Product Description

The ACL 7M8103H-.25 Race Series Main Bearing Set is engineered for the Toyota and Lexus 2JZ-GTE and 2JZ-GE engines found in various models from 1991 to 2005. These bearings are designed to provide enhanced durability and performance under high-RPM and track applications.

Constructed with ACL's Trimetal technology, combining copper, tin, and lead, these bearings offer superior durability and resistance to wear under extreme operating conditions. The hardened steel backs enhance support and retention, while the increased crush design ensures improved bearing retention.

The elimination of flash plating on the back of the bearings improves heat transfer, and the 3/4 groove design ensures optimal oil flow to critical engine components, maintaining consistent performance and reliability. With a .25mm oversize, these bearings are suitable for engines requiring additional clearance.
