Rock Krawler X-Factor Series Mid-Arm No Limits 392 Suspension Lift Kits

Rock Krawler X-Factor Series mid-arm No Limits 392 lift kits are engineered specifically for Jeep JLU 392 owners who want a bolt-in suspension system with maximum articulation and confident street manners. These systems combine triple-rate coil springs for a controlled, comfortable ride with the strength and tunability of fully adjustable X-Factor upper and lower control arms, allowing precise caster and pinion angle adjustment. The "No Limits" name comes from the included front sway bar links designed to retain full function of the factory electronic sway bar disconnect on select models. Geometry corrections (spring correction pads to reduce factory spring bow plus front and rear track bar geometry corrections) help center the axles and maintain stable on-road handling. Get a lift system that is designed to flex hard on the trail, then track straight on the drive home when you order the Rock Krawler X-Factor Series mid-arm No Limits 392 suspension lift kit best suited for your application.
