I just bought a RC 2 1/2 bb for my 2011 sport. I also got the rear track bar relocation bracket, brake line adjusters, front quick disco's and 2.2 shocks as well. I read the instructions provided and it doesnt mention anything about the front track bar. It does talk about installing the the sway bar links after the vehicle is back on the ground and I believe it says the same for the rear track bar(rear- hook it all back up but dont torque until on the ground.)
My question is this: Do I need to loosen the front track bar and upper and lower control arms also so that the vehicle properly seats to the new height after it is lowerd back to the ground? Then once its on the ground connect the disco's and tighten everything back up according to proper tourque specs. Like everyone else I would like to avoid the death wobble situation if at all possible....Not really familiar with the jeep as it is my first one. I have done a skyjacker lift on my chevy colorado prior to this vehicle but its suspension is set up differently.. Any answers or solutions would be greatly appriciated....Also i already have my tires and rims on the vehicle just waitin for time to do the lift.(285/75/r16's km2's on 7089 pro comps with 4.5 bs) Thanks

 

loosen everything up , sit the rig down on as level surface as possible, bounce up and down on the front end, then torque to spec.... If the steering wheel isn't centered loosen the draglink bolts and recenter the steering wheel. test drive it at different speeds. then re-check the torque on all of it. In my experiences , if you don't loosen everything up and sit the rig down with the weight on itself the bushings bind up and will eventually cause failure and problems. If you have adj. trackbars they will need adjusted also to recenter the axle.

 

Hey. thanks for the info. Ill do that and post pics when Im done. My budy just installed the same lift I have and got death wobble so Im a little concerned. Front track bar had a worn out bolt hole so a washer was welded in, ball joints are good,control arms and track bars were loose until vehicle got put down on the ground then tightened up..Still tryin to figure out what is causing the problem on his rig. Hate to go to new LCA's if I dont have to but if he cant fix his problem then I might have to spend money on an adj front track bar and adj LCA's.....Again thanks for the answer. Im glad I asked before I started the project...Lil pissed that Rough Country wasnt more informative in their instructions though!!!!!!

 

I have the Series II kit which may be what you have or you have one step up. I do have to agree with you on the instructions. THEY SUCK!!!! When installing the front brakeline brackets you may have to reach in and unhook the brakelines from some of the hold down clamps to get enough slack to extend them. Also in the back for the coil spacers, make sure you have the right bolts. THey had a metric and standard bolt that were similar and dumb me didn't pay attention. I tried for about a half hour to thread a metric bolt into a standard nut. I finally figured out my dumb ass mistake. But if you aren't paying attention like me it may happen. Also if you have a jack or something that could pry the axle down or get some spring compressors, it may make installing the springs easier when the spacers are in. I would also loosen up the trackbar and control arm bolts to unload them then retorque them after on the ground. Check your steering wheel alignment or your esp will go nuts. Mine was luckly ok. Its easy to adjust though. There is a thread on that.

 

most everything has CRAP instructions that comes with the parts you order. It is why I am glad there is a great forum like this one where others like to help out or have been through what you are about to do

 

if his draglink and trackbar doesn't have the same geometry angles then he will have DW. I had low speed DW and finally got rid of it. Also have him check his pitman arm nut, my worked it self loose and that didn't help matters any torque spec on the pitman arm nut is 185 ft LBS.

 

Thanks I will let him know.. He also thinks it might be his caster..It went from I think 4.5 to 3.5 if that makes sense..Checked mine and its at 5 before the lift so maybe 3.5 is out of range for the jk specs. Zone sells a square cam loc( I think thats what its called) instead of the round one that can move after wheelin and throw everything off. The square one fits into the lca mount and depending on which way you place the bold hole it can give you 2 degrees of caster adjustment with stock lca's. Right now its just a theory but if that is what it is I dont think there is any reason why you cant spot weld the cam loc into place to avoid any movement even though its square to begin with. We will see in a couple days when they arrive. I willalso run the above suggestion by him. thanks

 

For this 2.5 BB you will not need LCA. I've had mine in for about 2 years and it's been fine.. I don't even have the rear trackbar bracket.. Mine actually drove better then stock...

 

I have like 3 sets of those cambolts, I never installed them because of the horror stories I read. With just a BB lift you won't need LCA's or UCA's . I ran a Tera BB and never had any trouble. stock caster is around 4.5

 

Ya..That was my understanding also that there was no need for LCA's or UCA"S with the 2.5 bb but another guy on here( i cant remember his name) was taking about how new or pretty new jk's seem to pick up death wobble alot easier than older models. Since mine is a brand new jk I figure Ill just install the lift and hope for the best. Ill deal with the death wobble if it happens...No sense in worrying about "what if's".
Hopefully my buddy can get his sorted out without havin to drop a ton of cash to get it right..
install is set for a couple weeks from now...we will see then...Thanks for the info fellas...
