In my words
Axle PRO-MT 4X4 is bench hardware: dull on the shelf, loud on the track.
Hardware is the part of the car you only upgrade once, which makes the first choice worth the thought.
Sizes and colors come and go on this one; the listing shows what is actually in the box today.
What Pro-Line says about it
- Includes a Replacement PRO-MT 4x4 Axle
- Made from Black Oxide Coated Hardened Steel
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.
