• Compatible with 37-inch tires on wheels ranging from 17 to 22 inches with minor trimming
• Designed exclusively for diesel-powered Ram 2500 models; not compatible with gas engines
• 5-inch lift height for enhanced ground clearance and aggressive stance

Construction & Design:

Fabtech’s suspension components are crafted from high-quality materials engineered for durability and long-lasting performance. 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 springs adapt to load conditions, softening the ride when unloaded and stiffening under heavy payloads.

Performance shocks included in the kit are precision-tuned to work in harmony with the coil springs, providing superior damping characteristics that reduce harshness and improve vehicle control. The entire system is designed to withstand the rigors of off-road use while maintaining excellent on-road manners.
