1541H
UP to 35 percent stronger than OE
CNC machined
Twice the tensile strength over OE
Limited 10 Year Warranty
Don’t just replace your axle shafts, upgrade them. For less than the cost of an original replacement axle shaft you can upgrade to an USA performance shaft. Our axles are made from 1541H. Each axle is heat-treated and induction hardened to have twice the tensile strength than stock and is up to 35 percent stronger. We use the latest cold spline rolling technology to produce splines that are stronger than traditional cut splines. No cuts means no edges which create stress points and can lead to fracturing. Each shaft is backed by our exclusive 10-year warranty.
