ACL Bearings 8B818P-40 Connecting Rod Bearing Set Oversize Ford - 0.40mm 370 429 460

The ACL Bearings 8B818P-40 is a premium trimetal connecting rod bearing set engineered specifically for Ford Big Block V8 engines including 370, 429, and 460 cubic inch applications from 1968-1998. This 0.40mm oversize bearing set is designed for crankshafts that have been ground undersize during rebuilding or performance upgrades.

Trimetal Construction for Enhanced Durability:

These bearings feature ACL's proven trimetal design with a copper-lead-tin alloy bonded to a hardened steel backing. This construction provides superior load-carrying capacity, excellent fatigue resistance, and the dependability required by larger displacement V8 engines. The hardened steel backs improve bearing retention in the housing and enhance support of the bearing lining under demanding conditions.

Key Features:

• Trimetal construction (copper-lead-tin alloy) for extra durability and load capacity
• Hardened steel backing for improved retention and lining support
• 0.40mm oversize specification for reground crankshafts
• Enlarged ID chamfers to accommodate performance crankshaft fillet radius
• Precision engineered to OEM specifications with minimal tolerance
• ISO certified manufacturing process ensures consistent quality

ACL bearings are ideal replacement components for street rods, muscle cars, performance rebuilds, and recreational applications. The trimetal metallurgy offers excellent performance characteristics for engines operating in medium to high RPM ranges, providing the durability needed without the extreme race-only specifications of professional competition bearings.
