What does 'standard size' mean for these rod bearings?

Standard size means these bearings are designed to fit a crankshaft with its original factory specifications. If your crankshaft has been ground undersize due to wear or modification, you would need a different size bearing set.

What is tri-metal construction?

Tri-metal bearings have three layers: a steel backing for strength, a middle layer of alloy (often copper-lead-tin) for load carrying capacity, and a thin overlay of babbitt (a softer alloy) for conformability and embeddability. This combination is popular for performance engines.

Does this set include bearings for all connecting rods?

Yes, this is a complete set of connecting rod bearings for a V8 engine, meaning it includes enough bearings for all eight connecting rods.

Product Details

If you're building a performance Chevrolet V8, especially one with a 305, 350, or 400 small block, or an LS Gen III & IV engine, these ACL Race Series rod bearings are a solid choice. They're designed to handle the increased demands of a performance engine, offering a reliable foundation for your build.

These bearings are made with a tri-metal construction, which is a popular choice for performance applications because it offers a good balance of strength and conformability. This means they can handle higher loads and temperatures while still maintaining good oil film support. Being a standard size, they're intended to be used with a factory-spec crankshaft, ensuring a direct fit without needing any machining. ACL has a good reputation for making well-built engine components, and this set is no exception.

This set includes bearings for all the connecting rods in your V8 engine. Make sure to follow the manufacturer's installation instructions carefully, as proper bearing installation is critical for engine longevity.
