When you put a lot of horsepower to big wheels and tires, your stock axles can turn out to be the weak link in your drivetrain, bending, breaking, even twisting the splines. Do it while 4 wheeling off-road and you can end up stranded. Don't risk breaking down out in the sticks when you can upgrade your stock axles for less than the cost of original replacement parts.
These Alloy USA performance axles are made of tough 1541H or 4140 steel, heat treated twice and induction hardened. These heavy-duty axles are made to be twice the tensile strength and 35% stronger than stock 1040 axles. Alloy USA also uses the latest cold spline rolling technology to product splines that are significantly stronger than traditional cut splines. No cuts means no edges, which can create stress points and lead to fracturing.
