Titanium driveshaft, impeller housing or stator vane assembly

A material rule, not a part rule. Explicitly banned in several classes.


Where it stands, class by class

20 classes, grouped by the answer rather than listed one by one, because an answer that holds for a class usually holds for every class that borrows its rules.

Not permitted, not listed in the rules Our reading, not a rule we can quote at you. This class requires the craft to stay stock except where the rules allow otherwise, and this part is not on the list.

Not legal 1 class

Titanium driveshafts prohibited.

  • Sport Spec · none - this document uses ALL-CAPS section headings, not numbered rules

The rules do not say 1 class

No titanium prohibition stated, but no permission either. Titanium FASTENERS are prohibited unless originally equipped.

Legal 1 class

Titanium driveshaft, impeller housing or stator vane assemblies ARE permitted in Vintage Ski. This is the opposite of X2 and SC and worth verifying.


Titanium driveshaft, impeller housing or stator vane assembly: if the rule your class applies reads differently to you, or the rulebook has changed since this was read, ask. We answer with the section we read it from, or that we have not read it. Ask a rules question.
