to the far frame rail. Integration with skid plates could offer a lot of additional strength by building a truss structure - while keeping weight in check. These are on my KDSS 4runner. If you're home building it's pretty easy to notch the front plate to fit around the KDSS stuff.

I will have to agree that these instructions were the best (and most accurate I found). It appears that there are differences with slider brands when it comes to KDSS. Some have a complete cutout for it and others don't. Demello only has a cutout for the KDSS lines running under the frame rail. Given this, in order to make it happen on the driver's side, the shield for KDSS pump and lines needs to be removed. The KDSS harness needs to be unplugged, and the bolt behind it removed. The tabs on the frame for the KDSS pumps needs to be cut/bent, then you can slide in the slider. It was easier to get the front part up, then slide forward to get into place.

I've had one issue and that's figuring it how to get the bolt into this hole and tightening it. I get the impression it is not used, but not sure as I can't get the lines far away enough or split them apart far enough.

All Pro/Trail Gear sliders with KDSS

I ordered my sliders through All-Pro, clearly stated in order I had the KDSS system. Sliders were delivered fairly quickly. I then proceeded to degrease with acetone, prime, and rattle can paint sliders. The driver side slider was not manufactured correctly by All-Pro/Trail Gear, their gussets were interfering with the rear KDSS lines, pulling them too far away from the frame. I called All-Pro, and after a few failed attempts to get some answers, finally was put in contact with their "tech" guy. He at first insisted the order was correct, said the pictures in their install directions link were from a fellow employees KDSS truck. The pictures in their directions were clearly different from what I had received. He promised to look into things further, two days later, still no reply from him or All-Pro. I had to contact him, again to plead my case. Eventually, he said the correct KDSS slider would be shipped out, "his guys" were supposed to contact me, of course they did not. No apology, after his assistance, but I did request a small refund for the time, materials related to the painting of the incorrectly sent driver side slider, as I would have to repeat the process of degreasing, primer, paint, and install once again . All-Pro/Trail Gear would not agree to my slight refund request, per sales manager Jess Juarez.
I believe All-Pro/Trail Gear has been banned from this forum, but stay away from All-Pro/Trail Gear, very unprofessional.
