What metal to use ?

[tc1cat]

It depends upon what you have to make the parts with or if you are going to purchase the parts. Stainless and aluminum both polish up nicely but they have a slightly different color when polished. Aluminum will have a slight blue tint to it when highly polished. Aluminum is easier to machine but will require more maint. after polishing than stainless. Stainless will add more weight to the truck if you are needing more pulling power there is always that to consider also.

Hope this helps.
