CST Suspension is an industry leader in the design and construction of IFS lift systems for GM HDs. This CST kit is extensive, using precisely fit, MIG-welded drop brackets, a special steering drop system featuring Heim joints, and a full array of Grade 8 fasteners. Of special note is CST's main engine cradle. It's a fully welded component that is designed to enhance the structural integrity of the OE frame and is further strengthened with the installation of longitudinal cradle-to-frame struts. The CST kit delivers 9-inches of lift on a 1500 or 2500-Series HD, but you'll likely want to install CST's 4-inch lifted spindles to complement the lift kit.

Cognito Motorsports takes great pride in the fact that its 10- and 12-inch suspension systems for GM 4WD IFS trucks is a true bolt-on. Cognito took special care to manufacture a kit that retains all of the factory steering, suspension, and alignment geometry, while still delivering a massive lift, thanks to fully welded suspension drop components and the rugged engine cradle. The Cognito suspension lift was designed to make the installation process a straightforward affair and as such uses as many factory mounting holes as possible. The kit is furnished complete in every regard. Cognito claims there will be no unexpected surprises or costs involved with the kit's installation.
