Product Description

The ACL 4B1912HD-STD is a Race Series rod bearing set built for the Honda H22A4 2.2L DOHC VTEC engine found in the 1997-2001 Prelude. Its dowel-hole design locks each bearing into the rod cap for secure, rotation-free operation under high-load, high-RPM conditions, while the tri-metal copper-lead construction improves heat dissipation and oil film retention compared to stock bearings. It's a direct fit for engine builders doing a standard-size rebuild who want race-grade durability without altering journal dimensions.
