ACL Bearings 4B1351-.75 Connecting Rod Bearing Set Undersize - 0.75mm

The ACL Bearings 4B1351-.75 is a precision-engineered connecting rod bearing set designed for 4-cylinder engines with crankshafts ground 0.75mm (0.030") undersize. ACL bearings are manufactured with advanced metallurgy and strict dimensional tolerances to provide reliable performance in both OEM replacement and performance applications.

Key Features:

• 0.75mm (0.030") undersize for reground crankshafts
• High-strength steel backing for enhanced support and retention
• Precision-ground bearing surfaces for optimal oil film formation
• Improved heat dissipation through enhanced thermal transfer design
• Consistent wall thickness for reliable bearing clearances
• Complete set for one engine rebuild

ACL bearings feature advanced design elements including increased eccentricity to compensate for bore distortion at high RPM and elimination of flash plating on the bearing backs to improve heat transfer and maximize grip in the housing. These bearings are suitable for street, performance, and racing applications where durability and precision are essential.
