Rock Krawler JL35X2PLA-4S1 3.5 Inch X Factor X2 Pro Elite Long Arm Suspension Lift Kit Stage 1 - 4 Door

The Rock Krawler JL35X2PLA-4S1 is a 3.5-inch X Factor X2 PRO ELITE Long Arm Suspension System Stage 1 built for the 2018-present Jeep Wrangler JL 4-Door (Unlimited). Engineered for hard core rock crawling and serious trail use, this long arm suspension lift kit delivers maximum articulation, optimized geometry, and exceptional on- and off-road performance.

PRO ELITE Billet Aluminum Lower Control Arms:

The "PRO ELITE" designation means this system is equipped with PB&J (Pure Beef and Jealousy) billet aluminum lower control arms — custom machined in-house from solid square stock billet aluminum. These arms are maintenance-free and built to handle extreme abuse on the trail or the street.

Key Features:

• 3.5 inches of lift — supports up to 40-inch tires depending on model configuration
• Independent 3-link design front and rear for maximum articulation and off-road performance
• Double adjustable upper control arms — upgrades factory hardware to 14mm, 2 3/8-inch mounting width with 1-inch Pro Krawler joints at each end, front and rear
• X2 rear suspension geometry — enhanced rear instant centers and roll centers for superior trail handling and stability
• 4.5 inches of rear axle ground clearance gain via high clearance axle mounts compared to stock
• Rear upper shock relocation brackets — preserve full shock and suspension travel
• Adventure Series maintenance-free frame joints — reduce grease points and provide excellent vibration absorption and joint misalignment capability off-road
• Triple-rate coil springs — all four coils work together to deliver on-road comfort that outperforms factory linear rate springs, with proper free-length for off-road articulation
• Spring correction pads — reduce factory spring bow front and rear
• Track bar geometry corrections front and rear — precisely center the axles for zero compromise in on-road handling
• Stage 1 shock package included for a well-tuned, trail-ready setup out of the box

The X Factor X2 Long Arm system relocates the lower control arm frame mounts to achieve true long arm geometry, improving suspension travel, reducing driveline angles, and unlocking the full articulation potential of the JL platform. This system is completely upgradeable within the Rock Krawler JL lineup and is backed by Rock Krawler's Abuse Proof Lifetime Warranty on all hard parts.
