Hi quality, steel core gasket with a rubber coating. The
real secret to LubeLocker's success however is the
elastomer beading applied to the gasket face. This beading
provides a dry, leaf-free seal, even when exposed to high
horsepower, differential and axle flex, or wide temperature
extremes. Drag racing, circle track, rock climbing, off-road,
desert racing, doesn't matter! LubeLocker differential
gaskets will keep your lube where it belongs.
