Base Model Kenworth HVAC Box

Our base model, is the most universal Kenworth HVAC box that we produce. Our F31-1036SS-1 and F31-1288ss-1 are for your heavy-duty model trucks such as the T660, W900, T800, T600, and so on. The difference between these two part numbers are the expansion valve brackets. Our base model could be considered our economical option as it comes with less parts than our standard and premium models. Our base model would be great for an individual who plans to reuse many of their own parts and is ok with using  a little bit more elbow grease. Still have questions? Give us a call at (616) 834-1503.

This model includes:

  • Stainless Steel Shell
  • Upgraded Blower Motor
  • Gasket Set
