This kit completely transforms how your JLU works as a system. Engineered to ensure the front and rear suspension complement each other, it delivers a balanced, predictable platform on the trail while remaining controlled and stable on the road.

The double-triangulated rear suspension provides smooth articulation with no binding and an optimized anti-squat range that keeps the tires driving into the ground for consistent traction, without excessive anti-squat that can make the vehicle feel unsettled.

Designed around true 18” coilovers, the system utilizes through-hood and through-tub shock towers to unlock maximum usable travel. This configuration allows for extreme articulation while delivering an aggressive, purpose-built stance.

All fabrication, setup, and final installation is performed in-house to ensure correct geometry, proper clearances, and long-term reliability. This is a complete, professionally installed system, not a mail-order parts kit.
