Hub Wide 5 Rear 2-7/8 Kit

The Winters Hub Wide 5 Rear 2-7/8 Kit (Part Number 3750) is a complete rear wheel hub assembly designed for high-performance and custom automotive applications requiring a Wide 5 bolt pattern. This precision-engineered hub combines a 2-7/8-inch width with a 24-spline drive flange, delivering the rigidity and accuracy demanded in drag racing, circle track, and serious street performance builds where wheel fitment and load capacity are non-negotiable.

Constructed from aluminum and finished in polished form, this hub assembly arrives ready to install with all necessary components included: sealed bearings, hardware, and wheel studs. The 24-spline drive flange provides a secure interface with drive axles commonly found in dedicated racing platforms and custom hot rod builds. The Wide 5 configuration (five bolt holes on a specific diameter) is a standard in circle track and drag racing circles, where interchangeability with existing wheels and proven durability over decades make it a benchmark choice. At 10.36 lbs, the hub contributes minimal unsprung weight while maintaining the structural integrity required to handle cornering loads and launch forces in competitive environments.

This rear hub assembly is engineered for builders and racers who demand pre-assembled, turnkey solutions. The inclusion of bearings, studs, and hardware eliminates sourcing multiple components and ensures proper bearing preload and spec compliance. Racers upgrading vintage platforms, circle track competitors standardizing on proven components, and custom builders working with Wide 5 wheel packages will find this kit accelerates build timelines while maintaining the precision fitment that translates to predictable handling and wheel retention under stress.
