Product Description

The Fabtech K1212M lift kit delivers a balanced, moderate 3" front / 1.5" rear lift for 2019-2025 Silverado and Sierra 1500 trucks, ideal for owners seeking more ground clearance, larger tire accommodation, and a more aggressive stance without sacrificing drivability. The included heavy-duty ball-joint UCAs provide extended suspension travel and prevent binding at full droop - preserving suspension geometry and alignment potential even after lift. By using spacers with the factory front coil-overs, the kit helps retain a relatively smooth, OEM-like ride feel up front.

In the rear, 1.5" lift blocks combined with Stealth monotube shocks improve handling under load and better manage the altered suspension geometry. This setup offers improved off-road capability, more clearance for larger wheels/tires (up to ~33" with proper wheel specs), and a cleaner, lifted appearance. The bolt-on design means installation is simpler than full suspension swaps - and the kit is reversible, allowing return to stock if needed. For Silverado/Sierra 1500 owners wanting a practical, street-friendly lift that opens up upgrade potential, K1212M is a solid, well-rounded upgrade.
