Hub Seal Wide 5 Low Drag

The Hub Seal Wide 5 Low Drag from ALLSTAR PERFORMANCE is a precision-engineered bearing seal designed for high-performance rear axle assemblies on Wide 5 hub configurations. Built for enthusiasts and professional mechanics who demand minimal rotational resistance without compromising bearing protection, this inner seal is essential for drag racing, circle track, and street performance applications where every tenth of a second—and every fraction of a horsepower—counts. The low-drag design reduces parasitic losses in the drivetrain, allowing power to reach the wheels more efficiently than traditional seals.

Constructed from a durable rubber and steel composite, the Hub Seal Wide 5 Low Drag features an O-ring design with a 3.48-inch outer diameter and 2.375-inch inner diameter, delivering a 0.438-inch thickness optimized for Wide 5 rear hubs. The low-drag geometry minimizes contact pressure against the rotating hub while maintaining an effective seal against contaminants and fluid loss. This engineering balance is critical: standard seals increase rolling resistance and heat generation, whereas this design sacrifices nothing in protection while reducing friction that would otherwise be converted to wasted energy and unwanted temperature rise in the bearing assembly.

This seal is ideal for racers and weekend warriors running Wide 5 rear axles on street rods, circle track cars, and dedicated drag vehicles where bearing longevity and consistent performance matter equally. Installation is straightforward for any mechanic familiar with rear axle service; the O-ring design ensures a reliable fit and proper sealing without complex machining. Each unit is sold individually, making it simple to replace one or both sides of the axle assembly during a bearing refresh or preventive maintenance cycle. Compatible exclusively with Wide 5 hub configurations, this ALLSTAR PERFORMANCE seal delivers measurable improvements in efficiency and thermal management over conventional designs.
