Good product for the price.
Installed on my 1989 f250 in a few minutes, doesn't take a genius to figure out. It's the only thing on my truck that isn't leaking. Works great.
Most Liked Negative Review
dont waste your time or money
Listed as replacement on 2004 f-150 but leaked right away the next time I drove. The more expensive seal does not leak. Poor design. If you look at the more expensive seal you can see the difference.
