906224-4 – Short Couple Driveshaft – 1610 (1.875 x 5.312) Series – 9.880″ Flange To Flange

906224-4 Short Couple Driveshaft — 1610 Series, 9.880" Flange to Flange, 6.120" CL to CL

The 906224-4 is a 1610 Series short-couple driveshaft assembly with a flange-to-flange dimension of 9.880" and a centerline-to-centerline U-joint distance of 6.120". The 1610 Series uses 1.875" cap diameter U-joints with a 5.312" cross width, placing it one series below the 1710 in the SAE torque hierarchy. This assembly is designed for heavy-duty commercial vehicle interaxle and short-coupled applications in the Class 6–7 range, as well as vocational and off-highway equipment where 1610 Series drivetrain components are specified. Factory balanced prior to shipment.

The 906224 family is defined by both flange-to-flange and CL-to-CL dimensions, which together characterize the complete installed geometry. The 906224-4 at 9.880" F-to-F and 6.120" CL-to-CL represents a specific yoke body depth and assembly length combination. The 3.760" difference between F-to-F and CL-to-CL reflects the combined depth of both flange yoke bodies — each yoke body adds approximately 1.880" from the flange face to the U-joint cross centerline. Both dimensions should be verified against the vehicle measurement when selecting this assembly.

Fitment & Installation Notes

Before ordering the 906224-4, measure the flange-to-flange gap between companion flanges in the vehicle. The 1610 Series companion flange bolt circle, pilot diameter, bolt count, and bolt diameter must be confirmed against the axle or transmission manufacturer's specifications. The 1610 Series U-joint cap (1.875") will not fit correctly in 1710-bored yoke ears (1.938") — if the vehicle has been upgraded or has mixed series hardware, verify the companion flange bore size before ordering. Short-couple driveshafts have no slip range; the 9.880" F-to-F is the fixed installed dimension.

The 1610 Series is catalogued for Class 6 medium-duty trucks, certain Class 7 vehicles, and heavy vocational equipment where the driveline torque requirement falls below the 1710 rating threshold. The 1.875" cap diameter and 5.312" span are distinctly smaller than the 1710 Series (1.938" cap, 6.094" span) — these series are not cross-compatible. The factory balance ensures the 906224-4 operates within commercial vehicle vibration limits at rated operating speed for the 1610 Series application range.

The 906224-4 is one of three primary length variants in the 906224 1610 Series family (along with the 906224-1 at 9.120" and 906224-5 at 10.000" F-to-F). Select based on the measured flange-to-flange gap in the vehicle.
