A Spicer yoke ruler assists technicians to measure a driveshaft yoke and determine the series of the driveshaft, which will then help them find the correct Spicer u-joint kit for that series.

“Spicer u-joints are engineered to ensure peak performance,” said Bill Nunnery, senior director, sales and marketing, global aftermarket for Dana.  “On the road or in the lab, they consistently outperform the competition. The Spicer yoke ruler is designed to help service technicians and consumers choose the right u-joint for their driveshaft installation.”

Once the driveshaft/u-joint series has been determined, technicians should refer to the Common U-Joints by Series Chart to see the options that are available for light- and medium-duty vehicles and commercial vehicles to easily identify the appropriate Spicer u-joint kit part number.
