ACL 1967-2007 Chevy V8 305/350/400 .01mm Oversized Trimetal Rod Bearing Set

Already rebuilt the bottom end of your small-block Chevy? This trimetal rod bearing set from ACL is the next piece of the puzzle. These bearings are designed to handle the demands of performance V8 engines, ensuring proper lubrication and reduced friction between the connecting rod and crankshaft. They are specifically sized at .01mm undersize, which is crucial for engines that have had their crankshaft journals ground down during a rebuild.

ACL uses a trimetal construction, which is a well-built layering of materials that offers excellent strength and conformability. This means the bearings can adapt to the crankshaft surface while providing a strong, durable interface. The .01mm undersize specification is important because it accounts for the material removed from the crankshaft journals when they are reconditioned to a smoother finish. Using the correct undersize bearing ensures the proper oil clearance is maintained, which is critical for engine longevity and performance.

When you're putting together a performance engine or rebuilding a classic, getting the bearing clearances right is key. This ACL set is a solid option for 305, 350, and 400 small-block Chevy engines, offering a reliable and durable solution for your build.
