RockJock 4-Inch Rear Lift Coil Springs (04-06 Jeep Wrangler TJ Unlimited)Find parts that fit my vehicle

Description. RockJock® is famous for our coil springs! The John Currie secret recipe is renowned for being the best on-road ride and the most off-road flex, all in one spring!

Some of the secret (but not all!) to our dual rate springs is a soft initial rate that absorbs small bumps and trail chop, to deliver a smooth, comfortable ride, while a firmer secondary rate helps soak up larger impacts and reduce bottoming.

A key differentiator of RockJock spec. dual-rate springs is the positioning of the crossover point between the initial and secondary spring rates so that a portion of the softer initial rate is available and active at ride height before crossing over to the firmer secondary rate deeper into the travel.

BE AWARE: with soft rate springs, effective lift heights will vary per vehicle due to factory variances from vehicle as well as the amount of weight added onto the vehicle following the installation of aftermarket equipment. Additionally, all provided lift specs. take into account that the vehicle retains the factory installed engine.

Finish is gloss black powder coat.
