Differential Covers for GM 10-Bolt & 12-Bolt Axles

Stronger than stamped steel with added fluid capacity — Black Crinkle, Cast Gray, and chrome, many with a Bowtie emblem.

PROFORM differential covers add strength and style to GM 7.5, 10-bolt (8.2/8.5/8.6), and 12-bolt car rear ends. Cast aluminum construction adds rigidity and fluid capacity over a stamped-steel cover to help control heat on hard-launched and heavy-duty builds, with Black Crinkle, Cast Gray Crinkle, and chrome finishes to match the driveline. Many carry an officially licensed raised Bowtie emblem, and the Perfect Launch series adds a reinforced design for drag and street-strip use. Hardware is included for a direct bolt-on fit.
