After Dark Speed 97-04 C5 Corvette Hi-Performance Adjustable Rear Diff Mount Kit

After Dark Speed 97-04 C5 Corvette Hi-Performance Adjustable Rear Diff Mount Kit

High-performance, lightweight direct replacement adjustable rear differential mount kit for 1997-2004 C5 Corvettes, including Z06 models.

This mount is designed for performance street, autocross, and track day applications where additional rear differential support is needed without stepping all the way into the harshness of a solid mount setup.

The design still uses bushings, but they are smaller and firmer than the large factory rubber isolator. This provides a strong balance between vibration damping and reduced driveline movement.

Adjustable Differential Height

The mount assembly comes pre-assembled to position the rear differential at the original factory height. It also includes a unique slug system that allows the differential to be lowered in 1/8 inch increments, up to a maximum of 1/2 inch lower than stock.

This adjustment can help create additional clearance for aftermarket exhaust systems while also lowering the vehicle’s center of gravity.
