What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are intended for crankshaft journals that have been machined down by 0.25mm during an engine rebuild. This is a common practice to ensure a proper fit and oil clearance on a crankshaft that has been worn or resurfaced.

What is the benefit of a silver-based bearing overlay?

A silver-based overlay is a well-built material that offers excellent strength and durability. It's chosen for its ability to withstand high loads and temperatures, providing consistent oil film support and reducing friction and wear on critical engine components like the crankshaft.

Do these bearings come with installation hardware?

This product is a set of connecting rod bearings only. Installation hardware, such as new rod bolts or nuts, is typically sold separately and should be sourced according to your engine's service manual specifications.
