Wrangler JL 2018-2026 Jeep 4WD - 4" Lift Rear Dual Rate Coil Spring Kit (Pair) by JKS

JSPEC1458 JKS JSPEC 4" Lift Dual Rate Rear Coil Springs are engineered to increase ground clearance, improve ride quality, and enhance off-road performance for 2018–2026 Jeep Wrangler JL 4-Door models. This kit includes a matched pair of rear coil springs designed to deliver approximately 4" of rear lift while maintaining balanced suspension dynamics.

The dual rate progressive spring design provides a smooth and comfortable ride during normal on-road driving, then transitions to a firmer rate as suspension compression increases. This improved load management enhances control during articulation, uneven terrain, and when carrying additional cargo or overland equipment. The longer overall spring length also allows the use of longer shock absorbers to maximize wheel travel.

Available in both Standard Rate and Heavy Duty Rate options, JSPEC1458 allows tuning based on vehicle setup and added weight such as bumpers, armor, rooftop tents, or gear. JKS J-Rated progressive coil springs increase spring rate as compression increases, maintaining comfort under light load while delivering the support needed for heavier builds.
