T2-3-5981HP – Transmission Yokes – 27/28 X 1.220 Splines – 1330 Series – 1.500″ Hub Dia

The T2-3-5981HP transmission yoke is the connection between the gearbox tailshaft and the front of the driveshaft. It splines onto the transmission output shaft and carries the front u-joint of the driveshaft. For 1330 series applications, the spline count and hub diameter are the two specs that determine whether this part fits your tailshaft correctly.

T2-3-5981Hp Transmission Yoke — 1330 Series Specs & Tailshaft Fit

The 1330 series covers light-to-medium duty trucks and GM half-ton platforms. The T2-3-5981HP transmission yoke specs: 27/28 X 1.220 spline | 1.500" hub | 5.906" CJ-to-end. Compatible with: C4 / Forged Steel / Black Oxidized / CHROMOLY. Hub diameter determines engagement depth on the tailshaft — if the hub is too short, the splines don't fully engage. CJ-to-end affects driveshaft working length.

After a transmission rebuild or swap, confirm the tailshaft spline count hasn't changed before installing the T2-3-5981HP transmission yoke. Not all 1330 series transmissions use the same output spline across all years and configurations. Count the splines on the actual shaft.
