The Dana Spicer 3-1-3191 (also listed as 313191) is a companion flange for heavy-duty driveline applications. Companion flanges serve as the interface between the driveshaft yoke and the mating component, such as a differential or transmission output, making correct part identification critical before ordering. This part is sold by Pro Gear and Transmission as a genuine Dana Spicer component. Because companion flanges vary by spline count, pilot diameter, and bolt circle, we recommend calling us to confirm this is the correct flange for your specific axle or transmission configuration before placing your order.
