207785-1 1550 Series Short Couple Driveshaft 9.500" Flange to Flange

The 207785-1 is a 1550 series short couple driveshaft with a 9.500" flange-to-flange length and 5.500" centerline-to-centerline dimension. The 1550 series uses 1.375" cap diameter trunnions on a 4.964" span.

Specifications

• Part Number: 207785-1
• Series: 1550 (1.375" x 4.964")
• Flange to Flange: 9.500"
• CL to CL: 5.500"

When fitting the 207785-1, confirm the installed flange-to-flange gap is 9.500" with both flanges fully seated. The 4.000" differential between F-to-F and CL-to-CL is consistent with standard 1550 flange yoke CJ-to-flat geometry. Both end flanges must accept 1550 series U-joint cap bores.

Note that the 204249-5 also measures 9.500" F-to-F and 5.500" CL-to-CL within the 1550 series. The 207785-1 and 204249-5 share identical installed dimensions but carry different part numbers — confirm which part number your OEM or existing driveshaft references before ordering. Both require 1550 series U-joints at both ends.
