The ACL Bearings 5M8361A-STD is a standard size main bearing set engineered for high-performance and racing applications. These main bearings feature ACL's proprietary Aluglide bearing material, a tri-metal construction that combines an aluminum-tin alloy overlay on a steel backing, providing exceptional wear resistance and fatigue strength under extreme loads and temperatures.

Key Features:

• Aluglide tri-metal bearing material for superior durability and load capacity
• Standard size (STD) for engines without prior machining or wear
• Aluminum-tin overlay provides excellent embeddability and conformability
• High crush design ensures proper retention in the housing bore
• Engineered for both street performance and racing applications
• Precision manufactured to OEM specifications for proper oil clearances

ACL Race Series bearings are designed to meet the demanding requirements of high-performance engines, offering the perfect balance of strength, durability, and friction reduction. The Aluglide material excels in applications where extreme loads and elevated temperatures are present, making these bearings ideal for turbocharged, supercharged, and high-compression naturally aspirated engines.
