ACL Bearings 5M7292H-010 Race Series Main Bearing Set .010 Oversized Chevy Gen V LT1/LT4/L86

The ACL Bearings 5M7292H-010 is a high-performance Race Series main bearing set engineered specifically for Chevrolet Gen V LT1, LT4, and L86 V8 engines. This set features .010 inch (0.254mm) oversized bearings designed for use with reground crankshafts or worn bearing bores requiring additional clearance.

Advanced Tri-Metal Construction:

These Race Series bearings utilize tri-metal construction combining a hardened steel backing, copper-lead alloy intermediate layer, and high-strength overlay plate with reduced thickness for superior fatigue resistance. The steel backing maintains bearing crush under extreme loads and temperatures, while the overlay provides excellent seizure resistance and conformability.

Key Features:

• Tri-metal construction designed for high RPM and high-load racing conditions
• Hardened steel backing for improved bearing retention and lining support
• Reduced overlay thickness for enhanced fatigue strength and durability
• Increased crush for superior bearing retention in the housing
• Increased eccentricity to compensate for bore distortion at high RPM
• 3/4 groove design optimizes oil supply to connecting rods while maximizing load-carrying surface area
• Elimination of flash plating on bearing backs improves heat transfer
• Large chamfers accommodate larger crankshaft fillets
• Precision manufactured to exact tolerances for consistent clearances
