The Currie Johnny Joint® suspension system kit is a complete package that replaces all eight stock control arms and provides a 4" lift. It is engineered to provide unrivaled articulating flexibility and performance in the most adverse off-road conditions.
That's a fairly complete kit. The upper arms aren't double adjustable. The shocks are RS9000's. @Jerry Bransford runs those shocks I believe and has mentioned they don't ride as well as the RS5000X shocks. You will need a angled rear TB relocation bracket when you get the SYE, so you'll be buying that twice. Consider a rear adjustable TB.
So the problem is when u go to a aftermarket driveshaft with the double u joint set up, the way u set the pinion angle is different from factory. There’s pics on this forum somewhere on how to set it up properly. But it will require more pinion angle so the factory location on the axle is no longer good.
The TB bracket helps to restore the side to side geometry of the TB after a lift, but I suppose you get get away without it in the short term if you get an adjustable TB. You'll need to get the angled TB relocation bracket anyway after the SYE to keep the rear TB from hitting the gas tank skid because you will be raising the pinion angle to match the new Double cardan drive shaft angle.
Hello everyone. Thanks for the post some good info. My needs are almost identical to @grawls2008. Florida Jeep. 2000 manual 4.0 44 rear 30 front 3.73. Weekend toy with some wheelin, mud, beach, 2 hour drive to good trails. Gonna run 33x12.5.probably gonna go with the zone but not the combo the straight 4’ lift. Flat fenders give me extra clearance. With the money saved on the lift gonna pick up the Tom woods sye right away. Would you recommend doing the upper control arms while I’m in there and if so which ones work well with this kit?. Was gonna go with Rustys 4.5 advanced kit but seeing some bad feedback.any input would be helpful.
