Features and Benefits
Newly manufactured steel axle shaft — not remanufactured or rebuilt — ensuring consistent metallurgy, precise dimensions, and full structural integrity from the first mile.
Direct-fit design with 31 inboard splines and 37.25-in shaft length matched to factory specifications for the 2020–2025 Silverado/Sierra 2500 HD and 3500 HD SRW drivetrain.
High-strength steel construction withstands the torque loads, towing stress, and payload demands these GM HD trucks are rated to handle — day in and day out.
Rust-resistant coating applied to the shaft exterior extends service life by protecting against corrosion in the harsh underbody environment of a heavy-duty work truck.
8-bolt wheel bolt pattern compatibility confirmed for proper hub integration on applicable SRW Silverado 2500/3500 HD and Sierra 2500/3500 HD configurations.
Backed by a 90-day warranty, providing confidence in product quality for professional technicians and shop owners performing heavy-duty drivetrain repairs.
