Show original supplier description
The Xcalliber Allison Billet Performance Input Shaft is engineered for demanding high-power Allison 1000 transmissions, catering to Duramax owners who push their vehicles through frequent 4WD launches and drag racing. Constructed from robust 9310 vacuum-elted billet steel, this shaft is built to withstand high torque and horsepower situations, ensuring your transmission remains intact under extreme conditions. Key features include a corrosion-resistant Black Oxide coating for durability, a larger turbine spline for enhanced strength, and a shot-peening process to reduce brittleness. It also includes a late teflon-lined Garlock bushing and comes with one billet 4WD input shaft. A DmaxStore note indicates that earlier model year trucks from 2001-2005 may require machining of the C1 hub or an update to a later style C1 hub for proper fitment of this billet input shaft.
