[i]I know it is probably too soon to get a new factory head for these new 2.5's from Traxxs. Is there any aftermarket heads to use as a replacement here?[/B]
These seem to come highly recommended. They're called mini fridge. Just click on the traxxass 2.5 link and it'll show you the product and pricing.
