Well now, what do we have here? These special axle nuts are actually hardened steel and have a built-in re-threading feature which means your axles won’t strip while using. These come standard on all AF1 models, but you can upgrade your Classics by grabbing 1, 2, or make it a full setup with 4 (enough for 2 trucks). If you haven't yet set up your Ace trucks, these will also work on all other trucks out there.
Sold by the piece. 1 unit is 1 axle nut.
