    Heavy Duty Input Shafts

    Fits 300mm reluctor-style units only.

    Input shaft failure is a common problem in GM 4L60-E, 4L65-E and 4L70-E units as power levels are increased. Sonnax heavy duty input shaft 77733-12S for 300mm reluctor-style units is made of specially heat treated steel with very hard outer layers with a more ductile inner core for strength and resistance to fracture. The feed holes are chamfered to reduce stress and the shaft is further processed by shot peening and deep cryogenic treatment. This shaft is suitable for any high-horsepower street or strip application.

    • High strength material for high performance applications
    • Chamfered feed holes and shot peening reduce stress cracks and increase service life
    • Deep cryogenic treatment for additional toughness
