48RE Input Shafts

The stock input shaft on your 48RE may be fine at stock levels of power of if you're not pulling anything heavy, but if you're looking to take your Ram to the next level of performance or tow big trailers, adding a better 48RE input shaft to your rig should be high on your list. We here at Tier One offer high-strength 48RE billet input shafts that can handle huge levels of horsepower and torque, extremely hard launches at the track, and very heavy towing without letting your truck down. These input shafts are resistant to twisting, shearing, and stripping their splines when placed under huge levels of load, making them perfect for Ram trucks that are stacked with aggressive tuning, big turbos, oversized injectors, exhaust upgrades, and whatever else you want to throw on your Ram truck build.
