This is the gentle one. 1.5 inches of lift on triple-rate coils, with the geometry fixes a plain spacer lift skips and a street ride that is meant to beat the factory springs. Rock Krawler says it clears up to 38 inch tires depending on the model, and it keeps 0.5 inch of the factory rake. It bolts in, and the lower arms use the same service-free Adventure Series joints as the bigger systems.

Why this system
- 1.5 inches of lift with clearance for up to 38 inch tires, depending on the model, per Rock Krawler.
- Keeps 0.5 inch of the factory rake.
- Triple-rate front coils and quad-rate rear coils, tuned for the Gladiator. Rock Krawler says they ride better than the factory springs on the street, and they have the free length to stay seated and flex off-road.
- Coil spring correction seats take out the spring bow built into the factory setup and correct vehicle lean, so the Jeep sits level on all four corners.
- An adjustable front track bar centers the front axle at the new ride height, so there is no compromise in handling.
- Service-free Adventure Series joints in the lower control arms. Rock Krawler quotes 70 degrees of total misalignment when they are paired at the frame and axle ends, which greatly reduces the bind of the factory JT lowers.
- Rock Krawler lists this kit as upgradable to its long arm system.
- Lifetime warranty coverage, as listed by Rock Krawler.

Fitment and what else you'll need

Rock Krawler bases its lift heights on Rubicon models in a standard build (front bumper and winch, rear bumper and full-size spare). If you delete the spare, drop 1 inch of rear coil lift height; for an overland style or heavily up-fitted rear end, go up 1 inch.
