How does this cover protect the differential?

The stamped steel casing restores a sealed reservoir for gear oil and replaces a damaged or leaking original cover. Its internal magnet captures ferrous metal particles before they circulate, and the included gasket helps prevent fluid leaks at the mating surface. While it doesn’t include a filler plug, the cover maintains factory bolt alignment for a secure seal.

• Internal magnet traps metal shavings that can accelerate wear
• Steel construction resists impact and provides a durable barrier
• Includes a pre-cut gasket for a leak-resistant installation
• Uses the OEM 10-bolt pattern for straightforward replacement

Will I need any special tools or parts to install it?

Installation is straightforward for anyone comfortable with basic axle service and hand tools. You’ll need to drain the differential fluid first, remove the old cover bolts, clean the flange surface, and torque the new bolts to the manufacturer's spec. If your axle originally used a filler plug, you may want to source the correct plug separately before refilling.

• Basic tools: socket set, torque wrench, gasket scraper, drain pan
• Replacement fluid (type and volume per vehicle service manual)
• Optional: thread sealant for drain/filler plug if you add one
• Check factory torque specs for the 10 cover bolts

What are the product specifications and warranty?

The cover is made from stamped steel with a black finish and fits 8.8" ring gear axles using ten bolts. It ships with a gasket but does not include a filler plug. A-Premium backs the product with a one-year unlimited-mileage guarantee to cover workmanship and fitment issues.

• Material: stamped steel; Finish: black
• Gasket included; filler plug not included
