What is the CT-1 coating on these bearings?

The CT-1 coating is an advanced surface treatment ACL uses to help reduce friction between the bearing and the crankshaft. It also helps with oil retention, which is important for keeping the bearings properly lubricated and cool.

Do these bearings come with installation instructions?

While specific installation instructions are not included with the product, it is critical to follow the manufacturer's recommended procedures for engine bearing installation. This includes checking oil clearances and ensuring proper lubrication.

What does 'Standard Size' mean for engine bearings?

Standard size bearings are meant to be used with a crankshaft that has not been machined or ground undersize. If your crankshaft journals are within the factory specifications, standard size bearings will provide the correct oil clearance.

Product Details

Doing an engine rebuild on your Acura Integra, RSX, TSX, or Honda Accord, CR-V, Civic, or Element? These ACL High Performance main bearings are a solid choice for getting your engine back in shape. They're built to handle the demands of performance builds and everyday driving alike, ensuring your crankshaft spins smoothly and reliably.

ACL uses a special CT-1 coating on these bearings. This advanced coating helps reduce friction and improve oil retention, which is crucial for keeping your engine cool and preventing wear, especially during break-in or under heavy load. They're made to standard size, so they'll fit perfectly with your factory crankshaft journals if they're still within spec. If you're building a performance engine or just want a well-built replacement, these bearings offer a good balance of durability and performance.

When you're installing these bearings, make sure to follow the manufacturer's instructions carefully. Proper oil clearance is key to their performance and longevity. If you've already had your crankshaft journals measured and they're within the standard size range, these ACL bearings are ready to go in.
