Seal Retaining Ring - Wide 5 / Baby Grand

The Seal Retaining Ring - Wide 5 / Baby Grand by Winters is a critical drivetrain component engineered for high-performance automotive and heavy-duty applications requiring reliable differential or transmission assembly. This compact yet robust retaining ring serves as the primary seal-locking mechanism in Winters differentials and gear systems, preventing fluid leakage and maintaining internal component alignment under extreme load and sustained RPM cycles. Available for Wide 5 and Baby Grand configurations, this part is essential for technicians, restoration specialists, and performance vehicle builders who demand OEM-equivalent or superior reliability in their drivetrain systems.

Manufactured to exacting tolerances, the Seal Retaining Ring features a precision-engineered ring design that secures seal assemblies while accommodating the rotational and thermal expansion demands of modern differentials. The Wide 5 / Baby Grand designation ensures compatibility with Winters' most popular differential housings, commonly found in drag racing, off-road, and high-performance street applications. Weighing just 0.04 lbs and measuring 4.95 x 0.1 x 12.5 inches, the compact profile minimizes installation complexity while its hardened steel construction resists deformation, corrosion, and fatigue cracking—critical factors in maintaining seal integrity during sustained acceleration and aggressive driving conditions.

Performance builders, racing teams, and differential specialists rely on this Winters OEM component (MPN 8328) to ensure long-term drivetrain durability and leak-free operation. Whether you're rebuilding a street rod differential, servicing a competition-grade rear end, or restoring a vintage performance vehicle, proper seal retention directly impacts fluid containment and component longevity. Installation requires removal of the differential cover and careful alignment during reassembly; consult your Winters differential service manual or a qualified technician if you lack hands-on experience with drivetrain service. Keep this essential retaining ring in your rebuild kit to guarantee a professional-grade restoration.
