Features and Benefits
Newly manufactured steel axle shaft — not remanufactured or recycled — ensures consistent metallurgical quality and eliminates the hidden fatigue common in salvage-yard or rebuilt alternatives.
30 inboard splines and 31-9/32 in. inner shaft length match OE dimensions precisely, delivering a direct, no-modification fit in 1970-1981 GM C/K 10 and 1500 rear axle housings.
Rust-resistant coating protects the shaft surface from corrosion during storage, shipping, and in-service use — critical for trucks and SUVs frequently exposed to road salt or off-road moisture.
Manufactured in the USA by US Powertrain, a dedicated drivetrain specialist that evaluates OEM design flaws and incorporates engineering improvements beyond the original specification.
Covers a wide classic GM application range — 1970-1981 Chevrolet Blazer, C10 Pickup, K10 Pickup and 1970-1981 GMC Jimmy, C1500, C1500 Suburban, K1500, K1500 Suburban — from a single part number.
Backed by a 1-year parts warranty, providing confidence in quality and long-term drivetrain reliability for your classic truck restoration or repair.
