The ones that I ordered are 1650 lbs springs, Im sure they will be a good stock replacement spring. As far as the frame around the hangers its fine, it had to been the quality of steel used in the brackets, all my frame has is light surface rust. My 95 F150 is a regular cab with an 8 foot bed. Im really convinced that it was the quality of steel used for all of these brackets. My 82 F100 which has been a michigan truck since new still has the orginal brackets and they are in great shape. Now the body on the 82 is a different story. I just don't understand how a 1/4 thick piece of steel can rust off in layers and pop holes. Also my dads 92 F150 has the same issue with the brackets. Thanks again, I'll take some pictures of when I do the job in the next few weeks.
