LubeLocker Differential Cover Gaskets
LubeLocker differential gaskets make paper gaskets and RTV a thing of the past by manufacturing high-quality, aluminum core gaskets with an outer silicone coating. The real secret to LubeLocker's success, however, is the elastomer beading applied to the gasket face. This beading provides a dry, leak-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--it doesn't matter, LubeLocker differential gaskets will keep your lube where it belongs.
Brand new, just opened to realize I bought wrong one and too late to return.
Front 10-bolt 8.5 is different than rear.
