Nitro aftermarket premium axles are some of the strongest in the industry. Adding as much as 40% more strength to the axle shaft.

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 35% stronger than OE axles.

4340 chromoly 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 standard 1040 steel with a tensile strength of 110,000 to 130,000 psi.

Toyota Trucks & Land Cruisers are well known for their strength & reliability all over the world. Out of the box they feature some pretty great drive-train, but they do have their limits. The factory 30 Spline full-floater axle shafts are not built to withstand the added stress of larger tires and heavy off-road use. Nitro Gear & Axle has addressed this by offering a range of Heavy Duty Chromoly Rear Full Float Axles. The only Full Float rear-ends offered by Toyota in the US were in Dually Pickups, and FZJ80 Land Cruiser, however Full float axles were much more popular worldwide in all models of Land Cruisers and are commonly used as an upgrade for US models and otherwise.

Nitro Gear & Axle strives to provide the highest quality differential & axle components available. We take the steps necessary to ensure our parts are dependable.
