Product Description

The **ACL 4M8468H-STD Race Series Main Bearings** are high-performance engine bearings designed for Toyota's 2GR-FE 3.5L V6 DOHC engine family - a popular powerplant found in a wide range of Toyota and Lexus models from approximately **2005 through 2024** as well as in the Lotus Evora and Exige when equipped with the same engine architecture. These bearings are engineered with ACL's Race Series technology, featuring a tri-metal F780 alloy and hardened steel backing that provides superior durability and resistance to fatigue under elevated RPM and demanding conditions compared with basic OE bearings.

Built to maintain optimal lubrication and clearances in performance applications, the 4M8468H-STD set includes main bearings with 3/4 grooved designs to enhance oil distribution and bearing load support. Tight wall tolerances and enhanced bearing geometry help ensure consistent film formation and heat transfer critical to longevity and reliability under stress. Ideal for engine rebuilds, performance upgrades, or motorsport use, these Race Series main bearings offer a robust upgrade path for Toyota 2GR-FE powered vehicles and Lotus performance models.
