Product Details

When you're rebuilding or refreshing a big block Chevrolet V8, especially one of the 396, 402, 427, or 454 cubic inch variants, the connecting rod bearings are a critical component. ACL's Race Series bearings are built with a high-performance overlay that's designed to handle the increased loads and temperatures found in performance applications. They feature a tri-metal construction with a steel-backed overlay for strength and a specialized bearing material that resists fatigue under stress.

These bearings are a popular choice for engine builders looking for a solid upgrade over stock. The 'H' in the part number indicates a hardened steel back, which adds extra rigidity to the bearing assembly. They are designed to fit precisely within the connecting rod and crankshaft journals, ensuring proper oil clearance for lubrication and cooling. If you're building an engine for racing or heavy-duty use, these bearings offer a well-built option to support your build.

This set includes all the bearings needed for one bank of cylinders. Remember to check your crankshaft and connecting rod journal dimensions to ensure proper fitment and to consult the manufacturer's installation instructions for specific clearance and assembly details.
