UPPER: Made from Stainless steel. The part of the mudflap that bolts to your truck. Hence the “Upper” most part of the mudflap assembly.

LOWER: Made from rubber, plastic, or acrylic. The physical “mudflap” part of the mudflap assembly. The “lower” bolts on to the “upper” using 7-8 stainless screws depending on size. The lower is what the weight plate bolts on to.

WEIGHT PLATE: Made from Stainless Steel. Bolts onto the “lower” and comes in custom or standard designs. The weight plate comes in multiple designs shown on the website. Bolts onto the lower and is the final part of the mudflap assembly.
