Product Description

The **ACL 5M8632H-STD Race Series Main Bearing Set** is a premium performance component engineered for **Toyota and Lexus V8 engines** - specifically the 1UR-FE, 2UR-FSE, and 3UR-FE family used in full-size trucks, SUVs, and performance models from **2007 through 2023**. These bearings are designed to handle higher-than-stock RPM and load conditions, making them ideal for engine rebuilds, performance upgrades, and tuning applications where improved lubrication and durability are demanded. ACL's Race Series bearings feature a robust tri-metal F780 alloy construction with hardened steel backing to deliver strength and resistance under sustained high stress.

With a 3/4 grooved design that optimizes oil flow to critical bearing surfaces and tight, consistent wall tolerances that promote reliable oil film formation, the 5M8632H-STD main bearings help maintain dependable crankshaft support in demanding conditions. Enlarged chamfers and increased eccentricity further enhance performance, while the elimination of flash plating improves heat transfer and bearing grip within the housing. Ideal for Toyota Tundra, Sequoia, Land Cruiser, Lexus IS F, GS, GX, RC F, LC500, and LS series models equipped with compatible V8 engines, this main bearing set offers a robust upgrade over standard OEM bearings.
