We put a huge amount of attention into the machining and quality control, especially where it matters most.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003esplines are machined to extremely tight tolerances\u003c\/strong\u003e and are checked carefully to make sure everything fits and engages properly. The shaft is also \u003cstrong\u003enitrided for surface hardening\u003c\/strong\u003e, giving it a hard, wear-resistant surface while maintaining the strength of the 300M material underneath.\u003c\/p\u003e\n\u003cp\u003eThis wasn't an overnight project.
