Hub Seal Wide 5

The Hub Seal Wide 5 from ALLSTAR PERFORMANCE is a precision inner hub bearing seal engineered for Wide 5 wheel applications, commonly found on classic hot rods, street machines, and vintage racing builds. This component seals the critical interface between the hub and bearing assembly, preventing contamination from dirt, moisture, and debris while retaining vital lubricant. Whether you're restoring a classic muscle car or maintaining a custom hot rod, a quality hub seal is essential to protect bearing longevity and ensure safe wheel operation.

Constructed from a durable rubber and steel composite, the Hub Seal Wide 5 features a lip-style design that creates a dynamic seal against shaft runout while accommodating minor misalignment common in vintage suspension setups. With an outer diameter of 3.48 inches, an inner diameter of 2.375 inches, and a thickness of 0.438 inches, this seal is engineered to fit the specific geometry of Wide 5 rear hub assemblies. The lip configuration actively wipes contaminants while the steel backing provides structural support and prevents extrusion under operating pressure and temperature cycling.

Mechanics and hot rod builders rely on the Hub Seal Wide 5 for rear axle assembly work, particularly when refreshing bearing packs on classic vehicles or custom wheel installations. Installation is straightforward—the seal presses into the rear hub pocket during assembly—and replacement is recommended whenever bearings are serviced or hubs are disassembled. This single seal protects your entire rear bearing investment, making it an economical and critical maintenance item for any Wide 5 application.
