Product Details

ACL has been making engine bearings for decades, and this crankshaft main bearing set for your Chevrolet V8 is one of their staples. These bearings are crucial for keeping your crankshaft spinning smoothly within the engine block. They sit between the crankshaft journals and the engine block, reducing friction and wear on these critical components. This set is designed for a range of Chevrolet V8 engines, including the popular 267, 305, 327, and 350 cubic inch displacements, covering a wide span of model years from 1967 through 1998.

When you're rebuilding an engine or addressing bottom-end noise, a fresh set of main bearings is essential. ACL uses well-built materials and manufacturing processes to ensure these bearings can handle the pressures and temperatures inside your engine. They are built to meet or exceed OEM specifications, meaning they'll fit right and perform reliably. Proper installation is key; ensure your crankshaft journals are clean and within spec, and always follow the manufacturer's recommended torque sequence and values when installing the main caps.

This set includes the main bearings needed for your engine. If you're doing a full engine overhaul, consider pairing these with a matching set of connecting rod bearings and checking your oil pump for proper flow and pressure.
