6.125″ 2.100″ Journal .927″ Pin Ultra H Connecting Rod Set for 03-24 5.7/6.1/6.2/6.4L HEMI U16100 By Callies

You know that one friend who can bench 600 lbs and still carry all the groceries in one trip? That’s basically what the Callies U16100 Ultra H Connecting Rods are for your HEMI. Whether you’re building for boost, nitrous, or just trying to hit “ludicrous mode” with a naturally aspirated setup, these rods are the kind of muscle you need.

Designed for 5.7L, 6.1L, 6.2L, and 6.4L HEMI engines (from 2003 through the future), this rod set features a 6.125″ center-to-center length, 2.100″ big end journal, and a .927″ wrist pin—which is pretty much the secret handshake of all serious HEMI builders.

Made from high-strength, forged steel and part of Callies’ Ultra H series, these rods are like gym rats for your engine—except they don’t skip leg day, they are leg day. Precision-machined, track-proven, and trusted by engine builders who actually know what they’re doing, this set is ready for high RPM abuse and the kind of horsepower that makes tires cry.

Also, we should mention: these rods don’t come with any “go easy on me” warnings. They’re here to party. If you’re still using stock rods while trying to make big power, we kindly suggest you reconsider your life choices (or at least your rotating assembly).

Bottom line? Callies U16100 rods are tough, proven, and ready to get rowdy with your HEMI. Let’s build something stupid fast.
