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.
Our 3 1/2 in. lift (over standard model springs) rear coil springs for the 2020-up JT Gladiator 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.
