Leaf spring lengths?

[CG]

So Ive been looking at leafs for my 4x4, I figured all of our trucks had the same length front and rear. I don't know about Blazers though so they might be different.

Ive been getting ideas for my K-GMC and I see several spring manufacturers are listing the Burbs separately (they have their own page). Is this a thing, or are they trying to make sure everyone is included and all of our 4x4 trucks actually have same springs?

Mark,
All 67-72 4X4's have the same length springs, but 67-68 springs were tapered at the ends making the perches and shackles wider, All 69-72 springs were the same width, The only differences being if a truck had the optional heavy duty front springs with more leafs and of course the leaf count differences in the rear between 1/2 ton 3/4 ton.
