ACL Bearings 4B8341-1.00 Connecting Rod Bearing Set Oversize - 1.00mm

The ACL Bearings 4B8341-1.00 is a high-performance connecting rod bearing set designed with 1.00mm (0.040") oversize dimensions for reground crankshafts. These Race Series bearings feature advanced tri-metal construction engineered to withstand the demanding conditions of high-performance and racing applications.

Key Features:

• Tri-metal construction with high-strength overlay plate for improved fatigue resistance
• Hardened steel backing provides enhanced support and retention in the connecting rod housing
• Increased crush ensures superior bearing retention and stability
• No flash plating on bearing backs maximizes heat transfer and grip in the housing
• Increased eccentricity compensates for bore distortion at high RPM
• Tight wall thickness tolerances maintain consistent oil clearances
• Precision machined to micron-level tolerances for reliable fitment
• Enlarged ID chamfers accommodate large fillet radius performance crankshafts

ACL Race Series bearings are manufactured in Tasmania, Australia, and deliver race-proven durability for street performance, drag racing, and road racing applications. The 1.00mm oversize specification is designed for use with crankshafts that have been ground 1.00mm undersize on the connecting rod journals.
