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. 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.
Some slip yokes have missing splines. To verify spline count, always count the splines on the transmission output shaft. A slip yoke counterbore is a short lead without spline in the end of the yoke.
