Super fast shipping less then 24 hrs from the time placed my order.great customer service when I called no answer. But the called back very promptly. The charge air looks well made a little heavier then the garrett but at a fraction of the cost and a decent warranty. Thanks I'm sure I will be using superior for my radiator needs when the time comes. Thanks again superior cooling
Found a replacement radiator for my Ford backhoe on their website. Awesome price and they guaranteed it not to leak. UPS delivered it the next day! I took it from the box and discovered it had a small puncture that appeared to have happened during shipping. I took pictures and called them. After a very short visit by phone, they shipped a replacement next day and said UPS would pick up the damaged one in a few days. Great customer service experience! Will definitely call them again.
The radiator for my American Tradition SE deteriorated and the replacement I got came from Superior and it was. It was all copper and brass ends and bolted together, not like the original thin copper core and plastic ends. OH did I mention 1/3 the price. Doesn't get any better than that and the truck brought it to my door in 5 days. Faster than Spartan's 10 days est. Will come back if I ever need anything they carry.
