Thanks to all who commented on this thread, as always you never have too much information to make an informed decision.....I went ahead and had the 3300lb. rated spring installed today and it fit perfectly and the truck sits level with no load, the only exception was I had to use my old top 'helper spring so they had to replace the center bolt to get the block between the main spring and the helper re-bolted into one unit. I'll let everyone know if after I load the body the other spring sags and if I will end up replacing that side too. As of now I don't see that happening. I'll also add again that if you live out in the sticks like I do and need springs General Spring in Kansas city are very reasonable and the service is simply the best bar none.
