AMC-Schou CRA-2 Connecting Rod Aligner

The AMC-Schou CRA-2 is a precision rod-aligning tool designed for engine builders and machinists who need to quickly and accurately check and correct bend, twist, or offset in connecting rods. It handles rods up to 18.1-inch in length – covering most automotive and light industrial rods – and includes all necessary bending/twisting tools. Because it’s simple to use and doesn’t require additional instruments, the CRA-2 is a great shop-floor addition for rebuilding rods and ensuring proper alignment before assembly or machining.

Built on Real Engine-Rebuilding Experience

Decades before today’s engine shops trusted our equipment, Tony was already deep in the craft — rebuilding motors, machining blocks, and pushing for better precision.

A local newspaper once featured him as a standout young machinist, noting his drive, attention to detail, and obsession with doing things the right way. That same passion would eventually shape our company’s values.

Today, that commitment lives on in every machine we sell, every customer we support, and every shop we help succeed.
