Pro Degree Wheel - 16in

The Pro Degree Wheel – 16in is a precision timing tool essential for any serious engine builder, tuner, or performance mechanic. Whether you're dialing in ignition timing, verifying TDC (top dead center), or setting up a new crank trigger system, this 16-inch aluminum degree wheel provides the accuracy needed for repeatable, professional results. Designed for use on engine blocks during assembly or rebuild, it allows you to mark exact crankshaft positions and establish baseline references for fuel injection and ignition mapping.

Machined from durable aluminum and finished in blue anodize, the Pro Degree Wheel features clearly marked degree increments around its 16-inch diameter face, making it easy to read and reference from multiple angles. The blue anodized coating resists corrosion and provides excellent contrast for visibility under shop lighting, while the lightweight construction at 2.84 lbs makes it portable without sacrificing rigidity. The large diameter ensures consistent, accurate measurements across the full stroke, critical for engines where even a single degree of misalignment can affect startup timing, idle quality, and peak power delivery.

This degree wheel suits small-block and mid-sized engine platforms, fitting standard crankshaft snouts on most domestic and import applications. It is indispensable during engine swaps, stroker builds, and forced-induction conversions where OEM timing references no longer apply. Professional engine shops, transmission builders preparing engine control modules, and enthusiasts performing nitrous or supercharger tune-ups all rely on precision degree wheels to establish the foundation for safe, repeatable performance. Keep one in your shop for every major engine project.
