ACL Bearings 2B1886-1.25 Connecting Rod Bearing Set Oversize - 1.25mm

The ACL Bearings 2B1886-1.25 connecting rod bearing set is engineered for high-performance engine builds requiring 1.25mm (approximately .050") oversize bearings. ACL Race Series bearings are recognized throughout the motorsports world for their exceptional durability and precision engineering, making them the choice of professional engine builders and racers.

Key Features:

• 1.25mm oversize dimension accommodates crankshafts with machined journals during engine rebuilds
• Hardened steel backing improves bearing lining support and assists with retention in the housing
• Advanced metallurgy with optimized material composition for enhanced fatigue resistance
• Elimination of flash plating on the back improves heat transfer and maximizes grip between bearing and housing
• Tight, consistent wall tolerances help maintain precise oil clearances during assembly
• Increased eccentricity compensates for bore distortion at high RPM and assists in hydrodynamic oil film formation
• Enlarged inner diameter chamfers on bearing edges accommodate large fillet radius on performance crankshafts

ACL bearings combine advanced design, superior metallurgy, and precision engineering to deliver exceptional performance in street, strip, and racing applications. These connecting rod bearings are built to withstand elevated loads, high RPM conditions, and extreme operating temperatures where standard bearings cannot perform.
