Product Details

The ACL Bearings 5M1039P-20 is a high-performance main bearing set designed for precision engine rebuilds requiring 0.020" undersize bearings. Engineered with ACL's proven tri-metal construction, this bearing set delivers exceptional durability and performance for demanding applications.

Key Features:

I reciently ordered some spark plug wires from Autoplicity and I must say it was a great experience. The shipping was fast and they had the best price I could find. I will def order parts for my truck from them again.
