H-Series Rod Bearings CB-663HN By Clevite

You’ve got Callies rods in your Gen 3 HEMI? Good choice. Now give them the sidekick they deserve—Clevite CB-663HN H-Series Rod Bearings, the engine world’s equivalent of a rock-solid best friend. You know, the one who actually shows up on moving day.

Originally cooked up for high-stress racing like NASCAR (yeah, that NASCAR), these bearings are built for engines that laugh in the face of high RPMs. They’re like the bouncers of the bottom end—strong, consistent, and always keeping things in line.

Made with Clevite’s tri-metal construction, they deliver exceptional fatigue strength, wear resistance, and load capacity. That means your crank can spin to the moon and back (figuratively—don’t actually launch it), and these bearings will keep things smooth and drama-free. They’re also flash-free for proper seating and feature just the right amount of eccentricity to keep oil where it should be—between metal, not on your garage floor.

These babies are a match made in horsepower heaven for Gen 3 HEMIs running Callies connecting rods. Whether you’re drag racing, street cruising, or just chasing that elusive perfect build, these bearings are the unsung heroes behind the scenes making sure your rotating assembly stays together like a sitcom family by the end of an episode.

So skip the cheap stuff and go with the bearing that’s been tested on track and trusted by pros. Your engine—and your right foot—will thank you.
