007 Drive Flange Locator O-Ring

The Winters 007 Drive Flange Locator O-Ring (part number 7490) is a precision rubber spacer engineered for Wide 5 rear axle assemblies. This component serves as a critical wear interface in differential and drivetrain assemblies, managing axial load distribution and maintaining proper spacing between rotating and stationary components in high-performance rear-end configurations.

Winters Performance is recognized for manufacturing OEM-quality drivetrain components, and this o-ring exemplifies that standard. The rubber composition resists degradation from heat cycling, gear oil exposure, and mechanical stress—common challenges in racing and high-output vehicle applications. The locator design prevents axial drift of the drive flange, which is essential for maintaining differential case concentricity and eliminating parasitic friction losses that compromise efficiency and longevity.

This o-ring is purpose-built for Wide 5 rear-end platforms, commonly found in circle-track racing, drag racing, and street performance vehicles requiring robust differential construction. Replacement at routine service intervals—or during differential rebuild—ensures consistent clamping force and eliminates the risk of locator creep that leads to bearing preload loss or gear mesh degradation. The lightweight design (0.02 lbs) makes it suitable for high-RPM applications where rotating mass matters.

Technicians and builders select Winters components for their dimensional accuracy and material consistency. The 007 Drive Flange Locator O-Ring is sold individually, allowing for targeted replacement without requiring a complete assembly kit when only the spacer requires service.
