Restore Factory Ride Height on Your Classic GM Heavy Half
The Skyjacker C124BS suspension lift component gives owners of vintage GM three quarter and one ton trucks a reliable way to dial in ride height and clearance. Built for the 1987 GMC V2500 and a wide range of related K20, K25, and K2500 platforms from the 1970s and 1980s, this component box delivers the mounting hardware and structural pieces needed to complete a proper lift installation. Skyjacker engineered the C124BS to work with factory geometry, so steering and drivetrain angles stay within a safe range after installation. For a truck that has been sitting low or riding rough, the C124BS is a straightforward path back to a leveled stance.
