ReadyLift - 6" MAX3.3 Lift Kit w/ Falcon 3.3 Shocks & Fabricated UCA - 2020-2026 Chevy/GMC 2500/3500 HD - 42-30660

6" MAX3.3 premium suspension system with Falcon 3.3 Fast Adjust piggyback shocks and Xtreme-Duty 4130 chromoly upper control arms, built for the 2020-2026 Chevy Silverado and GMC Sierra 2500/3500 HD.

ReadyLIFT's 6" MAX3.3 system is a complete suspension upgrade engineered with precision geometry and heavy-duty construction. It pairs vehicle-specific Falcon 3.3 Fast Adjust piggyback shocks - offering independent compression and rebound tuning - with laser-cut, CNC-formed crossmembers, a full-coverage differential skid plate, OE-style cast iron knuckles with corrected geometry, Xtreme-Duty 4130 chromoly steel upper control arms with corrected ball joint angles, cast rear lift blocks, and taller fabricated torsion arm brackets. The result is an aggressive HD stance and serious capability without sacrificing drivability.

Fits: 2020-2026 Chevy Silverado / GMC Sierra 2500HD/3500HD. Single Cab configuration has not been validated for fitment and drivability by ReadyLIFT.
