Ultra Enforcer Connecting Rods U14245 6.200 Length, 2.100″, .927″ By Callies

If connecting rods were superheroes, the Callies Ultra Enforcer rods would wear a cape and punch horsepower in the face. These bad boys are forged from ultra-clean TimkenSteel, made to Callies’ own specs—not the kind of off-the-shelf stuff you melt down lawnmowers to make. We’re talking proprietary, purpose-built steel, forged in Trenton, Michigan and finished with love (and a lot of precision) in Fostoria, Ohio.

What does that mean for you? It means confidence. Confidence that your rods won’t flinch when you’re pushing your engine to the moon. Confidence that each one has been obsessively tracked through every stage of its build process like a toddler with a juice box in a room full of white carpet. Each Ultra Enforcer rod has a detailed manufacturing history, and the team at Callies isn’t shy about making sure every piece that leaves the shop meets their sky-high standards.

And let’s be real—you didn’t build your engine just to cruise to the grocery store at 35 mph (unless your grocery list includes “more race fuel”). These rods are meant to take punishment and ask for seconds. Whether you’re building a strip monster, a street beast, or something in between, Callies gives you the confidence to rev it like you mean it.

So if you’re chasing reliability, quality, and American-made performance that won’t flake under pressure—this is your rod. Bonus: no cape included, but we’re working on it.
