Welcome to MAR-K’S Plant Tour!

MAR-K manufactures precision sheet metal replacement body and trim parts for the automotive aftermarket. Products are typically roll formed, press formed, welded, or machined parts in steel, stainless steel, aluminum, or plastic. Our product line includes thousands of replacement parts for older cars and pickup trucks, including pickup bed parts, body moldings, battery trays, hardware items, and custom parts. Over 125 dealers in the United States and Canada proudly sell American made Mar-K products, which are acclaimed to be the best quality in the industry.

At MAR-K we build our parts for owners and builders who recognize the importance of buying parts which are precision made for accurate fit and long term durability.  Our customers understand that a poor quality part ends up being more expensive than one which is made right, especially when costs of installation, modification for proper fit and appearance of the finished job are considered.
