        Great seal

        Felt tough out of the packaging and fit perfect. Following instructions known to all about leaky 4.0s, little bit of gasket seal around the rear and no more rear main leak!

      1 Top Rated Question

      I ordered this seal and one part of the seal doesn't have the side lips. It looks like I got two parts of the seal that go on the crankshaft and not the one that goes on the bearing cap. Is this how they are shipped?
