Why do you need Alloy USA axle shafts? Because horsepower is useless if you can't get it to the ground. Alloy USA performance rear axle shafts feature 1541H alloy steel and have been propelling cars to victory for nearly a decade. 1541H is a high carbon steel that contains significantly more maganese than 1040 steel found in stock axles. This increases ductility and translates the ability to absorb stresses.

Alloy USA heat-treated and induction hardened shafts have twice the tensile strength than stock and are up to 35% stronger. Each shaft is created using the latest cold spline rolling technology to produce splines that are stronger than traditional cut splines. No cuts means no edges, which create stress oints and can lead to fracturing. All axle shafts are precision CNC machined and magnaflux inspected for cracks before receiving a slick black anodized or natural finish. Each kit includes driver and passenger side axle shafts, seals, bearings, and wheel studs.
