Rock Krawler JL45AX2LA-4DS1 4.5 Inch Adventure-X2 Long Arm Suspension System Stage 1

The Rock Krawler JL45AX2LA-4DS1 is a 4.5-inch Adventure-X2 Long Arm Suspension System Stage 1 engineered for Jeep Wrangler JL owners who demand the ultimate balance between daily-driver comfort and hardcore off-road performance. Designed and manufactured in the USA, this complete front and rear lift kit delivers a serious 4.5-inch lift while dramatically improving articulation, ground clearance, and suspension geometry.

Adventure-X2 Suspension Architecture:

• Full High-Clearance 4-Link Long Arm Front Suspension — replaces the factory short arm geometry with a properly engineered long arm setup for superior axle articulation and caster correction
• High-Clearance Independent 3-Link Long Arm Rear Suspension — the tried-and-true independent 3-link conversion with proprietary X2 rear suspension geometry featuring enhanced rear instant centers and rear roll centers
• 4.5 Inches of Additional Rear Axle Clearance — new high-clearance X2 axle bracket system raises ground clearance under the rear axle by 4.5 inches compared to stock
• Rear Upper Shock Relocation Brackets — repositions shocks to ensure no shock or suspension travel is lost during the lift
• Adjustable Anti-Squat — X2 rear geometry delivers tunable anti-squat characteristics for improved traction and stability under acceleration
• Adventure Series Maintenance-Free Joint Centers — each control arm features Rock Krawler's proprietary joint that isolates road vibrations like an OEM bushing, includes high misalignment capability, and uses a Teflon-lined inner sleeve for a completely service-free, grease-free design
• Heat Shield Thermal Barrier Protection — OEM-style heat shields protect front control arm joints at the frame mounting locations
• Stage 1 Shock Package Included — complete system arrives ready to install with shocks included

The Adventure-X2 system's double adjustable upper control arms upsize factory hardware to 14mm with 2-3/8-inch mounting width and 1-inch Pro Krawler joints at each end. The upper arm itself is a chromoly solid steel arm built to handle all suspension forces whether on the highway, towing, or pushing hard on the trail. The system is equally at home cruising across the country or dominating technical rock crawling terrain.

A professional alignment by a specialist with off-road experience is recommended following installation. Rock Krawler Suspension is based in the northeastern United States, where all products are designed, engineered, and manufactured.
