5M1039P ACL TriMetal Main Bearings – Ford 429 460 – Std size

Description

Orbit Trimetal rod and main bearings were developed for engine builders and enthusiasts who prefer copper-lead-tin bearings (trimetal) over aluminum-tin metallurgy (bimetal). And especially for those who build the larger V-8s (400, 427, 350, 327, 302, etc.). Trimetal bearings offer the extra durability, load-carrying capacities and dependability required by larger and more powerful engines. They provide the desirable performance characteristics but not quite the high performance capacity of our Race Series bearings required by professional racers. Orbit Trimetal Bearings are ideal replacement bearings for street rods, muscle cars and similar recreational interests.
