3.5" 2018-2026 Jeep Wrangler JL (4 Door) J-Krawl Long Arm Lift Kit (w/Fox 2.5 Factory Race Coilovers) by JKS

The JKS JSPEC231PES / JSPEC232PES 3.5-Inch J-Krawl Coilover Long Arm Suspension Lift Kit for 2018-2026 Jeep Wrangler JL 4-Door models is a high-performance suspension system engineered to improve ground clearance, articulation, suspension travel, and on-road stability. The system combines true long-arm suspension geometry with FOX 2.5 Factory Race Series dual-rate coilovers, heavy-duty 2-inch control arms, adjustable track bars, high-clearance mounting brackets, and geometry-correcting suspension components. Front bump stop configurations are available with either rubber bump stops or FOX 2.0 Factory Race Series Hydro Bump Stops, allowing you to tailor the system to different levels of off-road performance.

Heavy-duty 2-inch diameter long arms replace the shorter factory control arm arrangement to improve suspension movement throughout the increased travel range. Revised control arm lengths and mounting locations reduce suspension bind while improving axle movement and traction over uneven terrain. The geometry is engineered around controlled anti-dive and anti-squat characteristics to maintain stability during braking and acceleration, while adjustable track bars provide precise axle positioning. Custom control arm bushings balance durability with controlled movement to maintain predictable pavement handling without restricting trail articulation.

FOX 2.5 Factory Race Series Cerakote coilovers provide the damping and spring control needed for the 3.5-inch lift system. Dual-rate coil springs support controlled road manners while allowing greater off-road suspension flexibility, and DSC dual-speed compression adjustment provides additional tuning capability for low- and high-speed compression damping. High-clearance frame brackets, replacement rear control arm mounts, and an integrated transmission crossmember/control arm mounting structure are positioned to preserve underside clearance and minimize components hanging below the frame rails. This design combines increased suspension strength with a smoother underbody profile for navigating rocks and other trail obstacles.

The JSPEC231PES is available with either rubber front bump stops or FOX 2.0 Factory Race Series Hydro Bump Stops. Rubber bump stops provide a durable progressive stop for street driving and lower-speed off-road use, while FOX 2.0 hydraulic bump stops add controlled damping as the suspension approaches full compression, reducing harsh bottom-out forces during higher-speed or more aggressive terrain. With support for up to 37x12.50 tires and a complete long-arm coilover suspension architecture, the J-Krawl system provides a substantial upgrade for Wrangler JL builds focused on articulation, clearance, high-speed stability, and demanding trail performance.
