38 1.5 ton Built a heavy duty 4 link for my 51 6400,had no idea what it would like,got coil springs from speedy Bill in nebraska 5x13. It bottomed out at times,got 5x15 opened it up like clambshell with the winch truck,dropped them in fixed it !! Used just over the counter Monroe shocks with enough travel it couldn't bottom out. Now on a hard stop will rock and dampen right out. Thinking about putting shocks on the front,saw that spring leaves are digging into the leaf above a little might need to carefully grind those back a little. Have driven it about 10,000 miles since 2018 funnest pick-up out of about 30 i've had in 50 years.
