Take Your Silverado Or Sierra From Stock To Serious

If you’re looking to lift your 2025 Silverado or Sierra 1500 4WD and give it the clearance and attitude it deserves, the Fabtech K1220 6" Lift Kit is ready to get it done. This setup instantly transforms your truck with a full six inches of front lift and a five-inch lift in the rear, making room for larger tires and a more commanding presence. Whether you're tackling backroads, navigating rough job sites, or just want that extra height for daily driving, this system delivers a clean, factory-style look while packing serious off-road potential. Fabtech’s reputation for ride quality shows here too, the rear performance shocks offer solid damping without giving up comfort. The near-stock track width keeps the tires tucked under the fenders, so you maintain a streamlined, street-legal stance. This system is made to go on clean, with no weird geometry issues or unexpected handling changes. It’s a well-rounded upgrade for the truck owner who wants to step things up without stepping too far from daily drivability.

Engineered Suspension Geometry That Balances Lift And Control

The Fabtech K1220 6" Lift Kit is engineered specifically for 2025 GM Sierra and Silverado 1500 4WD models with crew cab and short bed configurations. It features Fabtech’s industry-leading IFS suspension design, built around quarter-inch thick steel crossmembers and OE-style cam pins for precise alignment after installation. Up front, the factory coilovers are relocated using shock spacers to achieve lift without limiting steering travel or compromising ride quality. The triple differential mount system repositions the front diff to eliminate driveline vibration at higher speeds. In the rear, Fabtech uses a 5-inch block and round-style U-bolt setup combined with their performance twin-tube shocks to maintain damping control and comfort. The system is designed with a zero bump steer layout and proprietary knuckle geometry that preserves lock-to-lock steering while improving maneuverability in tight areas. This kit is not compatible with AT4, Trail Boss, Super Cruise, or magnetic ride control models, and it does require aftermarket wheels due to factory wheel clearance limitations. Every element of this kit is tuned for strength, stability, and real-world reliability, both on and off the road.
