DRIVESHAFT

The Dana Spicer 170DS55011C-630M is a heavy-duty SPL170 series driveshaft assembly designed for commercial vehicle driveline systems. It features a 5.06-inch diameter steel tube with a 0.167-inch wall thickness. This component is engineered to handle the rigorous torque demands of Class 7 and Class 8 trucking applications.

The assembly offers a tube length of 630 mm (approx. 24.8 inches), a collapsed CL yoke-to-yoke length of 1001 mm (39.4 inches), and an installed length of 1056 mm (41.57 inches). It supports a maximum slip of 110 mm and is capable of maintaining functionality at joint angles up to 25 degrees.

Installation requires precise measurement of existing driveline configurations, including U-joint cap diameters, flange patterns, and overall drivetrain geometry. Because this part is chassis-specific rather than model-year specific, professional verification via vehicle build sheet or VIN through an authorized distributor is recommended before purchase.

This driveshaft is a replacement component for heavy-duty commercial vehicles, including those from manufacturers such as Freightliner, Kenworth, Peterbilt, Volvo, and Mack, provided the physical dimensions and torque rating requirements match the vehicle's original drivetrain specifications.
