Diamond Series Driveshafts

Introduced by Peterbilt (Paccar) for heavy hauler and vocational applications, Dana's Spicer® Diamond Series™ is an industry first one-piece aluminum driveshaft that allows truck owners to save up to 100 pounds per vehicle. Dana developed a hydro-formed football shape and adapted rocket science joining techniques to weld lightweight aluminum tubes to durable steel end fittings removing up to 36% of a HD truck's traditional two-piece driveshaft weight and simplifying assembly line installation.
