What does '.40mm oversized' mean for these bearings?

This means the bearings are designed to fit a crankshaft that has been machined down by 0.40mm. This is a common practice during engine rebuilds to ensure a fresh, perfectly sized surface for the new bearings.

What is trimetal construction?

Trimetal bearings have three layers of material. This construction is chosen for its ability to handle high loads and temperatures, offering a good balance of strength, wear resistance, and conformability to the crankshaft.

Do these bearings come with installation instructions?

While these bearings are designed for a specific fitment, it is always recommended to refer to the manufacturer's installation instructions or a qualified mechanic for proper installation procedures and torque specifications.

Product Details

200,000 psi tensile strength puts these ACL bearings well above stock hardware. When you're rebuilding a classic Chevy V8 like a 265, 283, 302, or 327, getting the engine bearings right is crucial for longevity and performance. These are trimetal rod bearings, meaning they have three layers of material designed to handle the high loads and temperatures inside your engine. The .40mm oversize means they're intended for crankshafts that have been machined down by 0.40mm, which is common in engine rebuilds to ensure a fresh, perfectly sized surface for the bearings to run on.

ACL has been making engine bearings for a long time, and their trimetal construction is a popular choice for performance builds and restorations alike. This design offers a good balance of strength, wear resistance, and the ability to conform slightly to the crankshaft for optimal oil film. They're well-built to handle the demands of these iconic V8s, whether you're going for a stock restoration or a mild performance upgrade. Proper installation is key here; make sure your crankshaft journals are clean and within the specified tolerance for these .40mm undersize bearings.

This set is designed to fit a range of Chevy V8 engines from 1955 through 1967, including popular models like the Bel Air, Impala, and Corvette. If you're in the middle of a rebuild and need reliable rod bearings that are sized for a machined crankshaft, this ACL set is a solid option.
