I have the springs in your link and am happy with the way they perform. I did have to "clearance" the cast bracket to get them to "fit". These springs DID lower the truck from the "factory stock" height, but did NOT lower the truck, because my front leaf springs were already sagging 2 1/2". Another thing to keep in mind, I think the GM 350 motor is about 50 pounds lighter than the 6 cylinder. Someone will correct me if I am wrong.
