For those of you who with a sagging rear , pun intended , and your suspensions air pump and leveler are still functioning you can carefully remove your frame to air leveler valve ROD and cut it in half , yes it’s metal in the center but plastic on the ends so be careful, take a 10-42 die and thread the ends of the arms of your two pieces as far down as you can go and buy the smallest adjustment sleeve ace hardware has and install it with a locking nut at each each end to lock it up when you get your desired ride height . No this isn’t for the average diyer but hey I’ll try anything once . It takes a while for the pump to kick in so this is fairly time consuming.
