The RK kits are easy to get the squat out of. The biggest problem with most current TJ setups is the axle loading and unloading "hop" they get. I took a new friend out yesterday to RAM to shake down his setup and see where we needed to go with it. He has a rubicon express 5.5 longarm, procomp adjustable piggyback shocks and has been bastardized by a ton of different people over the years. He is running a 37inch radial IROK tire. Friday night I gave it a good inspection and centered his axles. Had to actually cut his trackbar threads to get more adjustment just to get the damn front axle to center, was a total mess. we set his wheelbase at 94.5 inches, squared everything up and decided to go with it.

So, the story, his jeep is great on ledges and seems to now drive on the street better. We are going to lower it by an inch, go to a 4link rear and ditch the rubicon express radius arms..

The problem is the thing just hops like a pissed off monkey if it gets in any type of traction loss. We where messing around on a few 3 ledge waterfall type climbs at the park. I would rate one of them an 8 and one a solid 6. there was a buggy that got denied on the 8. It took a little work but I made it up, THE only reason I did is I get ZERO hop out of my setup and can let my tires spin and find the traction they need. Dude with the buggy was very confused, but realized his setup was wrong and he would get axle hop something fierce.

Moral to all this is a well thought out setup is splitting hairs and taking your time. I will update on the TJ after I get my dirty little hands on it again. My friend is all in so I am unsure of what I am going to do with it. I like his crossmember and will build off of that for the 4link rear. I may go with the synergy truss on this jeep. From a blank canvas I choose the RK stuff hands down, only because I have spend a ton of time with it.

p.s. I am no longer on a four link rear, I am back to a factoryish rear setup unitl I get my 3link stuff sorted out.
I like the synergy truss, nice and snug to the housing. Think I am going to be hacking mine so that I can set the links lower. I'm trying to keep my lift as low as possible and it's getting a little tight on top. I know that I will be swearing a blue streak at some point: "OK, idiot, now exactly how did you think you were going to get a wrench on that nut?" Oh, well

Oh yeah, now I remember what I was going to ask, when you tweak the RC setup, how much adjustment can you get on the anti squat percentage?

on the stock components roughly have a +/- 20% if you modify the truss you can get that to a -20% to a +40% I think it is in the area of 65% antisquat if you just throw it on. I would have to look at my notes, those are in my toolbox at work, so do not quote me as of yet.. I have never taken this set up over 4 inches of lift FYI. I think all is out the window over 4inches of lift. I usually wind up in the 3.5 inch range. highlined and if needed a 1inch body lift puts it on 35-37s depending.

That's better than I expected, I can see why you would use the kit. Since, if I remember right the kit uses stock lower links and all the frame link mounts 3.5 would be the realistic upper limit on spring lift. I assume all adjustment is on the truss brackets. 65% isn't a bad starting point, especially if it is driven on the street. Taking it to 85% or 105% would be all I could see for rocks, that is all I'm planning for at this point. If I am missing something here please let me know while I'm still in the planning stages

you have choices, I usually go with the long arm set ups. Using the factory length links and pickup points is kind of limiting TJ links are just to short

Yeah, that's why I'm building from scratch. Current layout has 24" horizontal links on a bolt on cross member. Heavy lower links cuz they will get a lot of abuse if I start chasing you up waterfalls

Yup, that's an axle all right. First thing you need to do is strip everything off the tubes and plug the brake connections. Hope it wasn't a leaf spring setup. Those cast leaf mounts are a bitch to cut off...

Well I have decided to stick with my original plan and do a straight swap with the truss system that I posted earlier TJ 8.8 Swap Kit with Truss. If later i decide to go 4 link the truss can be modified to accept it. so there you have it. I just ordered the truss. I hope to have this upgrade done by the end of April so I can enjoy it this summer. I truly do appreciate and respect all of your input but I think this will do fine for what I need at the moment. And later I may kick myself in the rear but for now I'm smiling...

Your rig, your choice

I think you'll end up with a good setup out of it and I hope it goes well
