RJ-154101-101 - JL (Diesel, 392, 4XE) or JT (Gas Engines) 3.5 in. Lift Front Coil Springs

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.
This specific coil spring set for JL Wrangler and Unlimited, EcoDiesel and 392 engine equipped vehicles, as well as JT Gladiator 3.6L V6 vehicles provides a 3 1/2 in. lift (over standard height factory) front coil springs. Our springs directly replace the factory coil springs and are designed to work with RockJock Johnny Joint suspension systems or other manufacturer's 3 to 5 in. lift kits. These springs, besides lifting the vehicle 3 1/2 in., also provide an improved ride.

• Actual lift amount will vary due to factory produced vehicle variances as well as weight of added on aftermarket equipment.
