202990-3 – Short Couple Driveshafts – 1480 (1.375 x 4.188) Series – 9.500″ Flange to Flange

202990-3 1480 Series Short Couple Driveshaft 9.500" Flange to Flange

The 202990-3 is a 1480 series short couple driveshaft with a 9.500" flange-to-flange length and 5.500" centerline-to-centerline dimension. The 1480 series uses 1.375" cap diameter trunnions on a 4.188" span — one step below 1550 in the SAE torque hierarchy.

Specifications

• Part Number: 202990-3
• Series: 1480 (1.375" x 4.188")
• Flange to Flange: 9.500"
• CL to CL: 5.500"

When fitting the 202990-3, confirm the installed flange-to-flange gap is 9.500". The 4.000" differential between F-to-F and CL-to-CL is consistent with standard 1480 flange yoke CJ-to-flat dimensions. Both end flanges must accept 1480 series U-joint cap bores (1.375" diameter, 4.188" span).

Note that 1480 and 1550 series both share a 1.375" cap diameter, but the cap span differs: 4.188" for 1480 versus 4.964" for 1550. A 1480 U-joint installed in a 1550 yoke bore will have 0.776" of lateral play in the cap slots — verify series compatibility by checking cap span, not just diameter, before substituting hardware.
