Product Details

Features

  • Fiber differential cover gasket for Dana 80 rear axle housings, 10-bolt cover pattern
  • Dana 80 uses a 10-bolt cover with a 12-bolt ring gear — confirm both specs before ordering
  • Fiber construction compresses evenly against the cover sealing rail to prevent gear oil leaks
  • Sold individually; no hardware, cover, or drain plug included

Description

This is a fiber differential cover gasket sized and punched for Dana 80 rear axle housings with a 10-bolt cover pattern. It's a direct replacement for a leaking, damaged, or missing cover gasket on compatible Dana 80 axle applications, providing a reliable fiber seal between the differential cover and the axle housing sealing rail during cover reinstallation, fluid changes, or cover upgrades.

The Dana 80 uses a 10-bolt cover pattern with a 12-bolt ring gear — both specs should be confirmed against your axle before ordering, since the cover bolt count and ring gear bolt count differ and are often referenced independently when cross-shopping gaskets. This axle is commonly found in Ford F-350, F-450, F-Super Duty, Dodge Ram 2500, and Ram 3500 heavy-duty truck applications.

This gasket is sold individually and includes no hardware, cover, or drain plug. Confirm your axle model, cover bolt pattern, and sealing surface condition before installation.

 

Fiber Gasket Cut for the Dana 80's 10-Bolt Cover Pattern
This fiber differential cover gasket is punched to match the 10-bolt cover pattern used on Dana 80 rear axle housings, giving you a clean, leak-resistant seal between the differential cover and the axle housing sealing rail during cover reinstallation or replacement.

10-Bolt Cover, 12-Bolt Ring Gear
The Dana 80 is unique in that it uses a 10-bolt cover pattern alongside a 12-bolt ring gear — the two counts differ, which can cause confusion when cross-referencing specs. This gasket is built to the Dana 80's 10-bolt cover pattern specifically. A worn, crushed, or damaged cover gasket is one of the most common causes of gear oil seepage at the rear axle on heavy-duty truck applications — this fiber gasket helps restore a consistent seal.

Q&A

What axle does this gasket fit?
This differential cover gasket is designed for Dana 80 rear axle housings with a 10-bolt cover pattern, commonly found in Ford F-350, F-450, F-Super Duty, Dodge Ram 2500, and Ram 3500 applications.

Why does this listing show a 10-bolt gasket for the Dana 80 if it has a 12-bolt ring gear?
That's correct. The Dana 80 uses a 10-bolt differential cover and a 12-bolt ring gear. This gasket is designed to fit the 10-bolt cover pattern.

Will this fit a Ford F-350 or F-450?
Yes. The Dana 80 rear axle was commonly used in Ford F-350, F-450, and F-Super Duty applications. Verify your specific axle before ordering.

Will this fit a Dodge Ram 2500 or 3500?
Yes. The Dana 80 rear axle was commonly used in many Dodge Ram 2500 and Ram 3500 models. Confirm your axle before purchasing.

Will this fit a GM rear axle?
No. This gasket is designed specifically for Dana 80 10-bolt differential cover applications and is not compatible with GM axle assemblies.

Do I need to use RTV with this gasket?
Fiber gaskets can be installed with or without RTV sealant, depending on the condition of the sealing surfaces and your preferred installation method. Always clean both mating surfaces thoroughly before installation.

What's included with this gasket?
This listing includes the fiber differential cover gasket only. Differential cover, mounting hardware, and drain plug are not included.

When would I need to replace my differential cover gasket?
A new gasket is recommended whenever the differential cover is removed for gear oil changes, inspections, repairs, or differential cover replacement to help prevent leaks.

Does this gasket work with aftermarket differential covers?
Yes, provided the aftermarket cover is designed for the Dana 80 10-bolt axle and uses the factory sealing surface and bolt pattern.

How do I ensure a proper seal with this gasket?
Thoroughly clean the differential housing and cover sealing surfaces, remove all old gasket material and sealant, position the gasket correctly, and tighten the cover bolts evenly to the manufacturer's specifications.
