This system levels the Silverado 2500 HD's stance and improves ride quality with premium-grade components designed for extreme environments and aggressive aesthetics.
Construction and Appearance. Featuring precision-built 4130 Chromoly Uniball upper control arms, this kit is engineered to reduce flex and provide superior suspension strength. Fabtech's stainless steel, PTFE-lined 1-inch Uniballs deliver extended articulation and reliability in rugged terrain. Dirt Logic 2.25 reservoir shocks, constructed with stainless steel bodies and NitroSteel rods, offer consistent performance and enhanced cooling via remote aluminum reservoirs. The entire system is crafted for long-term durability with .250 wall DOM bushings and forged torsion bar keys to further optimize lift height.
Installation. This kit is designed for a straightforward bolt-on installation with no modification to the spindle, thanks to the factory-compatible Uniball pin. Professional installation is recommended due to the complexity of aligning caster and suspension geometry properly.
