Front spring differnces?

[Parkerkl]

I am looking to purchase a set of stock height front springs for a my 70 3/4 ton 4x4. I have found sets at a couple of sites but they say they are the same for k10 and k20, both 2 and 3 leaf set ups. Am I missing something? I thought K20 leafs were beefier. Any clarification would be helpful.
thanks

The 69-72 OEM front springs were the same for K10 and K20, 2 leaf standard and 3 leaf heavy duty.

Chevrolet Part #
69-71 K10 and K20 standard 2 leaves #328790, heavy duty 3 leaves #328792

72 K10 and K20 standard 2 leaves #328795, heavy duty 3 leaves #328796

for all practical pourposes, the front springs aren't holding much more weight in a loaded 10 series verses a loaded 20 series.

So, engine size and weight have no effect on the front spring height? I always thought that front springs were rated by engine size as well as vehicle weight to achive the same stock ride height.

There may not be much difference between the weight of an I6 and a sbc -- and the heavier bbc was not available in a 4x4.

there is that, plus the fact that all measurements were plus or minus x% or x inches.
So to say the bumper was 10 inches off the ground.... +/- 1.5 inches... the same spring could do the job.

Could I use the 72 springs on my 70? I have a line on a set.
