Rock Krawler RK07959K 2.5in Rear Triple Rate Coil Spring Kit for Jeep JLU 4xe

The Rock Krawler RK07959K is a 2.5-inch rear coil spring kit engineered specifically for the heavier Jeep Wrangler JLU 4xe plug-in hybrid platform. Designed to work with the added weight of the 4xe battery pack, this kit delivers proper lift height, improved ride quality, and reliable off-road performance without compromising on-road drivability.

At the heart of this kit are Rock Krawler's signature Triple Rate coil springs, which combine three progressive spring rates into a single coil. This design maximizes effective suspension travel, prevents the spring from unseating at full droop, and transitions smoothly from light street driving to aggressive off-road articulation. The springs are preset to minimize settling over time, shot peened for stress relief, and finished in a durable black powder coat.

The included rear spring correction pads are a critical component — they reduce the spring bow inherent in the factory JL/JLU coil perch geometry, improving spring alignment and overall suspension geometry at ride height.

Kit Includes:

• (2) JLU 4xe-specific rear triple rate coil springs — 2.5 in. lift height
• (2) JL rear spring correction pads
• Black powder coat finish
• Limited Lifetime Warranty

Rock Krawler's triple rate rear coil springs provide 2.5 inches of lift with enough clearance to run up to 38-inch tires depending on model and build configuration. Whether you're building a daily-driven trail rig or a weekend off-roader, the RK07959K delivers the performance and durability Rock Krawler suspension systems are known for.
