Stop Twisting Shafts And Start Building Real Strength

If you’re putting serious power through your 1994–2007 Dodge RAM 2500 or 3500 with a 5.9L Cummins, you know the factory input shaft won’t always keep up. Whether you're towing heavy, launching hard, or just building a high-horsepower setup, the BD Diesel Billet Input Shaft is one of those upgrades that pays off the first time your foot hits the floor. Made from ultra-strong 300 Maraging steel, this shaft is designed to take the kind of shock load that would leave a stock shaft in pieces. It’s a smart investment for anyone who doesn’t want to be stranded with transmission problems after turning up the power. The best part is, it’s built with drop-in precision, so you don’t have to fight with fitment or compatibility. Pair it with billet output and intermediate shafts and you’ve got a transmission that’s ready to handle nearly anything. If you’re building for power and peace of mind, this is the place to start.

Built With Precision To Handle High Torque Loads

The BD Diesel 1600115 Billet Input Shaft is engineered specifically for the torque demands of the 1994–2007 Dodge RAM 2500 and 3500 5.9L Cummins. Manufactured from 300 Maraging steel, this high-grade material is known for its extreme tensile strength and resistance to twisting under load. That makes it ideal for heavy towing, performance upgrades, and modified trucks pushing higher horsepower than stock drivetrains were designed to support. This shaft is precision machined to ensure proper fit with factory components, helping maintain smooth engagement while withstanding the shock of aggressive throttle and load changes. BD Diesel developed this shaft to serve as the foundation of a more durable transmission setup, particularly when paired with billet output and intermediate shafts. It’s backed by a 12-month or 12,000-mile parts warranty and is legal for use in all 50 states, making it a reliable and emissions-compliant upgrade. However, it's worth noting that race abuse is not covered under warranty, which speaks to the kind of power this shaft is expected to handle.
