Fel-Pro 55001 Drive Axle Shaft Flange Gasket

Fel-Pro 55001 is a composite drive axle shaft flange gasket built for rear axle sealing at the flange connection. It is specified for applications that need a 2-7/8 inch inside diameter and a 4-bolt-hole pattern, including Ford Bronco, Ford Mustang, Mercury Cougar, and Ford Thunderbird rear axle service.

Key Features

  • Composite gasket material for axle flange sealing
  • 2.875 inch inside diameter for the listed rear axle applications
  • 4 bolt holes for the specified flange pattern
  • Direct-fit sealing solution for rear drive axle shaft flange service
  • Fel-Pro sealing design focused on application-specific fitment

Product Details

Fel-Pro 55001 is a drive axle shaft flange gasket used at the rear axle flange where the axle shaft and housing connection must stay sealed. The composite construction supports a reliable sealing surface for service work on 1966-1968 Ford Bronco rear, 1964-1968 Ford Mustang rear, 1967-1968 Mercury Cougar rear, and 1961 Ford Thunderbird rear applications. This part number, 55001, is also referenced in cross applications such as MAHLE J26374 and Pioneer Automotive Industries 614527 or 760016.

What It Helps Address

  • Rear axle flange oil seepage
  • Leakage at the axle shaft-to-flange sealing surface
  • Damaged or flattened gasket material during axle service
  • Improper sealing after differential or axle shaft maintenance
  • Noise or contamination concerns caused by a compromised rear axle seal area

Installation Notes and Tips

Confirm the flange pattern, 2.875 inch inside diameter, and 4-bolt-hole layout before installation. Clean both mating surfaces thoroughly so the composite gasket can seat evenly, and inspect the flange for warpage, corrosion, or debris that could affect sealing. For fitment searches, this part is commonly listed for 1964-1968 Ford Mustang rear, 1966-1968 Ford Bronco rear, and 1967-1968 Mercury Cougar rear service. Verify the axle application against the vehicle before assembly.

Quality Assurance

Fel-Pro gaskets are engineered with application-specific materials to deliver vehicle sealing performance and durability that professional technicians rely on. Fel-Pro 55001 follows that sealing-focused approach for rear drive axle shaft flange service on the listed Ford and Mercury applications.
