Dust Cover Gasket drive flange gasket 8 bo

The Winters Dust Cover Gasket Drive Flange Gasket 8 Bolt (MPN 5144) is an essential sealing component for high-performance differentials and limited-slip units that demand precision engineering. This gasket seals the critical junction between the drive flange dust cover and the differential housing, preventing fluid leakage and contamination ingress at one of the most vulnerable points in your drivetrain. Whether you're rebuilding a performance rear end, servicing a differential after heavy off-road use, or maintaining vintage muscle car suspension geometry, this Winters gasket ensures a factory-tight seal that won't weep or fail under sustained load.

Engineered specifically for 8-bolt differential housings, this gasket is precision-cut to match the exact bolt pattern and flange dimensions of Winters differentials and compatible OEM applications. The compact 5.8 x 5.95-inch footprint and minimal 0.25-inch thickness ensure proper seating without introducing runout or binding during assembly. Winters gaskets are manufactured to withstand extreme pressure cycles, thermal stress from extended driving, and the constant vibration inherent to performance differentials—delivering reliable sealing across thousands of miles of street and track duty. The gasket material resists gear oil degradation and maintains integrity even when exposed to synthetic lubricants, additives, and elevated operating temperatures.

This gasket is ideal for mechanics and enthusiasts performing differential rebuilds, limited-slip service intervals, or converting to Winters locking differentials on performance vehicles. Installation is straightforward—remove the worn gasket, clean the flange seating surface thoroughly with solvent, and position the new gasket before torquing the 8 bolts to manufacturer specifications in a cross pattern. Proper surface preparation is critical; any residual debris or old gasket material will compromise the seal and lead to weeping. Compatible with all Winters 8-bolt differential housings, this gasket is a non-negotiable maintenance component for anyone serious about keeping their drivetrain sealed and performing at peak efficiency.
