ACL Race Main Bearings Set – Audi DAZA/DNWA 2.5T FSI

Overview

ACL Race Series Main Bearings are engineered for performance and reliability under high-load, high-RPM conditions. Whether you're building a high-boost street car or a full-time track weapon, ACL bearings offer industry-leading strength, oil control, and durability.

This listing includes both the standard clearance (6M5587H-STD) and the extra oil clearance variant (6M5587HX-STD) to suit your specific crankshaft and bearing tolerance needs. Both options feature tri-metal construction, hardened steel backing, and race-proven geometry for consistent performance where OEM bearings fall short.

Key Features

• Available in Standard or Extra Oil Clearance for tailored engine builds
• Tri-metal bearing construction with hardened steel backing
• High-strength overlay with reduced thickness for fatigue resistance

• Increased eccentricity compensates for bore distortion at high RPM
• Flash plating eliminated on the back for better heat transfer and housing grip
