Positioned right at the front of the differential where the propshaft flange meets the pinion shaft, this high-grade seal is a non-negotiable replacement whenever you pull your diff apart or notice oil weeping around the nose of the axle casing.
Over time, heat, road grime, and constant shaft rotation take a toll on rubber seals, causing them to harden and crack. This Blackline replacement uses premium elastomeric compounds designed to handle high oil temperatures and severe motorsport use without breaking a sweat, ensuring your expensive gear oil stays inside the casing where it belongs.
