6R140 Billet Intermediate Shafts

The factory intermediate shaft inside your 6.7L Super Duty's 6R140 transmission is fairly stout and can handle some amount of extra power, but it's also subjected to a ton of force and shock as your transmission shifts. At high enough power levels and extremely heavy towing applications, the factory cast steel intermediate shaft can really start to let your truck down. Tier One's 6R140 billet intermediate shafts are much stronger than stock, allowing them to handle massive levels of power, extreme towing applications, aggressive off-roading, and even hard track launches without cracking, bending, shearing its splines, or outright failing. These billet 6R140 intermediate shafts are the perfect choice for anyone who's going to be pushing their 6.7L Powerstroke build to the absolute limit.
