Works on Dana 30, Dana 25 and 27 axles. Elastomer beading applied to the gasket face, which provides a dry and leak-free seal, even when exposed to high horsepower, differential and axle flex or wide temperature extremes. Premium grade metal base material with rubber coating. Uses a full perimeter beading all the way around and has a steel base to provide stability. No Sealant Required! Don't worry about splitting during the installation process. It has an amazing torque retention cover so that there is no sticking to the housing. .
