Product Description

The **ACL 5M7292H-STD Race Series Main Bearing Set** is a premium performance crankshaft bearing kit engineered specifically for **GM's Gen V 6.2 L small-block V8 engines** - notably the LT1, LT4, and L86 variants found across Chevrolet *Corvette*, *Camaro*, and 6.2 L-equipped *Silverado*, *Tahoe*, *Suburban*, *Yukon*, and more from **2014 through 2024**. These bearings are built to withstand higher RPMs and loads than standard replacement bearings, making them ideal for both high-performance street engines and motorsport applications.

Constructed with advanced tri-metal F780 alloy and hardened steel backing, the 5M7292H-STD bearings combine strength with precise oil film characteristics that support durability and performance. The 3/4-grooved main bearing design enhances lubrication flow and hydrodynamic film formation under load, maintaining consistent clearances and reliable crank support. An extra thrust/plain shell is included so builders can configure either 180° or 360° thrust arrangements depending on engine requirements - a flexibility advantage over OEM sets. These features make ACL Race Series bearings a strong choice for engine rebuilds, high-RPM use, and performance-oriented builds.
