Rock Krawler JL35X2NL-4DTR 3.5 Inch X Factor X2 No Limits Trail Runner Long Arm Suspension Kit 4-Door

The Rock Krawler JL35X2NL-4DTR is the 3.5-inch X Factor X2 "No Limits" Trail Runner Long-Arm Suspension System engineered for the 4-door Jeep Wrangler JL Unlimited platform. Purpose-built for hard-core rock crawling, this complete long-arm lift kit combines Rock Krawler's proven X Factor independent 3-link geometry with the Trail Runner coilover shock package for a fully tunable, trail-ready suspension system.

The "No Limits" designation refers to the inclusion of Rock Krawler's purpose-built front sway bar links, designed specifically to work with the factory electronic sway bar disconnect feature found on Rubicon models. The sway bar links feature factory-sized hardware, a CNC-machined billet aluminum center section, and Made in USA FK Bearing heim joints — simply press the button and hit the rocks.

The X Factor X2 long-arm architecture delivers an independent 3-link design front and rear for maximum suspension articulation and off-road performance. Double-adjustable upper control arms front and rear upsize the factory hardware to 14mm with 2-3/8" mounting width and 1" Pro Krawler joints at each end. The rear suspension geometry provides adjustable anti-squat with enhanced rear instant center and rear roll center positioning.
