Semi Truck Engine Valve Stem Seals

This product is better than the regular stock. I would definitely buy it again if I ever even have too. The installation well you know if you have built an engine before. I do wish though that they can put one extra o-ring, and valve stem in the package, for the same price.

This product is way better than the stock is. I was rebuilding my 1992 5.7L engine, the stock was a little pricey but this was better it came with everything I needed. Made out of different stuff then stock, and looks good too.
