Product Description
The ATS 304-910-4248 Allison Billet Input Shaft is a critical upgrade for strengthening the factory Allison 1000 transmission in 2001-2016 6.6L Duramax trucks. Designed to handle increased horsepower and torque, this billet input shaft eliminates one of the most common failure points in high-performance and towing applications.
The factory input shaft is prone to twisting or breaking under heavy load, especially in tuned or modified trucks. ATS addresses this issue with a precision-machined billet shaft engineered for superior strength, durability, and long-term reliability.
Whether you're building a high-horsepower Duramax or simply want added confidence when towing heavy loads, this billet input shaft provides the reinforcement needed to keep your Allison transmission performing at its best.
FAQ
