What is the advantage of tri-metal construction for engine bearings?

Tri-metal bearings use three layers of material to provide a strong yet adaptable surface. This construction helps reduce friction and wear, especially under the high loads and temperatures found in performance engines.

Do these bearings require any crankshaft machining?

These are standard size bearings, meaning they are designed to fit a crankshaft that is still within factory specifications. If your crankshaft has been previously machined or is worn beyond standard size, you may need to consult with a machine shop.

What other engine components are typically replaced during a rod bearing job?

When replacing rod bearings, it's common practice to also inspect and potentially replace piston rings, main bearings, and engine seals. It's also a good time to check connecting rod bolts for stretch and replace them if necessary.

Product Details

ACL has been making engine bearings for decades, and this standard size high-performance rod bearing set for your Acura Integra is one of their staples. These bearings are crucial for keeping your engine running smoothly by reducing friction between the crankshaft and connecting rods. If you're rebuilding an engine or looking to improve its reliability, especially if you're pushing the limits a bit, a well-built set of bearings like these is a smart move.

This set is built to handle the demands of performance applications. ACL uses a tri-metal construction, which is a popular choice for high-stress engine builds because it offers a good balance of strength and conformability. This means the bearings can adapt to the crankshaft surface while still providing solid support. They are manufactured to standard size, so they're designed to fit directly onto a factory-spec crankshaft without needing any machining, making your rebuild process more straightforward.

When you're putting an engine back together, especially one that's seen some miles or is being built for more power, using reliable internal components is key. These ACL bearings are a solid option for anyone working on a B17A1, B18A1, or B18B1 engine found in various Acuras and Hondas.
