47RE Input Shafts

One the weak points of the stock 47RE transmission is the factory input shaft, which can twist, shear, or wreck its splines when you start throwing extra power and torque on your awesome Ram truck. Tier One's selection of 47RE billet input shafts can handle far more power than stock, letting you add aggressive tuning, big turbos, oversized injectors, exhaust upgrades, and whatever other power-adders your truck needs without your input shaft letting you down. These billet input shafts are far more resistant to failures and keeps your 47RE transmission in great shape, even if you're towing heavy, doing aggressive track launches, or ripping around off-road on big tires.
