Nothing fits better or performs better than genuine gm rear seal on LS engines. Do it once and not worry about a leak anymore.

The price is not about not cleaning the back cover and trying to get the seal in just right . I have the tools to do it, but mine seem to seep. I put this cover on, no more seeping. Every time from now on!
