DRIVESHAFT (STEEL)

The Dana 350DS55002F-1260M is a heavy-duty driveshaft assembly belonging to the Spicer SPL® 350 series. Engineered for commercial on-highway applications, this High Power Density™ (HPD™) unit is designed to handle the increased torque demands of modern engine downspeeding. The assembly is built for extended durability, supporting maintenance cycles of up to 1 million miles in professional trucking operations.

As a component of the Spicer SPL® 350 series, this assembly features a compact, high-performance design that prioritizes weight reduction while maintaining structural integrity. It is intended to minimize vibration and maximize drivetrain efficiency across long-haul environments.

Fitment for this component is not determined by standard year/make/model cataloging. Each application requires a specific VIN-based analysis to ensure correct shaft length, flange bolt patterns, and spline dimensions. It is compatible with a wide array of heavy-duty chassis configurations typically found in Class 8 trucks.

Installation should be performed by qualified commercial vehicle technicians. Proper driveline phasing and angle alignment are critical to preventing premature wear and vibration issues. This part is a professional-grade component and should be serviced according to the manufacturer's heavy-duty maintenance protocols.
