O-Ring - Reverse Shaft

The O-Ring - Reverse Shaft (MPN 67481) from WINTERS is a critical sealing component designed for high-performance differential assemblies and transmission systems. As a mechanic working with modified vehicles, you'll recognize this as an essential wear item for maintaining pressure integrity in reverse shaft applications. Whether you're rebuilding a performance differential after a track day or performing routine maintenance on a heavily-modified gearbox, this OEM-quality o-ring prevents fluid leakage and maintains optimal hydraulic pressure where it matters most.

Engineered to WINTERS specifications, this o-ring is manufactured from durable elastomer material formulated to withstand the thermal cycling and pressure spikes common in high-output powertrains. The compact dimensions (approximately 2 x 0.3 x 3.3 inches) allow precise fitment within tight differential housings, while the cross-sectional design creates a reliable metal-to-rubber seal. At just 0.02 lbs, weight is negligible, but the sealing performance is mission-critical—a failed reverse shaft o-ring leads to fluid loss, noise, and potential gear damage that can sideline your build indefinitely.

This replacement o-ring is ideal for anyone rebuilding a WINTERS differential, servicing a performance transmission, or addressing a known leak in a modified driveline. Keep one on hand during any differential tear-down—o-rings degrade over time and should always be replaced during reassembly, never reused. Compatibility is universal for WINTERS reverse shaft applications; verify part number 67481 against your specific differential documentation before ordering to ensure exact fit.
