ACL Bearings 5B2290A-1.00 Connecting Rod Bearing Set Oversize - 1.00mm

The ACL Bearings 5B2290A-1.00 is a performance connecting rod bearing set designed for precision engine builds and rebuilds. These conrod bearings feature a 1.00mm oversize specification, making them ideal for machined crankshafts that require oversized bearings to restore proper clearances.

Key Features:

• 1.00mm oversize for machined crankshaft journals
• High-performance tri-metal construction for superior durability
• Precision-engineered for consistent oil clearances
• Advanced bearing materials resist fatigue and wear
• Complete set for one connecting rod assembly
• Manufactured to OE or better specifications

ACL Race Series bearings are engineered with racing-derived technology including optimized bearing profiles, enhanced material composition, and tighter manufacturing tolerances. The tri-metal design typically features a steel backing, copper-lead intermediate layer, and a specialized overlay for excellent conformability, embeddability, and resistance to corrosion. These bearings are suitable for both high-performance street applications and professional racing engines where reliability under extreme loads is critical.
