What does the extra oil clearance mean for my engine?

The extra 0.025mm (0.001 inch) oil clearance allows for a slightly larger oil film between the bearing and the crankshaft journal. This can help reduce operating temperatures and ensure better lubrication, especially in high-performance applications that see higher RPMs and loads.

Are these bearings suitable for a stock engine rebuild?

These bearings are designed with extra oil clearance for high-performance applications. While they can be used in a stock rebuild, it's important to ensure your crankshaft journals are in excellent condition and that the rest of your engine build can benefit from this enhanced lubrication.

What is the difference between standard and undersize bearings?

Standard size bearings are meant to be used with a crankshaft that has not been machined or has been reconditioned to its original factory size. Undersize bearings are used when the crankshaft journals have been machined down to correct for wear or damage.

Product Details

When you're building a high-performance Ford engine, especially a Cosworth BDA or its variants like the BDB, BDC, or BDD, the details matter. These ACL 4 BD Series rod bearings are built for those engines, specifically for the 1099-1700cc range. They come standard size, which is what you'll want if you're not machining the crankshaft journals. What sets these apart is the extra 0.025mm (0.001 inch) of oil clearance built right in.

This added clearance means a slightly thinner bearing shell, which allows for a bit more oil to flow around the crankshaft journal. For a performance engine that's going to be pushed hard, this improved oil flow is crucial for keeping temperatures down and ensuring proper lubrication, especially under high RPMs. ACL has been making engine bearings for a long time, and these are a solid option for anyone serious about their build.

When installing these bearings, make sure to follow the manufacturer's recommended torque specifications for the connecting rod bolts. It's also a good idea to check the crankshaft journals for any imperfections that could damage the new bearings.
