906224-1 – Short Couple Driveshaft – 1610 (1.875 x 5.312) Series – 9.120″ Flange To Flange

906224-1 Short Couple Driveshaft — 1610 Series, 9.120" Flange to Flange, 5.380" CL to CL

The 906224-1 is a 1610 Series short-couple driveshaft assembly with a flange-to-flange measurement of 9.120" and a centerline-to-centerline U-joint distance of 5.380". The 1610 Series employs 1.875" cap diameter U-joints with a 5.312" cross width, providing the torque capacity required for medium and heavy-duty commercial vehicle applications. This assembly is used in interaxle and short-coupled flanged configurations where the companion flange gap measures 9.120". Factory balanced prior to shipment.

The 906224-1 at 9.120" F-to-F and 5.380" CL-to-CL is the shortest variant in the 906224 flanged 1610 Series family. The 3.740" difference between F-to-F (9.120") and CL-to-CL (5.380") represents the combined depth of the two flange yoke bodies — approximately 1.870" per end from flange face to U-joint cross centerline. The 906224-1 at 5.380" CL-to-CL is distinctly shorter than the 906224-4 (6.120" CL-to-CL) and 906224-5 (also 5.380" CL-to-CL at 10.000" F-to-F), reflecting that the -5 variant uses longer yoke bodies at a different F-to-F.

Fitment & Installation Notes

Measure the flange-to-flange gap in the vehicle before ordering the 906224-1. The 9.120" F-to-F positions this as the shortest in the 906224 family — the next longer variant is 906224-4 at 9.880" (0.760" longer). If the chassis gap is between these two values, the exact variant cannot be substituted without modifying the installation, so the measurement must be taken at the flange face locations with the axles positioned at their operating load height. The 1610 Series companion flange dimensions must be confirmed per the axle OEM documentation.

The 1610 Series occupies the torque range between the 1480 (1.375" cap) and 1710 (1.938" cap) series in the heavy commercial driveline hierarchy. It is catalogued for Class 6 trucks, certain Class 7 vocational vehicles, and heavy-duty agriculture and construction equipment where the torque rating falls within the 1610 range. Short-couple driveshafts in this series do not accommodate driveshaft length variation — the 9.120" F-to-F is a fixed installed dimension, and companion flanges must be clean and undamaged to ensure correct torque transmission.

The 906224-1 is the shortest flanged variant in the 906224 1610 Series family. All variants use the same 1610 Series U-joint and flange yoke design. Verify the 9.120" flange-to-flange measurement against the vehicle chassis specification before ordering.
