I ordered a 85mm piston and the one I got says 82mm.

We do not have forgings for every piston size. We buy, for example, a 82mm forging, which indicates the smallest size that can be made from it. The actual forging is larger and can be cut to several different sizes. The 82mm, for example, will make an 85, 84, 83, or 82mm piston depending on how much material is cut from the outer surface.
