1982 C/30 crew cab 2WD front coil Design Load

[Axle]

A few different rates. For leaf springs, measure the pack thickness to have a good idea of what spring your truck currently has installed as there are multiple springs with the same number of leaves but different weight ratings. And your front springs kinda have to be matched up for a decent ride. If the front is too stiff and the rear is all bouncy makes for a terrible handling truck. The other way around isn't as bad. I think I grabbed the screen shots from trucksprings dot com. I do not have a coil spring list, seems those are all click one to check the specs rather than a concise list.

Attached is rear leaf spring list. P.T. is pack thickness. Measure carefully as an 1/8" makes a difference. And measure it where it is clamped to the axle. This isn't a complete list, or maybe its only whats available anymore over the shelf as I had 7+1 26"+26" spring on my 1/2t with 3 5/8 pack
