ALLOY USA PERFORMANCE REAR AXLE
- High tensile strength Chromoly is heat-treated twice and induction hardened to produce these heavy-duty axles that are up to 35% stronger than stock 1040 axles
- Don’t just replace your axle shafts, upgrade them. For less than the cost or an original replacement axle shaft you can upgrade to an Alloy USA™ performance shaft.
Alloy USA axles are made from 1541H, 4140, or 4340 steel depending on the application. Each axle is double heat-treated and induction hardened to have twice the tensile strength than stock and is up to 35% stronger. Constructed with 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. Alloy USA shafts are covered by an exclusive 10-year warranty!
Axle Shafts Sold Individually. Wheel bearings, seals and wheel studs available separately
