T3-3-6081HP – Transmission Yokes – 1350 Series – 26/27 X 1.176 Splines – 1.500″ Hub Dia

T3-3-6081HP -- Forged Chromoly 1350 Series TH350 Yoke, 26/27-Spline

The TH350 is among the most common transmissions used in GM muscle car and street rod applications -- the 26/27-spline x 1.156" output is the standard TH350 output profile. Upgrading from a 1310 to 1350 series yoke on a TH350 with a high-performance rebuild requires changing both the yoke and the driveshaft's tube yoke/weld yoke to the 1350 series; a mixed-series driveshaft is a common failure point in high-power builds.

The forged chromoly construction on T3-3-6081HP tolerates higher impact loads than cast iron or machined mild steel -- critical for drag launch applications where the torque spike at the 1-2 shift can exceed steady-state values by 3-5x. Black oxide finish provides basic corrosion protection. The 5.469" C/U-joint to end is the HP (high performance) version at slightly different length than the standard T3-3-6081H (5.810") -- confirm which length is correct for your specific TH350 application before ordering.
