What does '0.25mm undersize' mean for these main bearings?

This means the bearings are manufactured to be slightly smaller than the original factory size. They are designed to be used when the engine's crankshaft has been machined down by 0.25mm to correct for wear or damage. This ensures the correct clearance between the crankshaft and the main bearings.

What type of engine is this bearing set designed for?

These bearings are made from a bi-metal aluminum composite that is ideal for engines experiencing low to medium loads. This makes them a good choice for many standard street applications rather than extreme racing conditions.

Are these bearings environmentally safe?

Yes, these bearings feature a lead-free composite material, making them an environmentally safe option.
