Comments about Felpro Rear Main Seal Set:

This rear main seal is a direct replacement for the factory seals which become brittle and leak over time. They are a perfect fit but require removal of either the engine or the transmission as well as the oil pan for proper installation. I recommend going ahead and purchasing the front main seal, oil pan gasket and valve cover gasket because chances are if your rear main seal has begun to leak then the other seals and gaskets most likely aren't far behind.
