ACL Bearings 4B2260HX-STD Race Series Connecting Rod Bearing Set with Extra Clearance

ACL Race Series 4B2260HX-STD is a high-performance connecting rod bearing set engineered to provide an extra 0.001 inch of oil clearance for demanding racing and performance applications. These HX-STD bearings feature walls that are 0.0005 inch thinner per half compared to standard H-STD bearings, allowing for optimized oil flow and clearance on standard-sized crankshafts.

Key Features:

• High strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backs on all rod bearings to improve bearing lining support and retention
• Increased crush for improved bearing retention and elimination of flash plating to maximize heat transfer
• Increased eccentricity to compensate for bore distortion at high RPM
• Manufactured to exacting tolerances with micron-level machining for consistent wall thickness and crush
• Enlarged ID chamfers on bearing edges to accommodate large fillet radius on performance crankshafts

ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world, delivering the tri-metal construction and precision engineering required for championship-winning race engines. The unique blend of characteristics provides high strength and excellent seizure resistance under the most demanding conditions.
