To combat the common problem of input shaft failure as power levels are increased in GM 4L60-4L70-E units, these three innovative heavy duty input shafts are an excellent fit for any high-horsepower street or strip application. Made of high strength steel which undergoes deep cryogenic treatment to achieve a very hard outer layer and a more ductile inner core, these shafts feature chamfered feed holes and shot peening to reduce stress and extend service life.
