Features and Benefits
Newly manufactured steel construction — not a remanufactured core — delivers fresh metallurgical integrity free from the fatigue cracks and wear inherent in used axle shafts.
28 inboard splines machined to factory specification ensure full, positive engagement with the differential carrier for reliable torque transfer to the rear wheel.
27-1/4 in. shaft length matches the original equipment dimension for a direct-fit installation on 1974-1975 Ford Bronco rear axles — no cutting, welding, or modification required.
Rust-resistant coating applied to shaft body protects against surface corrosion during storage and service life — especially important for vintage vehicles with extended time between drives.
Engineered with OEM design review — US Powertrain identifies and corrects known factory design flaws during manufacturing, so you receive a shaft that improves on the original specification.
Made in the USA — manufactured domestically for quality oversight and consistency you can count on for a hard-to-find classic truck application.
