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

Rock Krawler designs their X-Factor PRO No Limits mid-arm 392 suspension systems for Jeep JL 392 owners who want a true bolt-in system that delivers excellent highway manners with the durability and articulation Rock Krawler is known for. Built around service-free Adventure Series control arm joints, these kits reduce factory suspension bind while allowing precise caster and pinion angle adjustment to restore proper geometry. Fixed lower and adjustable upper control arms (solid 7075 aluminum) provide up to 95 degrees of misalignment when paired with Pro-X Krawler and Adventure Series joints, helping the suspension move smoothly through its travel without sacrificing ride quality. Tuned triple-rate coil springs, spring correction pads, and integrated track bar geometry corrections properly position the axles and reduce spring bow, while maintaining predictable handling on and off the road. Get a lift system designed to flex hard on the trail and track straight on the drive home when you order the Rock Krawler X-Factor Pro Series mid-arm No Limits 392 suspension lift kit best suited for your application.
