What does '0.25mm Oversize' mean for these rod bearings?

This means the bearings are slightly larger than standard size. They are designed to be used when the crankshaft journals have been machined down by 0.25mm to ensure a proper fit and oil clearance.

Do these bearings come with new bolts or hardware?

This product includes a set of 8 rod bearings. Installation hardware, such as connecting rod bolts, is not included and should be sourced separately if needed.

What is the typical lifespan of these ACL rod bearings?

ACL bearings are well-built for performance applications. Lifespan depends heavily on proper installation, oil quality, maintenance intervals, and engine operating conditions.
