    custom mustang catch can, awesome

    spencer from Kloc fabrication was awesome, he was able to take my vision for an oil catch can, custom made by an idea I had in my head, and it came out better than I hoped for it looks phenomenal, and it fits in the location like it was a factory option, it was also shipped with great care, packaged very well, and arrived quick, I will definitely be using them again for any future projects, thanks Brian

    Beautiful addition under the hood.

    Easier to install than the original plastic reservoir, and functions perfectly. Great way to start making the truck look as good under the hood as it does on the outside.

    Purchased the coolant overflow tank and the washer fluid tank. The engineering and fabrication is spot on. Direct bolt on fit for original replacement. Definitely worth the price. Dressed up the engine bay perfectly. I would buy again and Definitely recommend.

    Quality parts

    If you’re looking for the best aftermarket oil cooler lines look no further. These braided lines are unmatched quality and 100% worth the upgrade from the fault-prone OEM style lines. I received a package packed with care and included very useful and in-depth instructions that made installation easy.

    Extremely Satisfied

    I had a great experience. From conversations inquiring about product availability to getting my questions answered quickly and my product delivered promptly, I am very happy. The product was exactly as described. Mild blemishes (knowingly purchased blemished product with intention to pain) but overall structural assembly and appearance of welds was top notch. Would have no hesitation buying or doing business again.

    Excellent value, transparency and shipping speed!

    Found Kloc Fabrication when looking for a genuine Tru Cool 40k transmission cooler. Could not find a trustworthy option on EBay, Amazon or general online search until I found Kloc. Shipping was free and speed was fantastic! They offer a genuine Dana Tru Cool replacement from an authorized supplier. Way better than the deceitful junk sold on EBay. Very pleased with the transparency and service provided and love to support small family businesses whenever possible. Highly recommend Kloc Fabrication for your custom automotive needs!

    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.
