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!”
