Custom Axles

With an approximate 2-day turnaround time, each Strange forged alloy steel custom axle is manufactured to your exact specifications.

To provide greater flexibility, Strange alloy axles are CNC precision machined from premium forged alloy steel and are induction hardened to resist bending loads. When axles are intended for use in street applications, this type of heat treat is crucial to ensure a strong axle that can be safely utilized in this environment.

We Cut Before Heat Treatment, Not After.

We can not stress enough the importance that Strange Engineering does all of its machine work on the axle splines prior to heat treatment. This allows for consistent heat treat depth, leading to a stronger axle. Be aware that many companies heat-treat the materials before the splines are machined into the axle which causes them to have a shiny appearance.

Strange axles are manufactured with a large bearing area diameter (1.563-inch) for additional strength. To minimize stress concentration, the Strange axle shoulder is designed with an extra large radius and utilizes a adaptive ring. As one side mates to the large radius, the other provides a positive stop for the axle bearing.
