Nitro 1541H steel and 4340 alloy & chromium and molybdenum alloy axles commonly

known as "chromoly":


Our OE replacement axles are made of 1541H steel for a 25-35% increase in strength over their stock counterparts. Nitro 4340 chromoly axles are also heat treated but are designed with extra material for strength where it's needed. All of our axles are precision machined to OE specifications for excellent fitment.


1541H steel is a heat treated, carbon steel with .41% 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 30% stronger than OE axles.


4340 cromoly steel, is a lower carbon steel with a minimum of 10% chromium by

weight. Known as a high strength, low carbon steel with a tensile strength of

228,000 psi opposed to OE 1040 steel with a tensile strength of 110,000 to

130,000 psi.


That means they take more punishment, to get you further down the trail or off

the trail entirely. That's Nitro Tough.

*Many products will require the use of a direct shipping quote from one of our CSR agents due to new DIM weights and measure changes as of Jan 10th, 2018 from major carriers.

Packages greater than a square cubic foot are now required to use a “volumetric weight” based upon length, width, height of a package from most carriers which alters actual weights. Oversized / Unique shaped packages are most affected and may not apply to your specific purchase(s). However, IN ORDER to save you, the customer, shipping costs, associated fees, and to keep product costs down, we are taking action to give direct shipping quotes based upon delivery methods available. Your full name and email address, required in the checkout, is so we can offer you a shipping quote. Your item(s) will NOT ship without communication from our CSR agents. We apologize for any inconveniences.*
