Product Details and Specifications

The Dorman 946-337 drive shaft is designed specifically for use with Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. Its aluminum construction reduces rotational mass, which can contribute to improved fuel efficiency and smoother driveline operation. The 4-inch diameter shaft and 0.083-inch wall thickness provide a solid balance between strength and weight. This drive shaft features a slip yoke to accommodate driveline movement and vibration, but it does not include CV joints or an axle nut, so those components must be sourced separately if needed. The fixed length of 75.375 inches means it is designed for direct replacement without adjustment.
