Nitro Gear & Axle · AXFF35-33.5

Nitro Gear and Axle now offers an assortment of Heavy Duty Cut-to-Length (CTL) rear axle shafts. The CTL axle shafts feature extra Long splines and can easily be cut to the desired length with a chop saw. This allows Nitro to use stronger rolled splines rather than cut splines and allows fewer part numbers to cover a wide range of OE and custom Fits. This also makes it easier for Offroad, restoration, and Rod Shops to stock axles since they fit so many Fits. Our OE replacement axles are made of 1541H steel for a 25-35 percent increase in strength over their stock counterparts. Nitro 4340 Chromoly axles are also heat treated but are designed with extra material for strength where its needed. All of our axles are precision machined to OE specifications for excellent fitment. 1541H steel is a heat treated, carbon steel with .41 percent or less of other impurities. The heat treatments make the metal harder, with out making it brittle with a tensile strength of 181,000 psi. Up to 35 percent stronger than OE axles. 4340 Chromoly steel, is a lower carbon steel with a minimum of 10 percent chromium by weight.
