The top of the line suspension for the ZJ, the Super-Flex kit upgrades all stock suspension components, creating an astoundingly capable off road performer. The 4.5" kit will clear 31x10.50", 32x11.50" or 33x10.50" tires without additional modifications.

Pros: Excellent design, well constructed parts, complete kit
Cons: Would not install myself but I'm sure those more capable would
Recommended? Yes

Comments: I recently upgraded my stock '98 Grand Cherokee, 4.0L/I6 with the Rubicon Express 4.5" kit. Very complete. The price is just for the kit - no installation or extras. I'm not much of a DIYer so I had it done locally by a very reputable business. It was not necessary to replace the drive shaft which I am thankful for. No wobble or anything. I did have an Old Man Emu steering stabilizer installed. I also upgraded my rims to some ProComp 16" and 32" Xtreme tires. Love it!

Cons: Just about everything else

Comments: I first installed the RE Superflex kit about 18 months ago on my newly acquired TJ. It was bone stock and I wanted to get a decent lift, my goal being to run 35"s. Well after lots of research I decided on the RE kit.

Getting straight to the punch, AVOID AT ALL COSTS. I know most people don't want to spend the bucks, but go for a kit with Johnny Joints... its really the only way worth doing.

This kit's rubber bushings are completely worn out after a year of mostly street driving. The "superflex" wannabe johnny joints on this thing are rusted and do not flex any longer (so superstuck would be a more appropriate name). RE will send a set of replacement bushings once, but I'm on my own for the joints.

$900 for a year and a half of use vs getting Johnny Joints that will last easily twice as long. You do the math.

Price: $800.00
Pros: Travel is excellent, good clearance
Cons: rides rougher than stock, should have held out for a long arm type kit
Recommended? Yes

Comments: Its a good kit, ride is a little too harsh for me though, mostly in the rear, tried different shocks, still takes potholes, and other road obstacles harsh, however, in the rocks, it flexes very well

Price: $1,400.00
Pros: Install was easy, good instructions
Cons: Control arms are weak, Super Flex hour glass rubber bushing wears out quick, control arm ends stretch horribly.
Recommended? No

Comments: The control arm ends stretch out too easily causing the rubber bushings to split. The metal is too weak. I HATE my control arms.

Comments: does well, i would like to upgrade to a LA though to get a little more travel. i would recommend it however for its ease to upgrade to the RE long arm and retain some of the same parts. but with a good set of disconnects there isnt much you cant conquer.
