Quick Overview

The Rancho 4" lift kit for your Dodge Ram 2500 features new heavy duty tubular-style upper and lower links which bolt directly to the OE mounting location without cutting or welding. Providing additional strength and stability to the suspension, the new links restore caster to an optimal setting. Steering integrity is uncompromised through the use of a new forged pitman arm that ensures optimal steering geometry and eliminates bump steer. Computer-calibrated, state-of-the-art coil springs enhance both ride quality and performance. No exhaust modification necessary. Allows for reuse of the OE front skid plate. Reinforced track bar relocation bracket.

Longer shocks are required and sold separately.
