Description
Features and Benefits
New-manufacture steel construction — not remanufactured or rebuilt — delivers full factory-grade strength and service life from day one with no unknown wear history.
33-spline inboard engagement matches OE specification exactly, ensuring proper torque transfer capacity for the heavy-duty demands of the Silverado 3500 HD drivetrain.
Rust-resistant coating protects the shaft from underbody corrosion, extending service life in the salt, moisture, and road debris environment these commercial trucks operate in.
Dimensionally matched at 37-2/16" inner shaft length for the Cab and Chassis body configuration — a platform with unique rear axle geometry not shared with standard body styles.
US Powertrain evaluates OE design for improvement opportunities, correcting known design limitations rather than simply duplicating original equipment specifications.
Backed by a 90-day warranty from US Powertrain, providing confidence in the replacement shaft's quality and fitment from the first mile after installation.
