Derale 13315 Series 7000 Tube and Fin Cooler Core,Black

Using this to cool my 4L80 on a 2500HD plow truck. Definitely dropped temperatures compared to the stock HD cooling system.

Excellent packaging, very good fit and finish for the price. There is a thick, vacuum-sealed covering to protect the fins in the package. The black coating is very uniform. The only flaws were some edging blemishes around the fittings, which is perfectly reasonable. Short of a concourse build, this should satisfy any project.

a hoax, the measurements are incorrect and different from what is specified, the product is much smaller

Cooler is large and works great.

wrong dimensions

Disappointed! As far as the build quality, it’s what I was expecting. Lightweight with AN fittings, it’s what I was looking for. HOWEVER, the product description states that the dimensions are roughly 17”x24”. Not the case. It measures roughly 13”x17” Unfortunately, I need it this weekend and don’t have time to return. There are others out there for less for the same size.

I built an aftercooler for my air compressor and used this product to cool the compressed air before it reaches the tank. I mounted a small fan that blows air thru the fins. The lines coming into it are hot and the lines coming out are room temperature. I am pleased with the result.
