In my words
6x30 to 12mm Hex Adapters Nrw&Wde for 6x30 Wheels is the kind of Monster Truck part you only notice when it is missing.
and the wheels take a 12mm hex. Aluminum is stiff and plastic is forgiving — on a rough track the forgiving part wins.
Sizes and colors come and go on this one; the listing shows what is actually in the box today.

Questions I get about this set
Aluminum or plastic?
Aluminum holds geometry and transfers the hit; plastic bends and comes back. On a rough outdoor track I take plastic in the front and aluminum in the back.
Do I need special tools?
A hex driver set that actually fits, thread-lock and a bench. Rounded hardware costs more time than any part on this page.
