ACL Bearings 4B2746H-.025 High Performance Rod Bearing Set Oversized - 025mm

The ACL Bearings 4B2746H-.025 is a high-performance connecting rod bearing set designed for the Nissan KA24DE 2389cc inline 4-cylinder engine, featuring a .025mm oversized specification for use with reground crankshafts. This trimetal bearing construction combines advanced design, metallurgy, and engineering to deliver exceptional durability in demanding performance applications.

Key Features:

• High-strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backing on all rod bearings for enhanced support and bearing retention
• Increased crush design improves retention through higher radial contact pressures and heat dissipation
• Elimination of flash plating on bearing backs maximizes heat transfer and grip
• Increased eccentricity compensates for bore distortion at high RPM and assists hydrodynamic oil film formation
• Precision manufacturing with micron tolerance machining ensures consistent wall thickness and crush

ACL Race Series engine bearings are engineered to withstand higher RPM conditions, making them ideal for performance builds, racing applications, and engine rebuilds requiring oversized bearings. ACL Race Series bearings are recognized throughout the motorsports world and are standard components in race engines from drift racing to professional competition.

Application: Compatible with Nissan KA24DE and KA24E engines found in 240SX, Altima, Frontier, D21, Pickup, Xterra, and other models. The .025mm oversized specification is designed for crankshafts that have been ground .025mm undersize.
