Rock Krawler 2018+ Jeep Wrangler JL 2DR 4.5in Adventure-X Pro Long Arm Coilover Suspension

The Rock Krawler 4.5" Adventure X2 PRO ELITE COILOVER Long-Arm Suspension System offers a superior blend of daily driving comfort and extreme off-road capability. This system features billet aluminum CNC machined service-free lower control arms and combines a high-clearance 4-link front suspension with an independent 3-link rear suspension. The Adventure series joints are maintenance-free and provide high misalignment with a steel sleeve on a Teflon-lined inner sleeve, effectively isolating road vibrations for a smoother ride. The X2 rear suspension geometry is specifically designed to enhance ride quality.

This comprehensive suspension system includes a weld-on front long-arm mounting system, heat shield products, a front adjustable anti-wobble track bar, four billet 7075 lower control arms, and four adjustable upper control arms. For the rear, it provides weld-on frame side long arm mounts, a rear upper control arm, a rear frame side upper control arm mount, extended sway bar links, an adjustable anti-wobble track bar, weld-on rear upper shock mounts, and a weld-on rear axle truss. The system also includes rear brake line relocation brackets. Depending on the chosen shock package, front upper shock mounts, rear triple-rate coil springs (COMP Systems), and rear spring correction seats (COMP Systems) may also be included.

Shock options for this system feature RRD 2.625" RR Coilover Shocks or RRD 2.625" FCD Coilover Shocks with Fast CD Adjustability, available in both COMP (Coilover Front/Coil Spring Rear) and Trail Runner (Coilover Front and Rear) configurations. These shocks are designed and built in-house by Rock Krawler. The system provides significant rear clearance gain from the X2 Axle Bracket System and adjustable rear anti-squat with X2 Geometry. It is backed by a lifetime warranty.

Wheel and tire fitment recommendations vary based on the Jeep Wrangler JL submodel. For Sport and Sahara models, 37"/38" tall tires are recommended with 3.5" backspacing, while Rubicon models can accommodate 37" tall tires with 4.5" backspacing or 40" tall tires with 3.5" backspacing. General notes suggest that lift heights are based on Rubicon models with standard builds (front bumper and winch, rear bumper, full-size spare). Adjustments for XR Package, spare delete, or heavily upfitted builds are also detailed. A new front C.V. driveshaft is recommended for all models.
