ACL Bearings 6B2630H-.025 Race Series Rod Bearing Set Nissan RB20

ACL Race Series 6B2630H-.025 connecting rod bearing set is engineered for high-performance Nissan RB20DE and RB20DET engines with reground crankshafts. This .025mm undersize bearing set is designed for crankshafts that have been machined undersize and provides the precision fit required for race and high-performance street applications.

Performance Features:

• Tri-metal construction with hardened steel backing for maximum strength under high RPM and load conditions
• High-strength lead-tin-copper overlay plate with reduced thickness for improved fatigue resistance
• Precision machined to tight wall tolerances ensuring consistent clearances and reliable fit
• Layers of nickel barrier and high-fatigue-strength copper-lead lining
• No flash plating on bearing backs for improved heat transfer and bearing retention
• Increased eccentricity to compensate for bore distortion at high RPM
• Enlarged ID chamfers on bearing edges to accommodate performance crankshafts with larger fillets
• 3/4 groove design provides optimum oil supply while maximizing load carrying capacity

ACL Race Series bearings are manufactured to exacting tolerances with micron-level precision, delivering the dependability required for high-performance and racing applications. Complete set includes bearings for one engine. Note: ACL Race Series bearings do not have the typical silver-grey appearance due to the elimination of tin flash plating—this is a performance feature, not a defect.
