Bearing Spacer Inner Wide 5 2-7/8in Hub

The Bearing Spacer Inner Wide 5 2-7/8in Hub from Winters is an essential precision component for high-performance rear axle assemblies and custom vehicle builds. This steel spacer is engineered specifically for Wide-5 bolt pattern hubs, a configuration common in drag racing, circle track competition, and serious street rod modifications. Whether you're building a custom suspension setup or maintaining an existing performance axle system, this bearing spacer ensures proper wheel bearing preload and alignment, which directly impacts handling, tire wear, and safety during acceleration and cornering.

Constructed from high-strength steel, the Bearing Spacer Inner Wide 5 2-7/8in Hub is precision-manufactured to exacting tolerances required for reliable bearing fit and spindle clearance. The 2-7/8-inch dimension is critical—it spaces the inner bearing seat to maintain the correct axle geometry and bearing preload without binding or play. At 0.2 lbs, this lightweight component integrates seamlessly into Wide-5 hub assemblies without adding unnecessary unsprung weight. Proper bearing spacer selection prevents cone creep, extends bearing life, and maintains accurate brake rotor runout, all factors that directly influence vehicle stability and braking performance on the street or strip.

Mechanics and fabricators building or rebuilding Winters Wide-5 hub rear ends will find this spacer indispensable for proper axle assembly. It's ideal for vintage hot rods, modern restorations, and dedicated race vehicles where precision axle geometry is non-negotiable. Always verify hub dimensions and spindle specifications before installation to ensure correct fit, and pair with matching bearing cones, cups, and seals for optimal results. This is a consumable wear item for serious builders—stock it alongside bearing kits and axle components for complete, reliable axle assemblies.
