Our F31-1036SS-1 and F31-1288SS-1 are for 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 all new K142-464SS-1 is built for the Kenworth K100E.

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?

21 Point Comparison Chart

“I’ve installed one of your boxes on a customer’s truck. They install nicely and the quality is superb… I wish I found your product before spending 2 days fabricating one for my KW… I’ve installed a couple different aftermarket ones. Yours went the smoothest of any.”

“Just finished an install for my 02′ KW T800. Installed smoothly with a very little issues. Now have strong heat AND A/C. I shouldn’t have hesitated ordering because the quality is definitely there!.”

“Ordering the HVAC box was easy. The staff at Shoreline helped make this job a breeze. The price is fair and the shipping cost was low considering the quick delivery time. Thanks Shoreline. Great product!”
