Rock Krawler JL35X2PLA-4D 3.5 Inch X Factor X2 PRO Long Arm Suspension Lift Kit 4-Door

The Rock Krawler 3.5" X-Factor X2 PRO Long-Arm Suspension System is a purpose-built long-arm lift kit engineered for serious off-road performance on the Jeep Wrangler JL 4-Door (gas models). Delivering a 3.5-inch lift with industry-leading geometry, this system is designed for Wrangler owners who demand maximum articulation both on the trail and on the street.

X2 Long-Arm Geometry:

• Independent 3-link design front and rear for maximum articulation and off-road performance
• X2 rear suspension geometry with enhanced rear instant center and rear roll center for improved anti-squat and stability
• Double adjustable front and rear upper control arms upsize factory hardware to 14mm with 2-3/8" mounting width and 1" Pro Krawler joints at each end
• Upper control arm is a chromoly solid steel arm designed to carry the full forces of the suspension system

PRO-Level Lower Control Arms:

• Features Rock Krawler's signature PB&J Billet Aluminum lower control arms — custom machined in-house from solid square stock billet aluminum bar
• CNC machined for precision fit and engineered for maximum strength and abuse resistance
• Long-arm length for improved suspension geometry and caster correction

Adventure Series Joints & Hardware:

• "Adventure Series" maintenance-free joints at the frame connections of the lower control arms reduce grease points while providing excellent vibration absorption
• Proper joint misalignment capability for demanding off-road use
• High clearance axle mounts provide additional ground clearance under the rear axle compared to stock
• Rear upper shock relocation brackets ensure no loss of shock travel

Ride Quality & On-Road Manners:

• System is tuned to feel stable, safe, and strong whether running the stock drivetrain or pushing high horsepower
• Includes correction pads to reduce the spring bow inherent in the factory JL setup
• Engineered to perform equally well on the street, in tow, and on the trail

Rock Krawler recommends installing limiting straps after installation to prevent over-extension of suspension components, and a professional alignment by an off-road experienced specialist after any suspension upgrade.
