A-Premium 8.8in Ring Gear Rear Differential Cover Black — Stamped Steel with Magnet & Gasket

The A-Premium 8.8" ring gear rear differential cover is a heavy-duty steel replacement that seals your axle housing, traps metal debris with an internal magnet, and includes a gasket for a secure, leak-resistant fit.

How does the magnet and gasket improve performance?

The built-in magnet gathers metallic shavings that circulate in the gear oil, helping keep bearings and gears cleaner between services. The supplied gasket creates a consistent seal against the axle housing to reduce leaks and simplify installation.

• Internal magnet collects ferrous debris for cleaner lubricant
• Factory-style gasket included for reliable sealing
• Stamped-steel construction resists denting and warping under normal use
• 10-bolt flange matches OEM bolt pattern for straightforward replacement

Is installation complicated and what tools are needed?

Installation is straightforward for anyone comfortable servicing differential components; it requires standard hand tools and proper torqueing of bolts. Drain the gear oil, remove the old cover, clean the mounting surface, fit the new gasket and cover, then refill with the correct gear oil volume and type for your vehicle.

• Basic tools: socket set, torque wrench, drain pan, gasket scraper
• No filler plug included — use vehicle-specific fill/drain process
• Follow torque specs from your service manual to avoid leaks
• Inspect the magnet and clean during routine oil changes
