Product Description

The ACL 4B1946HXD-STD is a Race Series rod bearing set built for the B18A1/B18B1 non-VTEC engine used across the 1990-2001 Acura Integra. The dowel-hole design locks each bearing into the rod cap for secure, rotation-free operation, while the added 0.001" clearance and tri-metal copper-lead construction improve oil film stability and heat dissipation for high-RPM or forced-induction builds. It's a direct-fit upgrade for standard-size rebuilds where added durability over stock bearings is the priority.
