As a lead-free OE replacement, they provide a reliable, environmentally friendly solution for both stock rebuilds and light performance applications.
Designed with a .002″ oversize diameter, these bearings are perfect for blocks that require housing repair via line honing. Suited for engines with a thrust bearing in the #5 position, they deliver a precise fit and long-lasting performance.
