A Balanced Rear Lift Option for Everyday JL Wranglers
The RK07017P rear coil spring set gives the Jeep Wrangler JL and JLU a 3.5 inch rear lift on gas models, or 2.5 inch on 392 Hemi models, for a moderate stance increase that still rides comfortably on the street. Rock Krawler builds the coil with staged winding so the rear suspension settles properly under load and firms up progressively at full droop. RK07017P bolts directly into the factory rear coil location.

- 3.5 inch rear lift on gas-engine JL/JLU models, 2.5 inch on 392 Hemi models
- Progressive coil winding for a comfortable street ride and confident trail travel

Does RK07017P fit the 4xe hybrid Wrangler?No, the 4xe hybrid requires a dedicated coil spring such as RK07961P due to its unique rear suspension layout.
Is RK07017P a good choice for a daily driven Wrangler?Yes, the 3.5 inch lift height of RK07017P is a popular choice for owners who want a noticeable stance change without the ride compromise of a taller lift.

Coilover Springs
Coilover springs are the replaceable compression springs that wrap around the shock body in a coilover assembly, determining ride height, spring rate, and the balance between comfort and handling stiffness. Swapping springs is the most direct way to tune a coilover setup for a new application without buying an entirely new system.Popular UpgradesLinear-rate springs in the 6 to 12 kg/mm range are the most popular choice for street performance and track day builds where predictable handling is more important than maximum compliance. Progressive-rate springs that soften on small bumps and stiffen under load are preferred for street cars that need to be both comfortable on rough roads and controlled in hard cornering. ID60 and ID65 springs are the most common inner diameter specifications across popular coilover platforms.What is the difference between linear and progressive coilover springs?A linear spring has a constant rate from full droop to full compression, providing consistent an...
