T3-3-2431HP – Transmission Yokes – 1350 Series – 31/32 X 1.378 Splines – 1.886″ Hub Dia

Spec Summary: T3-3-2431HP -- 1350 Series | Short TH400 | Forged Chromoly | Black Oxide | 31/32-Spline x 1.378" | C/U-joint to End 5.500" | Hub 1.886" | No Counterbore

At 5.500" C/U-joint to end, T3-3-2431HP is the shortest chromoly TH400 yoke in the 1350 series range -- used in full-race drag cars where the chassis is built around a specific short driveshaft length. Compare with T3-3-5571HP (6.938") and T3-3-5551HP (7.940") if more slip travel is needed. The short yoke provides minimum driveshaft length, which raises the shaft's critical speed -- an advantage in high-RPM race applications where shaft whip is a concern.

The 31/32-spline profile confirms this is a TH400 fitment -- the TH400 uses a 32-spline output shaft, and the dual 31/32 count provides minor fitment flexibility. Forged chromoly handles the high shock loads present in drag race TH400 applications where transbrake launches produce instantaneous torque multiples of the engine's steady-state output. No counterbore -- output shaft engagement provides centering. Replace the TH400 output seal whenever the yoke is serviced.
