Stumpy, first off the truck looks great so far.
The clamping of the front segments works good and I even went as far as making traction bars that welded to the bottom of the spring plates. Eliminated the wheel hop but those are band-aid fixes for worn springs and bushings.
I eventually upgraded to new 3/4 ton springs and didn't need any of it. Stock LRE springs are by the numbers 3/4 ton springs with 1/2 ton hardware.
Lastly, throw away those air shocks. What shocks did you run on the old truck?
