Wrangler TJ 1997-2006 Jeep 4WD - 4" Lift Front & Rear Dual Rate Coil Spring Kit (set of 4) by JKS

Increase clearance, performance, and ride quality with the JKS JSPEC3400 4-inch lift dual-rate coil spring set, designed specifically for Jeep Wrangler TJ models. This complete spring package includes matched front and rear coils engineered to deliver a true level 2 lift while maintaining excellent ride characteristics.

The dual rate design provides a smooth, comfortable ride during normal on-road driving, then transitions to a firmer spring rate as suspension travel increases off-road. This improves vehicle control when crawling over obstacles, navigating uneven terrain, or carrying additional gear. With a longer free length than stock springs, JSPEC™ coils allow the use of longer shocks, increasing wheel travel and improving articulation. Whether the vehicle is loaded for an extended expedition, set up for technical rock crawling, or carrying passengers for daily driving, these springs deliver consistent performance and predictable handling in all conditions. Engineered for durability and balanced performance, JKS JSPEC™ coil springs provide the ride quality and capability required for both on-road comfort and demanding off-road use.
