T-Case Gear Set. Choosing the right material for our gears was our top priority. Gears that perform well under load and street driving require a high quality steel alloy material. We chose Japanese alloy SCM415 for its great strength and wear resistance.

SCM415 outperforms the 8620 material in yield and ultimate tensile strength resulting in a gear that is less prone to chipping or cracking. SCM415 also retains its strength under high-temperature use.

High carbon materials such as SCM420 or 8620 are not the best choice in our experience and opinion as they do not carburize as well and can become brittle.
