4.5 Inch Adventure X2 No Limits Long-Arm Suspension System for Jeep Wrangler JLU Diesel Models With Bilstein Shocks Rock Krawler

Rock Krawler 4.5 Adventure X2 No-Limits Long-Arm Suspension System for Jeep Wrangler JLU (Diesel Models)

The Rock Krawler 4.5 Adventure - X2 No-Limits Long-Arm Diesel System is the ultimate in compromise between daily driver/hard core off-roader. The term No-Limits comes from the inclusion of our front sway bar links specifically designed for use with the factory electronic sway bar disconnect feature found standard in your Rubicon Wrangler!

The Adventure-X2 systems combine the benefits of a full high clearance 4 link front suspension with a high clearance independent 3 link rear suspension. Say goodbye to greasing your joints, our service free long-arm system is here to stay.

In every single control arm, we have our Adventure Series joint center, which isolates harsh road vibrations equivalent to an OE bushing, includes high misalignment, and is fitted with a steel sleeve (that the bolt passes through) which rotates freely on a additional Teflon lined inner sleeve to insure that you are never chafing, twisting, or deforming the bushing material inside the housing as you blast through the mud, sand, sleet, salt, snow, dirt and dust.

To finish it off, as you tighten your control arms into the mounts, the sleeve of the joint is engineered to be the buffer between the clamping force of a bracket, which means that as you tighten everything, you are not compressing the bushing. This all makes for an incredibly long lasting joint that never requires a drop of grease, and makes zero noise inside the housing.

This is where conventional on-road handling meets bad ass off-road ability. With enhanced rear instant center (s) and rear roll center (s), X2 rear suspension geometry is the smoothest riding 3-Link suspension you can take down a trail or cruise across America in your Wrangler.

The new high clearance axle mounts provide 4.5 inch of ground clearance under the rear axle as compared to stock. The rear upper shock relocation brackets ensure you do not lose any shock or suspension travel.

The combination of a full high clearance 4-link long arm front suspension and high clearance independent 3 link rear long arm suspension lets you dominate the streets and the trails.

Driving you home with the most comfortable ride possible in a Wrangler, are our Triple-Rate coils. All 4 coils work together to achieve excellent on-road comfort that we feel is better than the OEM linear rate springs.

The coil itself is built with the proper Free-length for off-road articulation and stays firmly seated in the coil bucket (as long as a proper length shock is installed), and overall has a very controlled reaction to bumps, rocks, sand, mud and whatever else you can manage to throw at them! All Rock Krawler JLU systems include correction pads that reduce the spring bow inherent in the factory setup.

When we design a system, our goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, in tow or down a trail! Thank you for considering Rock Krawler Suspension.
