Review on 🚗 Fel Pro Rear Main Seal for Chevrolet 40640 by Andrew Britton

Used on a 1999 Silverado 5.3L Gen 3rd LS. Fit and functionality were top notch. Now is not the time to save work or hack. If you don't like pulling on gears, I highly recommend using a cap alignment tool, otherwise you will most likely cause premature crank seal leakage at some point or all at once. through contradiction! Also remember that the seal must be mounted "this side out", towards trance you will find a small text on the edge of the seal.
