Rock Krawler 4.5" Adventure X Mid-Arm Suspension System for 18-26 Jeep Wrangler JL 2-Door Sport

Starting at
$2,600.88
Description

Tire Capability (Up to 37"): This is one of the few mid-arm systems that safely clears 37-inch tires on a 2-door JL (with appropriate trimming or high-line fenders). It provides the height needed for maximum pumpkin clearance and a truly aggressive stance.

Indestructible Adventure-X Components: The control arms and track bars are made from solid bar stock, not hollow tubing. This makes them significantly more durable for rock crawling, and they are backed by an "Abuse It" lifetime warranty—if you break it on a trail, it’s covered.

Refined Short-Wheelbase Handling: Lifting a 2-door 4.5 inches is usually a recipe for a harsh ride, but the triple-rate coils provide a plush initial stroke for road bumps. This ensures your "weekend toy" doesn't become a nightmare to drive to the trailhead.

Maintenance-Free Articulation: The Adventure Series joints offer up to 70 degrees of misalignment for incredible flex, yet they use a specialized bushing that requires zero greasing. You get the performance of a spherical race-joint with the quiet, service-free life of an OE bushing.

Complete Geometry Correction: At this height, driveline and steering angles are critical. By including all eight adjustable arms, this kit allows you to perfectly align the Jeep, preventing the "flighty" steering and vibrations that often plague taller 2-door lifts.

Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.

Details

The Rock Krawler 4.5" Adventure-X Mid-Arm System for the 2-door Jeep Wrangler JL is a serious "big lift" setup designed for enthusiasts who want to dominate the most technical trails. On a 2-door JL, a 4.5-inch lift provides massive ground clearance, allowing you to easily run 37-inch tires while drastically improving your breakover angle to clear the sharpest peaks without high-centering. The "Adventure-X" package is the centerpiece here, providing all eight adjustable control arms made from 1.75-inch solid alloy steel, which are nearly twice as strong as the factory units and designed to take direct impacts from rocks without bending.

Because lifting a short-wheelbase 2-door this high can drastically affect stability, Rock Krawler utilizes triple-rate coil springs and corrected geometry to keep the Jeep manageable. The 4.5-inch springs provide a long "free-length" to ensure the coils stay seated during extreme articulation, while the adjustable mid-arms allow you to precisely reset your caster and pinion angles to maintain a stable, "one-finger" steering feel on the highway. This system also includes an adjustable heavy-duty front track bar and a rear relocation bracket, ensuring your axles are perfectly centered and your roll center is optimized to reduce the "tippy" sensation common with tall 2-door builds.
