28, 30 and 31 spline alloy axle package

Each Strange forged alloy steel custom axle is manufactured to your exact specifications.

To provide greater flexibility Strange axles are CNC precision machined from premium forged alloy steel then they are induction hardened to resist bending loads. When axles are intended for use in street applications this is very important.

We Cut Before Heat Treatment, Not After.

Strange axles go through an induction hardening process. This specific type of induction hardening is used to treat all Strange alloy steel axles.

This process allows the axles to survive the bending loads associated with street usage. We can not stress enough the importance that Strange Engineering does all of its machine work on the splines prior to heat treatment. This allows for consistent heat treat depth, leading to a stronger axle. Be aware that some companies heat-treat the materials before the splines are machined into the axle, which causes it to be weaker despite the shiny look.

Strange axles are manufactured with a larger than stock axle bearing diameter area (1.563-inch). To minimize stress concentration in the bearing area the Strange axle shoulder is designed to accept a larger radius ring.
