Sonnax performance slip yoke T3-3-3931HP is an excellent upgrade over factory-style yokes. Forged from a chromoly billet and machined with precision, this yoke provides superior strength and durability at an affordable price and fits a variety of applications, including those listed here. Perfectly suited for high horsepower and torque capacity vehicles, whether at the strip, on the street or at the track.
Compatible with the popular “Viper / Aston Martin” 30-spline T56 output shaft.
Measure OE slip yoke with a precision tool to determine which Sonnax yoke you need. Length, journal size and U-joint series are critical dimensions requiring accurate measurements.
*U-joint bores in yoke will be slightly larger than the actual U-joint dimensions given in the chart below.
