Rock Krawler JK35AS-2S1 3.5" Adventure System Suspension Mid Arm System with RRD 2.25" IFP Shocks for 07-18 Jeep Wrangler JK 2-Door
Precision Caster Correction: The included adjustable front lower control arms allow you to dial in the perfect amount of caster. This is the single most important adjustment for ensuring your JK tracks straight and remains stable during high-speed driving.
Maintenance-Free Pro Flex Joints: These arms feature Rock Krawler’s proprietary joints, which are 100% service-free and silent. They offer high-misalignment capability for impressive trail flex without the need for constant greasing or rebuilding.
Heavy-Duty Lateral Stability: The 1.5" O.D. solid steel front track bar is a massive upgrade over the hollow factory unit. It eliminates the lateral axle shift caused by the lift and provides a firm, responsive feel to the steering wheel.
Advanced Triple-Rate Coils: Unlike standard linear springs, these coils provide three distinct zones of resistance. This results in a "best of both worlds" scenario: a smooth street ride and a firm, supportive rate for aggressive off-road maneuvers.
"Abuse It" Lifetime Warranty: Every hard part in this system is backed by Rock Krawler’s legendary lifetime warranty. If you manage to bend or break a control arm or track bar on the rocks, they will replace it, making this a true lifetime investment for your build.
Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.
The Rock Krawler 3.5" Adventure Mid-Arm System for the Jeep Wrangler JK is the heavy-duty "sweet spot" for owners who want to run 35-inch or 37-inch tires while maintaining excellent road manners. Because a 3.5-inch lift on the JK platform significantly alters the suspension's relationship with the ground, this kit is specifically designed to correct the front-end geometry using Adventure Series adjustable front lower control arms. These solid steel arms allow you to reset your caster to eliminate the "flighty" steering and "death wobble" tendencies that often plague taller JK lifts, ensuring the Jeep feels stable and centered at highway speeds.
This system provides a significant boost in ground clearance, which is essential for the JK’s breakover and departure angles on technical trails. It features Rock Krawler’s signature Triple-Rate Coil Springs, which are uniquely tuned to provide a plush, compliant ride over small road chatter but offer a progressive rate that prevents "bottoming out" when the Jeep is loaded with steel bumpers, a winch, or heavy trail gear. By including a 1.5" O.D. solid steel adjustable front track bar, this kit also ensures your front axle remains perfectly centered, providing the lateral stiffness needed for crisp, predictable steering response.
