What is Trimetal construction?

Trimetal bearings use a three-layer metal construction. This design helps manage oil flow and heat effectively, which is crucial for the longevity of your engine's crankshaft.

Do these bearings come with installation hardware?

This set includes the main bearings themselves. You will need to refer to your engine's service manual for specific installation procedures and any additional hardware or sealants required.

Are these bearings suitable for a high-performance build?

ACL Trimetal bearings are well-regarded for their durability and performance. They are a solid choice for both stock replacement and many performance engine builds needing reliable crankshaft support.
