What is the main benefit of the lead-free composite material?

The lead-free composite material is environmentally safe. It's also ideal for engines that operate under low to medium load conditions, offering reliable performance.

What does the '+0.25mm' size indicate?

The '+0.25mm' indicates that this main bearing set is 0.25 millimeters larger than the standard size. This is typically used when the crankshaft journals have been machined to a larger diameter during an engine rebuild.
