The Rock Krawler Suspension JL35X2LA-4D is a 3.5 inch X-Factor X2 Long Arm System specifically designed for Jeep Wrangler JL Unlimited (4-Door) owners who want to push their vehicle to its limits with hardcore rock crawling. This professional-grade suspension system represents the ultimate in JL long arm technology, combining maximum articulation with exceptional off-road performance and on-road stability.
Advanced 3-Link Suspension Design:
The X2 Long Arm System features an independent 3-link design front and rear for maximum articulation and off-road performance. The proprietary design utilizes double adjustable front and rear upper control arms that upsize factory hardware to 14mm with 2 3/8 inch mounting width and 1 inch Pro Krawler joints at each end. The arms themselves are chromoly solid steel construction meant to carry all suspension forces.
X2 Rear Suspension Geometry:
The rear suspension provides adjustable anti-squat with X2 rear suspension geometry featuring enhanced rear instant centers and rear roll centers. New high clearance axle mounts provide 4.5 inches of ground clearance under the rear axle compared to stock, while rear upper shock relocation brackets ensure you do not lose any shock travel.
Premium Components and Engineering:
- Adventure Series maintenance-free joints at frame connections of lower control arms to reduce grease points and provide excellent vibration absorption
- Chromoly solid steel construction for maximum durability
- 14mm upgraded hardware with 2 3/8 inch mounting width
- 1 inch Pro Krawler joints for superior articulation
- OEM-style heat shield thermal barrier protection for front control arm joints at the frame
- Triple-rate coil springs for superior ride quality
Performance Benefits:
The system feels stable, safe and strong whether driving highways or trails, running the stock drivetrain or pushing high horsepower through the chassis. The combination of high clearance long arms and 3-link suspension geometry lets you dominate the trails. This system accommodates up to 37-38 inch tires depending on fender configuration.
Installation Notes:
This is a comprehensive long arm system that requires welding of frame-side mounts and removal of OEM control arm mounting points. Professional installation is recommended. Shocks sold separately unless otherwise specified.
