RockJock Front Coil Springs (RJ-154101-101)

Product 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. 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.

Product Brand Information

RockJock by John Currie’s roots run deep as jeeping has been a love of the Currie family for decades. In his off-roading adventures, John pushed the limits of his vehicles coming to the realization of the shortcomings of the equipment. Thus, it became John’s goal to design and build the best-performing, strongest, most durable products on the market. A Jeep suspension upgrade product line was first developed in the 1980s based around Jeep CJ and YJ vehicles. Fast forward to 1998 and John’s off-roading passion evolved into professional rock crawling competitions. In 2001, John Currie took home the 1st place trophy in the Extreme Rock Crawling Championship Series, in a RockJock equipped Jeep TJ Wrangler. This was the first of many victories and championships for John, and the victories have continued with various other drivers of RockJock equipped vehicles in numerous rock crawling, Ultra 4 and desert racing categories!
