The Fabtech K1015 is engineered for the 2001-2006 GM C/K2500HD and C/K3500 non-dually models, providing a robust 8-inch lift that enhances both ground clearance and ride quality. This system integrates a one-piece cast drop-down steering knuckle with heavy-duty, high-arched lower control arm crossmembers made from 1/4-inch thick material, along with tubular upper control arms to ensure durability and performance.
With this setup, you can confidently fit 37-inch tires without the need to adjust the torsion bars. The front differential is strategically relocated to mitigate front driveshaft vibrations on stock driveshafts for 2001-2006 models. For late model 2007-2008 vehicles equipped with Magna 1625 transfer cases, a CV front driveshaft is required for optimal high-speed 4WD operation.
The tubular upper control arms are designed to fit into the factory frame pockets, utilizing urethane bushings for improved articulation. These arms also feature double shock mounting tabs, allowing for compatibility with Fabtech's optional front dual shock hoop system. The front suspension is further reinforced with a differential skid plate, tubular crossmember supports, and impact struts, while the torsion bar drop-down brackets align the torsion bars precisely with the relocated lower control arms.
On the rear, the system utilizes a 4-inch block kit combined with 2-inch add-a-leafs to achieve the desired lift. Additional components include rear bump stop brackets and a rear driveshaft carrier bearing drop bracket for enhanced stability and performance.
This suspension system is specifically designed for:
