Spicer Diamond Series Driveshafts

Dana's Spicer Diamond Series Driveshafts increase payload by pairing industry-proven SPL universal-joint technology with an aluminum tube. Under real-world test conditions of more than a year and 750,000 miles later, no issues with the driveshafts were reported, including no balance problems, maintenance concerns or other complaints. The driveshaft combines dissimilar metals, successfully pairing steel end fittings with a single-piece, high-strength aluminum tube, eliminating the need for a center bearing used in traditional two-piece driveshafts, reducing component wear and installation costs. As a result, this technology weighs up to 40 percent less, improving fuel economy and load-carrying capacity.
