Rear Axle Housing Seals for Small Bearing 31 Spline Axles | Pair | 66-75 Ford Bronco SKU: 8632

Rear Axle Housing Seals for Small Bearing 31-Spline Axles | 66–75 Bronco

Not factory replacements—these custom rear axle housing seals are designed exclusively for use with 31-spline axle conversions in small bearing rear housings found on 1966–1975 Ford Broncos. If you've already upgraded your rear end with 31-spline axles and need to replace a damaged or worn seal from that setup, this is the part you're after.

These seals are not compatible with stock axle setups and are only intended for those running 31-spline small bearing axles.

• Upgrade-Specific Fitment – Not for stock applications; designed for 31-spline axles in small bearing housings only.

• Replacement for Modified Setups – Ideal for replacing worn or damaged seals from previous axle upgrade kits.

• Restoration Support – A must-have if your upgraded rear end is leaking or due for a refresh.

If you're running upgraded 31-spline axles in your small bearing rear end and in need of replacement axle seals, this is the part you need. Not for stock axles.
