O-Ring Posi-Lock

The O-Ring Posi-Lock by Winters is a precision locking ring designed for high-performance differential assemblies and gear carrier applications. This component is essential for those building or maintaining a serious performance drivetrain, ensuring secure gear carrier retention and preventing unwanted movement under extreme load.

The O-Ring Posi-Lock functions as a positive locking ring that works in conjunction with standard O-ring seals to maintain axial retention. Its compact 0.25-inch width is engineered to fit precision carrier bores, while its design philosophy reduces the risk of carrier ring migration that could lead to seal failure or differential noise under load conditions.

Anyone performing a differential rebuild or upgrading to higher-performance gears should include the O-Ring Posi-Lock in their parts kit. This component is particularly valuable for high-horsepower vehicles where shock loads can compromise differential function.
