Output shaft failure is common as power levels are increased in GM 4L60-E, 4L65-E and 4L70-E units. Sonnax heavy duty output shaft 74678S-HD for 4WD/AWD units is precision engineered and manufactured for unbeatable performance in high-horsepower street and strip builds. The shaft features many unique refinements available only from Sonnax, including a torsional design that allows energy to be absorbed, reducing peak loads to critical areas.
