A-Premium 10.25" Rear Differential Cover for Ford 12-Bolt — Stamped Steel with Gasket & Magnet

A-Premium's 10.25 inch rear differential cover is a direct-fit replacement for select Ford models, supplied with a gasket and internal magnet for cleaner gear oil and reliable rear-axle protection.

This heavy-duty stamped steel differential cover is built to match the 10.25" ring gear housing with a 12-bolt pattern used across many Ford trucks, vans and SUVs. It ships with a pre-cut gasket and includes an internal magnet to capture metal debris; bolts are not included. The cover is a practical service part when repairing, upgrading, or refreshing your rear differential during routine maintenance.

Which Ford models and years will this A-Premium cover fit?

The cover is specifically designed for axles that use a 10.25" ring gear and a 12-bolt flange. It fits a wide range of Ford Super Duty, F-series, E-series, Excursion and Lincoln Mark LT vehicles across model years from the 1980s through 2020, but compatibility depends on axle type and options like single or dual rear wheels.

• Compatible with 10.25" ring gear assemblies only (not 9.75" or 8.8").
• 12-bolt hole pattern required—does not fit 10-bolt housings.
• Common fits: F-250/F-350 Super Duty (various years), F-150 (2000–2008), E-350 vans, Excursion 2000–2005, and Lincoln Mark LT 2006–2008.

How does this cover help during differential service?

When changing gear oil or inspecting ring-and-pinion components, this replacement cover provides a sealed repair solution and helps trap metal particles that wear away from gears. Using the provided gasket ensures a leak-resistant seal when installed with the correct torque sequence and proper bolts (sold separately).

• Includes a molded gasket for an immediate seal at installation.
• Internal magnet captures ferrous shavings to reduce contamination risk.
• Stamped steel construction offers durable protection for the axle housing.

What should I check before ordering this axle cover?

Confirm your axle ring gear diameter and bolt count before purchasing to avoid fitment issues. Also verify wheel-configuration specifics (single vs. dual rear wheel) and any factory options like heavy-duty towing packages, which can affect compatibility.

• Measure ring gear or verify axle spec is 10.25" diameter.
• Count the flange bolt holes—this cover requires 12 holes.
• Check service manual or OEM part numbers (e.g., E5TZ-4033A references) for cross-reference.

Are bolts, hardware, or additional parts included?

The package includes the stamped steel cover, gasket, and internal magnet but does not include cover bolts or differential fluid. For a complete service job you will need the correct grade and length of bolts for a 12-bolt differential flange plus the specified gear oil for your axle.

• Gasket included; bolts and gear oil are not included.
• Reference numbers supplied for part matching and aftermarket cross-checks.
• Packaged in a protective box to prevent shipping damage.

Who is this for: This A-Premium 10.25" rear differential cover is intended for DIY mechanics, independent shops and fleet technicians working on compatible Ford trucks, vans and SUVs that use a 10.25" ring gear with a 12-bolt flange. Choose this cover when you need a direct-fit replacement with a gasket and magnet for routine differential service, axle repairs, or when refreshing the differential housing during restoration projects.
