What is the purpose of the performance coating on these bearings?

The performance coating on these King Engine Bearings is designed to reduce friction and wear. This is particularly beneficial during engine break-in and under high-stress operating conditions, helping to protect the bearing surface.

Why are these bearings 0.25mm undersize?

These bearings are 0.25mm undersize to accommodate crankshaft journals that have been machined down to that specific size. This ensures the correct oil clearance is achieved when using a reconditioned crankshaft.

What is the importance of proper oil clearance with rod bearings?

Proper oil clearance is essential for engine longevity. It allows a thin film of oil to form between the bearing and the crankshaft journal, reducing friction and heat. Too little clearance can lead to rapid wear, while too much can cause knocking and premature failure.

About this part

Product Details

If you're rebuilding the bottom end of your Acura B17A1, B18A1, or B18B1 engine, getting the right rod bearings is crucial for long-term health and performance. These performance coated rod bearings from King Engine Bearings are designed to handle the demands of a performance build, offering improved durability and reduced friction.

King uses a unique overlay coating on these bearings that helps to reduce friction and wear, especially during the critical break-in period and under high-load conditions. The bearings are manufactured to precise specifications, ensuring they fit right and maintain proper oil clearance. This set is specifically sized at 0.25mm undersize, which is important if your crankshaft journals have been reconditioned to this size.

When installing these bearings, always ensure your crankshaft journals are clean and within the specified size tolerance. Proper oil clearance is key to the longevity of your engine build.
