* Unique to the 2012 and newer model JK, the engine, tranny and transfer case rest in the frame at a steeper "Front High" angle, plus the exhaust cross-over pipe is closer to the front driveshaft. Suspension travel must be limited, or the factory front driveshaft will make contact with the exhaust crossover pipe. Even if the exhaust is re-routed, the driveshaft will bind at the transfer case end when the suspension is at full extension. Superlift prevents factory driveshaft damage by including a unique front axle limiting strap tested to 19,630 lbs. resistance. The reduced travel is not noticeable on-road, although an aftermarket replacement, dual Cardan (CV) style front driveshaft is recommended for aggressive off-roading. If this type driveshaft is used, you simply discard the limiting strap and full extension travel is restored. We recommend Tom Wood's Custom Driveshafts (4xshaft.com).
