When fitting the 3-3-3931X, confirm the Viper transmission output shaft carries 29 or 30 splines at 1.326" diameter. The 6.630" CL-to-end is shorter than many heavy-duty transmission yokes, reflecting the compact driveline packaging of the Viper. The 1.681" hub diameter contacts the transmission tail housing seal — confirm seal bore dimensions and that no counter bore is required at the shaft tip. The 3-3-3931X is a 1350 series yoke; all U-joints and companion yokes in this Viper driveline application must also be 1350 series. The 1.326" spline diameter on the 3-3-3931X differs from the 1.284" of the 2-3-14031X and 1.391" of the 2-3-10201X — confirm the exact spline diameter before ordering. Count tailshaft splines (29 vs. 30) and verify 1.326" diameter before ordering the 3-3-3931X.
