68RFE Input Shafts

6.7L Cummins Ram trucks can make a ton of power with relatively few modifications and tuning, but that doesn't mean the factory input shaft can handle it. The factory 68RFE input shaft can twist, shear, and fail in all sorts of spectacular ways when put under enough load, which is why jumping up to a high-performance 68RFE billet input shaft from Tier One is a great idea. These high-strength 68RFE input shafts can handle huge levels of power from hyper-aggressive Cummins tuning, big turbos, exhaust upgrades, and whatever else you throw on your truck. Our billet input shafts for 68RFE transmissions are the perfect insurance for taking your truck to the next level of performance without your input shaft letting you down.
