Dana Spicer 906550-1 1880 Series Short Couple Drive Shaft
The Dana Spicer 906550-1 Short Couple Drive Shaft is a genuine heavy-duty Spicer driveline assembly designed for applications where a compact driveshaft is required between closely spaced drivetrain components. Built around the Spicer 1880 Series, this short-coupled shaft is engineered to handle high torque loads while maintaining proper driveline alignment and smooth power transfer.
Dana manufactures its Spicer driveshaft assemblies to OE engineering, testing, and manufacturing standards. The 906550-1 uses heavy-duty steel construction and includes two universal joints, providing a complete short-couple assembly for compatible commercial truck and vocational drivetrain applications.

- Compact short-couple configuration for tight chassis layouts
- Two factory-specified universal joints
- Precision-engineered alignment and driveline geometry
- Steel construction for demanding commercial applications
- Up to 1 inch of total slip movement
- OE-quality Dana Spicer engineering and manufacturing

Application Note
Short-couple driveshaft assemblies are highly application-specific. Similar assemblies may differ in Spicer series, flange configuration, collapsed length, installed length, slip travel, or joint angle. Before ordering the Dana Spicer 906550-1, verify the 1880 Series designation, flange configuration, 13.618-inch collapsed flange-to-flange dimension, 14.118-inch installed dimension, and 1-inch maximum slip against the existing drivetrain assembly or vehicle parts information. The Dana Spicer 906550-1 is a genuine OE-quality short-couple driveshaft solution for heavy-duty truck and vocational applications requiring this specific compact 1880 Series configuration.
