Rock Krawler JL35AX2NL-392TR 3.5 Inch Adventure-X2 No Limits Trail Runner Long Arm Suspension System 392

The Rock Krawler JL35AX2NL-392TR is a 3.5-inch Adventure-X2 "No Limits" Trail Runner Long Arm Suspension System engineered specifically for the Jeep Wrangler JL 392 platform. This system delivers an ideal balance between a comfortable daily driver and a capable hardcore off-road build, with every component purpose-built to handle the weight and power of the 392 cubic inch V8 engine.

392-Specific Triple-Rate Coil Springs:

This system features 392-specific Triple-Rate coil springs that achieve 3.5 inches of lift over the factory 1-inch ride height. The heavier spring rate is engineered to account for the added mass of the V8 drivetrain, delivering a balanced and functional lift while maintaining excellent on-road ride quality that surpasses OEM linear-rate springs. The coils are built with the proper free-length for maximum off-road articulation and remain firmly seated in the coil bucket throughout the suspension travel range.

Key Features:

• Adventure-X2 Long Arm Geometry — Combines a full high-clearance 4-link front suspension with a high-clearance independent 3-link rear suspension for superior articulation and on-road handling
• "No Limits" Sway Bar Links — Specially designed front sway bar links compatible with the factory electronic sway bar disconnect feature, featuring CNC machined billet aluminum center sections and USA-made FK Bearing heim joints
• Service-Free Control Arms — 100% maintenance-free Adventure Series joints eliminate the need for regular greasing
• Triple-Rate Coil Springs — 392-tuned coil springs provide a controlled reaction across all terrain types including rocks, sand, and mud
• Correction Pads Included — Reduces the spring bow inherent in the factory JL setup for improved geometry
• Track Bar Geometry Corrections — Front and rear corrections allow precise axle centering with no compromise to on-road handling
• Trail Runner System — Stage-level shock and suspension package optimized for trail use
• High Clearance Axle Bracket System — Provides significant ground clearance gains under the rear axle compared to stock

Installation Notes: This long arm system requires welding of the front and rear long arm mounts, removal of OEM frame-side lower front and rear control arm mounts, removal of OEM frame-side front and rear upper control arm mounts, removal of OEM axle-side rear lower control arm and track bar mounts, and modification and welding of the raised rear upper shock mounts. A new front CV driveshaft is recommended if front shock extended length exceeds 29 inches.

All lift heights are based on standard Rubicon 392 builds with a front bumper and winch, rear bumper, and full-size spare. Rock Krawler backs all hard parts with their industry-leading abuse-proof lifetime warranty.
