Rock Krawler 07-18 Jeep Wrangler JKU 4DR 3.5in Lift Triple Rate Coil Springs - Rear

These rear coil springs from Rock Krawler are built with a triple rate design, meaning they have three distinct spring rates within a single spring. This advanced setup is specifically tuned to provide a balanced ride for your 2007-2018 Jeep Wrangler JKU 4-door, offering a 3.5-inch lift. The triple rate system works to give you a softer initial rate for comfortable on-road manners, a stiffer middle rate for control during normal driving, and a firm upper rate that engages during full suspension compression, like when you're off-roading or hitting a bump hard.

Rock Krawler has engineered these springs to work with your JKU's suspension geometry, ensuring they fit right and perform as intended. The goal here is to improve your Jeep's capability off-road while maintaining a more comfortable ride than you might expect from a lift kit. This means you get better articulation when you need it, without sacrificing too much comfort for your daily drive.

When installing these rear springs, you'll be working with a component designed to integrate with your existing suspension setup. They are intended to provide the lift and improved suspension response you're looking for, making your JKU more capable for adventure.
