What does '.40mm oversized' mean for these bearings?

This means the bearings are manufactured to be slightly larger in diameter than standard. They are intended for use when the crankshaft journals have been machined undersize (ground down) during an engine rebuild to remove imperfections or wear.

What is trimetal construction?

Trimetal bearings typically consist of three layers: a steel backing for strength, a copper-lead alloy for embeddability and strength, and a thin overlay of babbitt (a soft alloy) for low friction and conformability against the crankshaft.

Do these bearings come with a warranty?

ACL typically offers a limited warranty on their engine bearings. Please refer to the manufacturer's documentation or contact ACL directly for specific warranty details and coverage.
