What does '0.025mm oversized' mean for these main bearings?

This means the bearings are slightly larger than the standard factory size. They are intended for use when the crankshaft journals have been machined down by 0.025mm to create a fresh, smooth surface for the new bearings to run on.

Are these bearings suitable for a stock engine rebuild?

These are considered high-performance bearings and are specifically sized at 0.025mm oversized. They are best suited for performance engine builds where the crankshaft has been machined to accommodate this size, rather than a standard stock rebuild.

Product Details

ACL has been making engine bearings for decades, and this high-performance main bearing set for your 2000-2009 Honda S2000 is one of their staples. These bearings are specifically sized at 0.025mm oversized, meaning they're intended for engines where the crankshaft journals have been machined down to match this size during a rebuild. They're built to handle the demands of performance applications, providing a solid foundation for your F20C or F22C engine.

When you're rebuilding or modifying your S2000's engine, the main bearings are critical for supporting the crankshaft and ensuring smooth operation. ACL uses well-built materials and manufacturing processes to create bearings that offer improved durability and performance compared to stock. The 0.025mm undersize is a common machining size for performance builds, allowing for a fresh surface on the crankshaft journals and a precise fit with these ACL bearings.
