2007-2013 GMC Sierra Differential Covers

Aluminum housings fall under 2007-2013 GMC Sierra Differential Covers that protect gears on your Sierra. Finned designs dissipate heat while magnetic drain plugs capture metal particles during oil changes.

 

Cover features include cooling fins being effective or smooth versions maintaining clean appearance. Capacity options vary with standard holding stock volume or deep versions increasing oil during towing.

 

Aftermarket differential covers with cooling fins and increased fluid capacity help keep gear oil from overheating when you’re towing heavy trailers up long mountain grades. That extra cooling matters because once gear oil breaks down from heat, it stops protecting the gears properly and failures get very expensive very fast. Spending a little more on a quality diff cover is far cheaper than rebuilding a differential that cooked itself, and the peace of mind is worth it when you’re working the truck hard. To see how everything ties together, the complete 2007-2013 GMC Sierra Drivetrain catalog covers everything from axles to driveshafts. Power is managed upstream by 2007-2013 GMC Sierra Transmission & Transfer Case components, while 2007-2013 GMC Sierra Exhaust Systems help free up power and add a more aggressive sound.
