Perpetual Transient
I posted some stuff on "Jacks 2007 Chevy build" in the last couple pages about drilling the u bolt plates to allow drainage and rust prevention and installing an earlier 1988-98 rear overload that has more of a progressive taper to it.
You may have to check your length to see if it fits inside of your main spring leaf clamps, but they are easily shortened with a chop saw. You need a wet rag wrapped around the overload as a heat sink and redrill the wear pad holes. A machine shop can redrill the wear pad holes in the overloads unless you have some super hard bits. If the overload extends past the spring clamps your good.
The earlier overloads are 41 or 42 inches long.
Interesting, I will look at that thread. Thanks for sharing.
