Ive got the 3.5 super flex with adjustable track bar. Love the lift. Ive beat the snot outta it and it still sits and rides great. Been on for 1 year now. Also heat the rear leaf bolts up before you loosen them. I didnt and had to sawzall them out and re-tap the bolt holes.(pain in the #$%) Im running 32" bfg mudterrain km's. Not the km2. I LOVE these tires. You can still find them, a gotta look tho. Anyway good luck with the lift.

 

Thanks man should come on wed or thurs ... I think i got to get the 32 BFG AT's though... I have to use this as my dd and i have drill 2 hrs away...

 

well my lift is about 85% done now, its sitting back down on all 4 wheels, temporarily until my new wheels come and i get the 31's put on them.

I still have some things left to do, but overall the major part is done.

just wanted to chime in here and make a note that my 3.5 super ride coils/leafs are sitting at about 4.5 over stock. now, im sure its going to settle, but i dont think its going to settle an inch from where it is now.

front pre lift was 17.5, after lift is 22.

Rear pre lift was 17, after 21.5

and thats with about 150lbs in the back.

and the front feels STIFF as all can be, i can barely move it by hand. i know the spring rate is like 220 or 240 or something crazy, but will be nice when i add a heavy bumper and winch down the road.

 

just an observation here. today i pulled the front RE springs and swaybar discos from my 01 that had the 3.5" superflex kit on it. i am swapping in the 4.5" RC coils i have and RC discos.

the RE discos are being replaced because the pins that mount to the axle are toast. one had already been replaced(rendering the disco feature null), and i noticed the other was just about to go. the reason? they are made from a weak material(i think alu, not sure have to check tomorrow), and they take a bolt. this means there is hardly any material left to handle the stress the swaybar puts on it, it looks like 3/16 all around. bad design.

i do not know how the rc ones will fare, but they use a pin on the axle mount as well, it is steel and it is a one piece design that takes a nylock nut on the other end....much stronger right there.

 

I've got a 4.5 rubicon express lift on my xj and it is stiff as can be but I took the sway bars off it still rides rough as can be but flexes like no other I'm not going to use any other lift kit after this one

 

Unless I go to a 4-link haha

 

Rough riding is a very subjective description.

A couple things to consider:
Shock absorber condition and/or quality.
Lower control arm angles.

Either one of these can greatly affect ride quality regardless of which brand lift you're running.

 

As FrankZ said take into consideration the quality of the shocks. Shocks are valved differently to allow a certain amount of oscillation (bouncyness if you will) in the springs and this is one factor in determining ride quality.

 

Amen to this. The only reason my RE kit rides any rougher than stock is because im still on short arms, you can just /feel/ that the axle is pushing back against the arms instead of cycling up and down in a normal fashion. The rear springs feel better than stock to me. Im also running pro comp es9000 shocks all the way around.

 

i thought the RE lift rides very well, but the jeep also came with RE monotube shocks installed and i think they make a big difference. my 90 with the 4.5 RC kit has twin-tube whitebodies in it and it rides a fair bit rougher..

shocks, shackle angles, and control arms all make a huge difference in ride quality....regardless of lift brand.

 

Mine rides good on pro comp 3000s

 

is this what the lower control arm drop brackets are for to try and keep the front axle from binding causing a stiff ride?

 

Drop brackets decrease the severity of the control arm angles on taller lifts, aide in setting the proper wheelbase, correct the pinion and caster angles....and increase the ride quality.

 

My XJ has the RE 3.5" kit with the replacement rear springs (I forget the name of the kit now). Took out the bottom leaf. It leveled out the Cherokee and really smoothed out the ride. Added 3/4" spacers up front and extended shackles in the rear. I run 32 x 10.5" Swamper TSL Radials on Grizzly wheels. I would recommend this lift in a minute. Great ride, great flex.

Up front are Bilstein 5150 shocks. Outback are Bilstein 5100's.

I have pictures in my album.

 

Nice ride! I have the re3.5 super flex and it's good
