Features and Benefits
Newly manufactured steel construction — not remanufactured or reconditioned — ensures a fresh, reliable starting point with zero accumulated wear or fatigue.
33-spline inboard engagement matches OEM specifications precisely, ensuring proper torque transfer and eliminating fitment guesswork on 2019-2021 Ram 3500 DRW applications.
40-3/16 in. inner shaft length is dimensionally accurate to OE, ensuring correct seating depth and eliminating interference during installation.
Double-drilled flange design accommodates multiple wheel and hub configurations, making this shaft well-suited for fleet and commercial DRW service environments.
Rust-resistant coating protects the shaft surface from corrosion during storage and throughout service life — important for heavy-duty trucks operating in harsh or wet conditions.
US Powertrain engineering reviews OEM designs for known weaknesses and applies improvements during manufacturing — going beyond simple replication to deliver a more robust replacement.
Backed by a 90-day warranty, providing documented coverage and purchase confidence for professional installers and fleet operators.
