    Great product.

    The latch mount bolted right up with nomproblems. I did order the blemished option. There were a couple spots where the paint bubbled... Hints the blemish price. There was a missing hole for the locating pin that is cast into the plastic grill mount piece, wasn't an issue to drill out. I'm not It sure if that was a part of the blemished deal or not.
    Not complaining, just observing.
    I would absolutely recommend it and buy again if I need to. I haven't installed the cooler yet but, I'm sure it'll go just fine.

    Beautifully made in the USA

    While accumulating parts for my new-to-me ‘94 C3500 dually, I reached out to Kloc Fabrication asking about custom fitting placement to work with the 6.5 hose routing. I got a response the next business day and by coincidence, they were actually in the process of making a direct replacement for the 6.5 trucks. I ordered one as soon as I saw they were available. Received quickly and was very well packaged. High quality aluminum and nice welds. Even came with nice hardware to mount to the firewall. Can’t wait to put it in the truck and retaining the factory low coolant sensor is an added bonus. Much better solution than a used plastic tank or trying to make a tank from a different vehicle work. Will be a great finishing touch to go along with my aluminum radiator, 2000 water pump, Kodiak fan clutch, and 9 blade fan. Always happy to support a small business!

    Looks flawless. Came with new hardwear to replace the rusting bolts. Hand written thank you on the invoice, not some generic copy pasted corprate BS. More companies need to be like Kloc Fabrication.

    First off, the customer service is top-notch, and that is hard to find nowadays. I am still in the process of building my truck, so I have not used these two items yet, but the quality of the parts is excellent. I’m looking forward to ordering more parts in the future. Thanks again, Spencer, for the help!
