Product Resources
Features & Product Details
The Rock Krawler 3.5in Drive Right Mid-Arm Suspension System corrects factory suspension geometry when lifting your Jeep Wrangler JL, so it handles, steers and rides better than stock. An adjustable front track bar recenters the front axle and a bolt-on rear track bar relocation bracket recenters the rear axle while improving the rear roll center, eliminating dog tracking for a Jeep that drives straight and true.
Instead of adjustable upper arms that shorten the wheelbase as caster is added, the system uses high-clearance adjustable front lower control arms for caster and cross-caster adjustment while keeping the proper wheelbase. Application-tuned triple-rate coil springs deliver a smooth highway ride and strong articulation off-road. This package does not include shocks or bump stops (bump stops sold separately as RK07124). The system can later be upgraded to other Rock Krawler systems.
