Hub Seal Viton Modified Wide 5 & 5x5

The Winters Hub Seal Viton Modified Wide 5 & 5x5 is a precision wheel hub seal engineered for vehicles running Wide 5 or 5x5 bolt patterns—a configuration common in high-performance, off-road, and classic automotive platforms. This inner lip seal features a 3.75-inch outer diameter with a 3-inch inner diameter and 0.375-inch thickness, designed to mount on the front wheel hub and contain bearing grease while blocking contaminants and moisture. Built with Viton elastomer construction, this seal delivers superior chemical and temperature resistance compared to standard rubber seals, making it essential for vehicles exposed to harsh environments, extended storage, or extreme operating conditions.

The 0.375-inch thickness and modified design provide robust sealing integrity during highway driving, off-road articulation, and desert racing—scenarios where inferior seals fail prematurely due to heat cycling, abrasive dust, and water intrusion. Viton material excels where standard rubber compounds degrade, maintaining elasticity across temperature swings and resisting petroleum-based brake fluids and coolant splash-back. The modified lip geometry ensures consistent contact pressure against the hub surface without binding during wheel rotation or suspension flex. At just 0.1 lbs, installation is straightforward with standard seal-pulling tools and bearing repack procedures.

This seal is critical for owners rebuilding Wide 5 or 5x5 wheel hubs during maintenance intervals, conducting brake service, or restoring classic performance vehicles that rely on precise bearing clearances. The correct seal prevents bearing contamination that would compromise wheel integrity and safety—a non-negotiable component in any professional hub assembly. Supplied as a single unit, this seal pairs with standard cartridge or tapered roller bearings commonly found in vintage muscle cars, hot rods, and modern off-road platforms using this bolt pattern configuration.
