GMC Sierra Differential Covers

Under the rear axle, GMC Sierra Differential Covers replace the factory housing cover with a part that can change both the look and the function of the differential. They also help seal in gear oil while giving the rear end a cleaner, more finished appearance.

 

Different styles can emphasize a low-profile factory look or a more custom, heavy-duty feel. Matching the cover shape, finish, and fitment to the Sierra’s rear axle setup makes it easier to narrow down the right option.

 

Related parts like GMC Sierra Drivetrain can support other rear-end upgrades, while 2019-2026 GMC Sierra Differential Covers focuses on newer truck applications. Airflow-focused changes are also available through GMC Sierra Cold Air Intakes for a separate performance look under the hood.
