If you're rebuilding an engine or looking to get the most out of a performance build, these ACL high-performance main bearings are a solid choice. They're designed to handle the increased demands of modified engines, offering improved durability and oil control. These bearings are 0.025mm oversized, which is crucial if your crankshaft journals have been machined to match. Using the correct undersize or oversize bearing is essential for proper oil clearance and engine longevity.

ACL has been making engine bearings for a long time, and these are well-built for performance applications. They use a specialized overlay material that's designed to withstand higher loads and temperatures compared to standard bearings. This means they can help protect your engine's rotating assembly when you're pushing it harder, whether that's on the street or the track. When you're installing these, make sure to follow the manufacturer's recommended oil clearance specifications for your specific engine build.

This set of bearings is designed to fit a range of popular Acura and Honda engines, including B-series VTEC and K-series engines. Always double-check your engine code and crankshaft journal size to ensure you're getting the right fitment for your project.
