Hub Gasket For 5x5

The HOWE Hub Gasket For 5x5 (part number 20550) is a precision drive flange gasket engineered for high-performance axle assemblies and off-road vehicle applications. Designed to maintain a reliable seal between the hub and drive flange, this gasket prevents fluid leakage and contamination at the critical junction where rotational forces are greatest. With an outer diameter of 3.975 inches and inner diameter of 3.51 inches, it accommodates the 5x5.00 / 4.75-inch wheel bolt pattern common to heavy-duty trucks, buggies, and specialized off-road platforms.

The gasket's 0.065-inch thickness is calculated to provide optimal compression and sealing force without introducing binding or misalignment. Proper gasket selection is critical in axle assemblies—undersized or improperly seated gaskets invite differential fluid weeping and premature bearing wear, especially under sustained off-road operation or high-speed highway driving. This HOWE gasket maintains dimensional consistency across cycles, resisting deformation from thermal cycling and vibration that plague lower-grade alternatives. The 5x5 bolt pattern appears on Howe and other premium performance axle housings commonly found in rock crawlers, dune buggies, and high-output truck builds.

Technicians and builders tackling axle rebuilds, seal replacements, or component upgrades rely on OEM-equivalent gaskets like this to ensure zero-leak performance. Whether you're servicing a Howe differential for racing duty or maintaining an off-road platform for backcountry reliability, having the correct gasket on hand eliminates field improvisation and guarantees proper sealing geometry. Each gasket is sold individually, allowing builders to stock the exact specification required for their assembly.
