9in Degree Wheel

The PROFORM 9in Degree Wheel is an essential diagnostic and tuning instrument for engine builders looking to achieve precise valve timing and crankshaft positioning. This tool is particularly useful for those assembling high-performance racing engines or performing standard cam swaps, providing the accuracy needed to verify camshaft specifications against the manufacturer’s data sheet.

Manufactured from durable steel, this 9-inch diameter wheel features a high-contrast white paint finish that ensures maximum legibility in dimly lit environments. The large diameter provides greater resolution between degree marks, making it easier to read fine adjustments when checking lobe lift or duration. The white background paired with black markings allows for quick visual confirmation of timing events, reducing the risk of parallax error during the measurement process.

This robust construction ensures the tool maintains its flat profile even after repeated use in a professional workshop setting. It is a critical addition for any technician looking to buy professional-grade engine building equipment. The degree wheel is compatible with a wide range of crankshafts, typically requiring a crankshaft snout for proper alignment.
