RockJock 3" Lift Front Coil Springs (TJ LJ JK 4Dr 3" & JK 2Dr 4") MIL ARTES MUJER: Manualidades con gomitas dulces. 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.

(however, this number is rather arbitrary due to variances in vehicle load, or lack thereof) Spring Free Length = 21. 600 in. Spring Rate = dual rate w a combined rate of 70 lbs. Notes: Actual lift amount will vary due to factory variances from vehicle to 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. As a general rule, purchasing the same stated amount of lift rear springs to match the lift amount of these front springs will provide a level finished vehicle. However, again, vehicle load or lack there of will directly affect vehicle height, hence we have various rear springs to accommodate different vehicle load applications. See all of the spring options under the spring section of the vehicle platform you are working on to view all of the available rear springs offered. Using the correct bump stop for these springs is critical! See our JK Bump Stop Kit here or our TJ LJ XJ MJ ZJ Bump Stop Kit options here.
