ATI Performance Output Shafts

ATI Performance Products® is proud to introduce two new output shafts and an extension housing for 4L80E and 4L85E transmissions. These new shafts are made from 300M material, with a 4140HT splined hub, rated to over 1,500 horsepower, and are 100-percent made in house. When used with the ATI heavy duty cast aluminum roller bearing tail housing, it makes your 4L85E the same length as a T400 transmission - allowing for easier swaps and fitment. ATI’s 2-piece 300M Output Shafts will work with OEM and aftermarket cases.
