Hub Seal Wide 5 Air Gap Billet Aluminum

The DRP Performance Hub Seal Wide 5 Air Gap Billet Aluminum is a precision-engineered wheel hub seal designed for vehicles equipped with Wide 5 lug pattern hub assemblies. This outer lip-style seal combines a 3.48-inch outer diameter with a 2.385-inch inner diameter and 0.372-inch thickness, delivering a sealed bearing assembly solution that prevents contaminant ingress while managing air gap clearance. Constructed from aluminum with a PTFE (polytetrafluoroethylene) contact surface, this seal is engineered to handle the thermal and rotational demands of high-performance applications where hub integrity directly impacts wheel assembly longevity.

The air gap design distinguishes this seal from solid contact alternatives. By maintaining a controlled space between seal and surface, the Wide 5 hub seal minimizes friction heating and reduces drag on hub bearings—a critical advantage in sustained-use scenarios such as long-haul driving or high-speed track work where bearing temperature management affects reliability. The PTFE lip material resists abrasion and maintains consistent contact pressure across thermal cycling, ensuring seal performance doesn't degrade as operating temperatures fluctuate. At just 0.18 lbs, the aluminum construction provides lightweight design without sacrificing structural integrity, making this seal suitable for both street and performance-oriented platforms.

This seal addresses the needs of Wide 5 hub users—primarily classic American vehicles, certain performance platforms, and specialty applications—who require OEM-spec or upgraded hub seal replacement. Mechanics and restoration specialists rely on precise bore and diameter matching to ensure proper installation and seal function. The DRP Performance specification ensures compatibility with Wide 5 hub configurations where bearing preload and seal clearance are critical to avoiding premature wear or bearing failure. Whether you're rebuilding a hub assembly, addressing a seal leak, or upgrading to a higher-performance bearing setup, matching the exact seal dimensions and construction to your hub design is non-negotiable.

Wide 5 platforms remain popular in classic car communities and specialty automotive segments where traditional lug patterns are preferred over modern designs. Hub seals in these assemblies must balance durability, thermal stability, and minimal drag to support both street reliability and weekend performance use. The air gap design of this DRP Performance seal makes it well-suited to applications where thermal management and reduced bearing friction matter—from vintage muscle car restorations to custom builds where bearing health directly impacts stopping power and handling consistency.
