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

JSPEC1451 JKS JSPEC 4" Lift Dual Rate Front Coil Springs are designed to deliver increased ground clearance, improved ride quality, and enhanced off-road performance for 2018–2026 Jeep Wrangler JL 4-Door models. This kit includes a matched pair of front coil springs engineered to provide approximately 4" of lift while maintaining balanced suspension behavior.

The dual rate spring design provides a smooth, comfortable ride during normal driving conditions, then transitions to a firmer rate as suspension compression increases. This progressive spring action improves control during off-road articulation, uneven terrain, and dynamic driving situations. The extended free length also allows compatibility with longer shock absorbers to maximize available wheel travel.

Available in both Standard Rate and Heavy Duty Rate options, JSPEC1451 allows tuning based on vehicle setup and added weight such as bumpers, winches, armor, or overland gear. JKS J-Rated progressive springs increase spring rate as compression increases, maintaining comfort during light-load driving while delivering the support needed under heavier loads.
