Rock Krawler 3.5" Adventure X Suspension Mid Arm System for 07-18 Jeep Wrangler JK
Adventure-X High Clearance Lower Arms: Both front and rear lower control arms feature a specific upward bend. This design provides maximum ground clearance, allowing you to crawl over obstacles that would snag or damage standard straight arms.
Total Geometry Adjustability: With all eight arms being fully adjustable, you can perfectly center your axles and dial in your caster and pinion angles. This is essential for a 3.5" lift to maintain high-speed stability and prevent premature U-joint wear.
Maintenance-Free Pro Flex Joints: These joints are 100% service-free and require zero greasing or rebuilding. They offer silent operation and high-misalignment capability, giving you "race-level" articulation without the "race-level" maintenance.
Massive Lateral Rigidity: The included 1.5" O.D. solid steel adjustable front track bar is nearly indestructible. It keeps the front axle perfectly centered and provides a firm, responsive steering feel that hollow factory bars cannot match.
Triple-Rate Spring Performance: These coils provide three distinct spring rates, ensuring a plush initial ride for daily driving while ramping up to provide a stable, firm platform for heavy trail loads and high-speed impacts.
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-X Mid-Arm System is the ultimate performance-oriented suspension for the Jeep Wrangler JK owner who wants to dominate technical trails while maintaining a refined street ride. At 3.5 inches of lift, the JK's factory geometry is under significant stress; this kit addresses that by providing all eight adjustable Adventure-X control arms. These arms feature a distinct high-clearance bend and are forged from 1.75" O.D. solid steel, allowing you to perfectly reset your caster and pinion angles. This level of adjustability is critical for eliminating "flighty" steering and driveline vibrations that often occur when moving to a taller lift height and 35-inch or 37-inch tires.
Engineered for extreme articulation and zero maintenance, this system utilizes Rock Krawler’s proprietary Pro Flex Joints. These joints provide a silent, bind-free experience on the road while allowing the axles to flex significantly more than factory rubber bushings. Paired with a 1.5" O.D. solid steel adjustable front track bar and Triple-Rate Coil Springs, the Adventure-X system ensures your JK feels planted and predictable. Whether you are navigating a high-speed desert wash or crawling through a jagged rock garden, this system provides the structural "beef" and geometry correction required for a professional-grade 3.5" build.
