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 truck 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. We accept all credit cards!

We build our boxes with high-quality 18 gauge 304 stainless steel and use stainless steel fasteners. We spot weld our boxes for extra strength instead of using flimsy aluminum rivets like our competitors.

Includes:

  • Stainless steel box
  • Upgraded blower motor included (15% increase of CFM compared to OEM)
  • Gasket kit
  • Other internal parts not included
