Suburban 1/2 ton 1973-1991 GMC 4WD (w/4-8" Lift) - Transfer Case Drop Kit by Skyjacker

The Skyjacker TCL150 Transfer Case Drop Kit is designed to help correct driveline angles on 1973–1991 GMC Suburban 4WD models equipped with 4 to 8 inches of suspension lift. Lifting your vehicle changes the operating angle of the driveshaft, which can lead to driveline vibration, noise, premature U-joint wear, and reduced drivetrain performance.

By lowering the transfer case, the TCL150 helps restore proper driveshaft geometry and reduce the operating angle between the transfer case and driveshaft. This simple yet effective solution minimizes driveline vibrations while promoting smoother operation and improved drivetrain reliability after installing a suspension lift.

Whether you're completing a new lift installation or correcting vibration issues on an existing setup, the Skyjacker Transfer Case Drop Kit is an effective way to improve driveline performance while maintaining dependable operation both on and off the road.
