2001-2016 GM 6.6L Duramax Billet Input Shaft
The transmission input shaft is tasked with transferring the horsepower from the torque converter to the transmission. Due to its placement,the part needs to be tough because it is subjected to a huge amount of twisting torque._x000D_
The PPE Billet Input Shaft has been specially designed to withstand higher horsepower and torque levels (over 800 RWHP) that come with high-performance engines or the added stress that comes with towing or racing. This shaft is highly recommended when installing our Stage4, Stage5 and Stage6 transmission kits.
