3.5" 2018-2026 Jeep Wrangler JL (4 Door) J-Krawl Long Arm Lift Kit by JKS

The JKS JSPEC229KFP 3.5-Inch J-Krawl Long Arm Suspension Lift Kit for 2018-2026 Jeep Wrangler JL 4-Door models is a high-performance suspension system that increases ground clearance, suspension travel, articulation, and overall control on the street and trail. The system replaces the factory short-arm suspension layout with true long-arm geometry using heavy-duty 2-inch diameter control arms, adjustable track bars, high-clearance mounting brackets, JKS 3.5-inch dual-rate coil springs, and selectable FOX shocks. Coil spring choices include standard-rate coils or heavy-duty-rate coils, while shock options include FOX 2.0 Performance Series, FOX 2.5 Performance Series, and FOX 3.0 Factory Race Series shocks.

The long-arm suspension geometry uses extended control arms and repositioned mounting points to promote smoother axle movement throughout the suspension travel range. Heavy-duty 2-inch steel control arms provide the strength required for demanding off-road use, while specially designed control arm bushings balance articulation with predictable road handling. Adjustable track bars provide precise axle positioning, and optimized anti-dive and anti-squat geometry helps maintain stability during braking and acceleration. The long-arm configuration also reduces suspension bind, allowing the axles to cycle more freely and maintain traction over uneven terrain.

JKS dual-rate coil springs provide approximately 3.5 inches of lift and are available in standard-rate or heavy-duty-rate configurations. The progressive spring design delivers compliant response during lighter-load driving while increasing spring support as the suspension compresses. Standard-rate coils provide a balanced configuration for typical vehicle weight, while heavy-duty-rate coils offer additional support for Wrangler JL builds carrying added equipment and accessory weight. High-clearance frame brackets, replacement rear control arm mounts, rear axle brackets, and a redesigned transmission crossmember/control arm mount work together to improve suspension geometry while keeping critical components positioned above the bottom of the frame rails.

Three FOX shock packages let you configure the JSPEC229KFP system for different levels of damping performance. FOX 2.0 Performance Series shocks provide dependable monotube damping for balanced street and trail use, while FOX 2.5 Performance Series shocks provide increased oil capacity and damping capability for more demanding driving conditions. FOX 3.0 Factory Race Series shocks deliver the highest level of performance with large-diameter race-derived damping technology designed for aggressive off-road use. With clearance for up to 37x12.50 tires and a complete long-arm suspension architecture, the JSPEC229KFP provides a comprehensive upgrade for Wrangler JL builds focused on articulation, ground clearance, handling, and off-road capability.
