When the JKS engineering team set out to develop a long arm system for the Jeep JL, the mission was clear—create a suspension that delivers exceptional on-road manners without sacrificing off-road performance. The result is a thoroughly refined system built from real-world customer feedback, extensive testing, and a relentless focus on performance, durability, and quality. This isn’t just a lift kit—it’s a complete suspension solution for Jeep owners who demand the best of both worlds.
Proudly made in the USA, this system features true long arm geometry with heavy-duty 2-inch diameter control arms, adjustable track bars, and precision-engineered brackets designed to maximize both strength and ground clearance. Every component works together to provide predictable handling, excellent high-speed drivability, and impressive articulation on the trail.
On the road, performance is achieved through a refined 4-link geometry with track bars, optimized control arm length, and a carefully balanced joint and bushing design. This results in a smooth, controlled ride with confident handling at highway speeds. Off-road, the system is engineered to reduce the binding commonly found in 5-link systems, allowing the suspension to cycle freely and maintain traction across uneven terrain. Carefully tuned anti-dive and anti-squat geometry further enhance stability under braking and acceleration, delivering a balanced driving experience in any environment.
Ground clearance is a key focus throughout the design. All frame brackets are engineered to sit above the bottom of the frame rails, ensuring nothing hangs down to catch on rocks or obstacles. The system maintains a smooth underside profile with no exposed bolts or plates below the frame. High-clearance rear axle brackets and replacement control arm mounts improve both geometry and trail capability, while a replacement crossmember doubles as a control arm mount without sacrificing clearance. Every detail is designed to maintain or improve factory ground clearance while increasing strength and durability.
This kit comes does not include shocks or springs, its an control arm upgrade which included front and rear control arms, with all mounting brackets.
Additional features include heavy-duty frame brackets that do not interfere with ground clearance, true long arm construction for improved suspension performance, replacement rear control arm mounts for proper geometry, and predictable suspension movement with increased flexibility. Steering correction is required for lift heights over 3.5 inches to maintain proper handling.
Whether you're logging miles on the highway or pushing your Jeep hard on the trail, the JKS JL Long Arm Kit delivers a balanced, high-performance suspension system built to handle it all without compromise.
