In my words
17mm Wheel Hex Set PRO-MT 4X4 is a parts-bin item, which is exactly why I keep it in the pit box.
and the wheels take a 17mm hex. A part that loosens under vibration is a part that fails at the worst moment, so thread-lock everything.
I link straight to the listing so the price you see is the price it sells for today.
What Pro-Line says about it
- Includes Replacement 17mm Wheel Hexes and Hardware
- Wheel Hexes made from Gun Metal Anodized Aluminum
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.
