Features & Product Details
RockJock is famous for their 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 RockJock's 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 rear coil spring set for 3.6L V6 and 2.0T I4 drivetrain equipped JL Wrangler Unlimited vehicles provide 3 1/2 in. of lift. Their springs directly replace the factory coil springs and are designed to work with RockJock Johnny Joint suspension systems or other manufacturers’ 3 to 5 in. lift kits.
