This is the best quality replacement radiator I could find at the best price!
This is the Original Equipment perfect match part for a 2014-2019 Silverado 1500 with a 5.3-litre engine. I called GM parts online and confirmed it was the right radiator for my 2019 Silverado 1500 LD LT 5.3-liter before purchasing and it worked perfectly and is still working great now after a few weeks in use. The job itself is quite a bit of work. It is about a 5-6 hour job depending on your experience level. The Amazon price was the best I could find for this radiator and since it is an OEM part, it fit perfectly. I looked at other radiators and did not find any that did not have several negative reviews about fitment issues. So to me it was worth paying a little more rather than getting a cheap knock off. I had a hard time even finding a house brand radiator in my area and the one store that had this one had it priced way higher making the Amazon price a great value! My truck runs at the perfect temperature now just like when it was new and no more leaks.

OEM quality
OEM fit and finish, and much cheaper than the dealer. Used this for my 2017 Yukon XL. These trucks are easy to R and R the radiator, it's only about a two hour job with basic tools.
