The problem with the OEM Kenworth heater box assembly is that it is made of steel and easily rusts due to the salty, wet conditions that your rig experiences on a regular basis. What’s the solution? The solution is to use a far superior design made from stainless steel. Our heater boxes will never rust! Get yours today! Call now at (616) 834-1503 or click Add to Cart.
