so our (lowered4life and I) k10 when we got it already had a rough country 4" lift and we believe has 1 ton springs. we did some research and found what is below, from pictures (truck is at our shop and its late, didnt want to drive down there) the front has 4 leafs, so according to this info it has 1 ton front springs. so we assume the rear is the same. so, would it be ok for us to remove a leaf or two on the spring packs to soften the ride? or do we need to get the 1/2 ton springs? the way i rear it the leafs are the same rate just more of them. now the rears we need to measure to identify it better but could we do the same? the ride is way too stiff for driving in the dessert. oh and we would make up for the drop by possibly flipping the hanger in the rear and maybe some shackles in the front

Front Leaf Springs
K10, K20, and K30 Use the same springs. Differance is, they come in 2 leaf, 3 leaf or 4 leaf set up. All 3 set ups are interchangeable between all 3 models.
I'd imagine the K30 comes in the 4 leaf set up, but the K10 and K20 could be either the 2 or 3 set up depending on heavy duty RPO code or not.
Rear Leaf Spring 2WD C10, C20, C30.
C10 can be 52 inch or 56 inch springs. Depending on Heavy Duty RPO code.
C20 is 56 inch springs. # of leafs and thickness of spring pack depends on RPO code, ie... Smooth Ride, Heavy Duty etc.
C30 is 56 inch springs. # of leafs and thickness of spring pack depends on on RPO code. 10 Leafs is Heavy Duty 1 ton.
Rear Leaf Springs 4WD K10, K20, K30.
K10 is 52 inch springs. # of leafs and thickness of pack depends on RPO code.
K20 can be 52 inch or 56 inch springs. Depending on Heavy Duty RPO code or not. (Appears that 52 inch may be more common)
K30 is 56 inch springs. # of leafs and thickness of spring pack depends on on RPO code.
