ACL 4B1946A-1.00 Oversized Rod Bearing Set

The ACL 4B1946A-1.00 is a specially designed oversized rod bearing set that caters to the needs of high-performance engines. Crafted with a unique blend of design and metallurgy, these bearings are engineered to withstand the rigors of higher RPM conditions, making them an ideal choice for enthusiasts looking to enhance their engine's performance.

Features

High strength overlay plate with a reduced thickness that improves fatigue properties.
Hardened steel backs provide better support for the bearing lining and enhance retention within the housing.
Increased crush for better bearing retention during operation.
Elimination of flash plating on the back of the bearings boosts heat transfer efficiency and maximizes grip within the housing.
Increased eccentricity helps counteract bore distortion at high RPM and aids in forming hydrodynamic oil films.
3/4 grooved main bearings optimize load-carrying surface area and ensure proper oil flow to the conrod bearings.
Tight, consistent wall tolerances help maintain uniform clearances.
Enlarged ID chamfers on bearing edges accommodate larger fillet radii found on performance crankshafts.
