6" 2018-2026 Jeep Wrangler JL (4 Door) J-Krawl Long Arm Lift Kit by JKS with Fox Shocks

The JKS JSPEC237KFP / JSPEC238KFP 6-Inch J-Krawl Long Arm Suspension Lift Kit for 2018-2026 Jeep Wrangler JL 4-Door models is a complete high-clearance suspension system designed to increase ground clearance, articulation, suspension travel, and vehicle stability. The system combines true long-arm geometry with heavy-duty 2-inch diameter control arms, adjustable track bars, JKS 6-inch HD dual-rate coil springs, high-clearance suspension brackets, and selectable FOX shocks. Shock choices include FOX 2.0 Performance Series or FOX 2.5 Performance Elite shocks, while steering correction can be configured without a drag link flip kit for Jeeps already equipped with compatible steering correction or with the APEX Drag Link Flip Kit.

JKS long-arm geometry replaces the shorter factory control arm setup with extended arms and revised mounting locations that let the axles move more freely throughout suspension travel. Heavy-duty 2-inch steel control arms provide the strength needed for demanding off-road use, while custom control arm bushings balance suspension flexibility with controlled highway handling. Carefully engineered anti-dive and anti-squat characteristics help stabilize the chassis during braking and acceleration, and adjustable front and rear track bars provide precise axle positioning at the increased ride height.

Six-inch JKS HD dual-rate coil springs add ride height while providing increased support for Wrangler JL builds carrying larger tires, aftermarket bumpers, recovery equipment, or other added weight. High-clearance frame brackets sit above the bottom of the frame rails to preserve valuable underside clearance, while replacement rear control arm mounts and axle brackets improve suspension geometry without adding unnecessary low-hanging components. A replacement transmission crossmember also serves as a reinforced long-arm mounting structure, creating a strong and integrated foundation for the suspension system.

Damping can be configured with FOX 2.0 Performance Series shocks for balanced street and trail control or FOX 2.5 Performance Elite shocks for increased damping capacity and more demanding off-road performance. Steering configurations include no drag link flip kit for vehicles already equipped with the required steering correction or the APEX Drag Link Flip Kit for builds that still require it. With support for 40x13.50 tire combinations and a complete 6-inch long-arm suspension architecture, the JSPEC238KFP provides a comprehensive upgrade for Wrangler JL builds focused on maximum clearance, articulation, stability, and aggressive trail capability.
