ACL Bearings 8B1442HX-STD Race Series Connecting Rod Bearing - Set

ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world. The HX designation provides an extra 0.001" (0.025mm) oil clearance on standard size journals, with bearing walls that are 0.0005" (0.013mm) thinner than standard H-series bearings.

Key Features:

• Designed to withstand higher RPM conditions with high-strength overlay plate and reduced thickness for improved fatigue properties
• Hardened steel backs on all rod bearings improve support of the bearing lining and assist with bearing retention in the housing
• Increased crush for improved bearing retention
• Elimination of flash plating on the back of bearings improves heat transfer and maximizes grip between bearings and housing
• Increased eccentricity compensates for bore distortion at high RPM and assists in formation of hydrodynamic oil films
• Tight consistent wall tolerances help maintain consistent clearances
• Tri-metal construction for optimal strength and durability

The unique combination of design, metallurgy and engineering provides Race Series performance bearings with the endurance and capability to perform where others cannot. Standard size with extra oil clearance makes these bearings ideal for high-performance builds requiring precise clearance control.
