Bamboo, I didn't weigh all the parts taken off and parts added but once you remove the fan and all attaching hardware for the rad it is a wash as far as the weight goes. The weight is better located to the rear of the sled.
I pulled my radiator, fan, and a few brackets I should have weighed them. It is nice I can actually get to my coils the hood is so much cleaner. It runs extremely cool it has never been over 145 either the supercharger oil or water temp, amazing.
