In this review the author looks at the 3.5in front and 3in rear full leveling lift kit designed for 2007-2024 Silverado 1500 and Sierra 1500 models. The bottom line: this kit is for truck owners who want a modest, factory-friendly lift that retains original shocks and uses high-quality machined components to minimize fuss. The kit's single biggest selling point is its combination of CNC-forged 6061-T6 aluminum spacers and rear shock extensions that allow owners to keep the factory shocks while achieving a 3.5in front and up to 3in rear lift.

Who It's For

This kit targets Silverado and Sierra owners who want a moderate level lift for improved clearance and a level stance without replacing factory shocks. It suits DIY mechanics and professional installers who appreciate precision CNC components and want to avoid the cost of full-length replacement shocks.

Owners seeking extreme lifts, custom long-travel setups, or who need a factory-exact ride height for towing heavy loads should look at larger suspension systems or full replacement shocks and upper control arms tailored to bigger lifts. The kit also recommends replacing upper control arms when used with 2-4in lifts, so budget accordingly.
