The Rock Krawler JL35AXPNL-4TR is a 3.5-inch Adventure-X PRO No Limits Long Arm Trail Runner Suspension System engineered as the ideal balance between daily street driving and hardcore off-road performance. Designed and manufactured in the USA, this complete long arm lift system transforms the way your JL Wrangler handles both on the pavement and on the trail.
The Adventure-X system architecture combines a full high-clearance 4-link long arm front suspension with a high-clearance independent 3-link long arm rear suspension, delivering optimized geometry for maximum articulation and on-road stability. The X2 rear suspension geometry features enhanced rear instant centers and roll centers, making it one of the smoothest-riding 3-link setups available for the JL platform.
The "PRO" designation means all four lower control arms are CNC-machined billet aluminum — service-free, maintenance-free, and built for abuse. No greasing, no downtime. Rock Krawler's proprietary Adventure Series joints at the frame connections isolate harsh road vibrations while providing high misalignment capability and a steel-sleeved, Teflon-lined inner bore for long-term durability.
The "No Limits" feature includes specially engineered front sway bar links designed to work in conjunction with the factory electronic sway bar disconnect found on Rubicon models. The links feature factory-sized hardware, a CNC machined billet aluminum center section, and Made-in-USA FK Bearing heim joints — so Rubicon owners can press the button and hit the rocks without compromise.
The "Trail Runner" configuration includes Rock Krawler's 2.625-inch coilover shocks front and rear, adding an additional level of tunability and performance for owners who demand the most from their suspension on demanding terrain. High-clearance axle mounts deliver 3.5 inches of additional ground clearance under the rear axle versus stock, and rear upper shock relocation brackets preserve full shock and suspension travel.
Rock Krawler also backs all hard parts — control arms, track bars, and mounting brackets — with their Abuse-Proof Lifetime Guarantee, replacing any component that is bent, broken, or damaged in a way that affects function.
