BD Diesel Billet Input Shaft Ford 1999-2010 4R100/5R110

This BD Diesel Billet Input Shaft is crafted from 300M and 300 Maraging steel, materials known for their exceptional strength and resilience. This is a critical upgrade for Ford trucks equipped with the 4R100 or 5R110 transmissions, especially those pushing beyond 500 rear-wheel horsepower or regularly towing heavy loads. The stock input shaft can become a weak point under extreme stress, but this billet shaft is designed to significantly increase the durability of your transmission, helping it withstand the demands of high-performance applications.

When you're dealing with significant power increases, whether from engine modifications or the use of a high-stall torque converter like BD Diesel's Triple Torque Force converter, the forces transmitted through the drivetrain become immense. This billet input shaft is engineered to absorb those shocks and stresses, preventing premature failure. It's a well-built component that directly addresses the potential failure points in a high-horsepower drivetrain, offering peace of mind for serious truck owners. This part fits a wide range of Ford Super Duty trucks, vans, and SUVs from 1999 through 2010, including models like the F-250 Super Duty, F-350 Super Duty, and Ford Excursion.

BD Diesel backs this billet input shaft with a 12-month or 12,000-mile warranty, covering manufacturing defects under normal use. It's important to note that this warranty does not extend to race abuse. For those with less aggressive setups, replacement stock shafts and hubs are also available, but for maximum durability under demanding conditions, this billet shaft is the recommended choice.
