Construction & Design:

Fabtech’s Radius Arm Kit is built with high-quality materials and precision engineering to withstand demanding conditions. The front coil springs utilize a straight design that lowers the spring rate compared to factory bowed springs, resulting in a smoother ride without compromising strength. The rear dual-stage coil springs adapt to load changes, offering comfort when unloaded and firm support when carrying heavy payloads.

The radius arms and mounting hardware are crafted for durability and precise fitment, ensuring long-lasting performance and alignment stability. The 2.25-inch DLSS shocks are designed to complement the coil springs by providing superior damping control, reducing harshness and improving overall ride dynamics.

Installation & Fitment:
