I used 4” blocks from ProForm Fabrication (they’re also tapered to get the pinion angle straight too).
I didn’t want the *** end to sit up super duper high so to compensate for the thicker pack I used slightly shorter blocks (my oem blocks are 4.5” tall). Old leaf pack is 2” thick and the new ones are 3-9/16“.
The bolt by the fuel tank is not really an issue. Just cut it off flush with the hanger and you can drive it all the way in without hitting the tank. You can fish it out with a magnet and then put the new bolt in from the outside.
I used locally made 5/8” ubolts and my old Barnes4wd top plates to keep the flip. For the eyelets I used 5/8”x 5” fine thread bolts with stover nuts. Removed the old bump stops since they do nothing now.
My truck is a 2001, so it’s time for new springs. I can’t use airbags because unless it’s the c&c kit my gooseneck hitch interferes with the mounting plates. Also the c&c kit sits on the oem block pedestals and I don’t have those anymore now.
It’s time to “spring” into action!
