ACL Bearings 8B927PO/S2-30 Performance Connecting Rod Bearing Set Undersize - 030

The ACL Bearings 8B927PO/S2-30 is a high-performance connecting rod bearing set designed for precision engine builds requiring .030 inch undersize bearings. This bearing set features ACL's advanced tri-metal construction with a steel backing, copper-lead intermediate layer, and a tin-aluminum overlay for superior strength and wear resistance.

Key Features:

• Tri-metal performance construction for enhanced durability and load capacity
• .030 inch undersize for reground crankshafts
• Steel back construction provides superior bearing retention in the housing
• High fatigue strength overlay material for extreme conditions
• Precision manufacturing ensures consistent oil clearances
• Compatible with a wide range of performance and racing applications

ACL's PO/S2 series bearings are engineered for demanding performance applications where standard bearings may not provide adequate protection. The undersize dimension allows for proper clearances when using a crankshaft that has been ground .030 inch undersize, making this an ideal choice for engine rebuilds and performance upgrades. Each bearing is manufactured to exacting tolerances to ensure proper fit and optimal oil film thickness under high-stress operating conditions.
