Rock Krawler JL35X2PNL-4DS1 3.5-Inch X Factor X2 Pro No Limits Long-Arm Suspension Lift Kit Stage 1

The Rock Krawler JL35X2PNL-4DS1 is the 3.5-Inch X Factor X2 Pro "No Limits" Long-Arm Suspension System Stage 1, engineered for Jeep Wrangler JLU 4-door owners who demand serious hard-core rock crawling performance without compromising street manners.

X Factor X2 Long-Arm Architecture:

• Independent 3-link design front and rear for maximum suspension articulation and off-road performance
• Double-adjustable front and rear upper control arms that upsize factory hardware to 14mm with 2-3/8" mounting width and 1" Pro Krawler joints at each end
• X2 rear suspension geometry with adjustable anti-squat, enhanced rear instant center, and improved rear roll center
• High-clearance axle mounts provide 4.5 inches of additional ground clearance under the rear axle compared to stock
• Rear upper shock relocation brackets ensure no loss of shock or suspension travel

"No Limits" Sway Bar System:

• Includes No Limits front sway bar links specifically engineered for use with the factory Rubicon electronic sway bar disconnect feature
• Links feature factory-sized hardware, a CNC machined billet aluminum center section, and USA-made FK Bearing heim joints
• Simply press the factory button to disconnect and achieve full suspension articulation on the trail

"Pro" Control Arm Package:

• PB&J (Pure Beef & Jealousy) billet aluminum lower control arms — custom machined in-house from solid square stock billet aluminum for maximum durability
• Maintenance-free Adventure Series joints at frame connections paired with Pro Krawler Joints at axle connections
• Full caster and pinion angle adjustability front and rear for precision geometry tuning

Triple-Rate Coil Springs & Geometry Corrections:

• Triple-rate coil springs deliver excellent on-road comfort while maintaining proper free-length for off-road articulation
• Correction pads reduce the spring bow inherent in the factory setup
• Front and rear track bar geometry corrections perfectly center both axles for no compromise in on-road handling
• Heat shield thermal barrier protection on front control arm joints at the frame, matching OEM standards

As a Stage 1 system, this kit includes shocks for a complete, trail-ready installation. The combination of long-arm geometry, high-clearance X2 rear brackets, No Limits sway bar integration, and Pro-grade billet aluminum arms makes the JL35X2PNL-4DS1 one of the most comprehensive 3.5-inch long-arm lift systems available for the Jeep Wrangler JLU 4-door platform.
