Base Model Kenworth HVAC Box
Our base model, is the most universal Kenworth HVAC box that we produce. We currently offer two options of this unit the F31-1036SS-1 and F31-1037SS-1. Our F31-1036SS-1 is for your heavy-duty model trucks such as the W900, T800, T600, and so on. The F31-1037SS-1 is for the medium-duty T270, T300, & T370. 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.
