ACL Bearings 4B2726HX-STD Race Series Rod Bearing Set Volvo B230

The ACL Bearings 4B2726HX-STD is a high-performance race series connecting rod bearing set designed specifically for Volvo B200, B204, B230, and B234 engines. These premium rod bearings feature standard sizing with increased oil clearance (HX designation) to accommodate high-performance and racing applications where precise oil film management is critical.

Race Series Engineering:

• High-strength overlay plate with reduced thickness for improved fatigue resistance
• Hardened steel backing on all rod bearings improves lining support and bearing retention
• Enhanced heat conduction through elimination of flash plating on bearing backs
• Increased eccentricity compensates for bore distortion at high RPM
• Superior material composition, dynamic thickness control, and optimized oil distribution
• Tight wall tolerances help maintain consistent bearing clearances

Key Specifications:

• Bearing Size: Standard (STD)
• Oil Clearance: HX (Extra clearance for performance applications)
• Bearing Half Type: Identical halves
• Bearing Material: F781 tri-metal construction
• Overall Length: 24mm (0.945 inches)

ACL Race Series bearings are engineered to withstand extreme conditions found in turbocharged, high-RPM, and racing applications. The unique combination of metallurgy, precision engineering, and quality control delivers the endurance and reliability that performance engine builders demand. These bearings offer significantly higher load capacity than OEM bearings, making them an essential upgrade for engine tuning and motorsports applications.
