Rivals ones at 3x the price
When I looked at pricing on radiators, there was no way I was paying nearly $900 for the top name brand. This radiator appears to be well built, fit perfectly, and is keeping my truck 10-15 degrees cooler than before. It is also a 4 row one, with solid polished aluminum tanks.... looks good, and should not seem fail like the plastic tank one (an expensive name brand one did) after only 4 years.

Didn't last a year and started leaking
Nice radiator but did not last a year so to me it is junk

Quality upgrade.
This is the third F-550 we have upgraded with this radiator. Photo with Flex-O-Lite electric fan assembly.

Leaks at bottom seal!!!
When I opened the box I was happy… Then I had it installed… Leaks at the bottom seal. Just paid to have it put in now I’m going to pay to take it out and buy a new radiator that doesn’t leak.

Junk
I got a pinhole leak in one of the fins, I practiced several time on my OEM rad, pretty easy to fix with a map torch and a aluminum Flux rod...when I tried to fix this rad the aluminum of the Rad which is supposed to melt at 1218* melted before the Flux rod which melts at 700*...this rad must be made from recycled pop cans because even holding the torch to the OEM rad for a few minutes I couldn't get the aluminum to melt...i ordered a misimoto that's made in the US!

Fit ok in 2006 f350
Had to trim the fan shroud at the bottom to fit the extra row. But really can’t tell any cooling temperature difference. Looks cool though

Would not recommend
I’m here writing this review a year after purchase. This radiator did not hold up long term. Very disappointing considering it was more “top of the line” than the others.
