H-Series Connecting Rod Bearing 0.020 in Undersize

The Calico Coatings CB663HN20 is a H-Series connecting rod bearing designed for high-performance applications in Small Block Chevy and GM LS-Series engines. This specific bearing is 0.020 inches undersize, has a narrowed profile, and is coated with Calico's CT-1 Dry Film Lubricant. Constructed with a tri-metal design, these bearings offer proven durability and are built to handle sustained combustion pressures. The H-Series bearings also feature enlarged chamfers for improved oil flow and a high crush factor for a secure fit. They utilize hardened-steel backings with thin overlays, characteristic of Clevite H-Series bearings.
