10 leafs doesn't sound right. even the heaviest duty c10's from the factory came with 5 on each side. How rough do you want it to ride?

My '73 4900 GVWR has 7 plus the overload.

The truck is very mix matched, big 10 cab. Stepside bed, duallie rear. Its a c10 4wd... i have heard of helper springs but i havent hesrd of thrm so i dont know what they would look like. I dint plan on running too rough, plowing in the winter this einter, probably not next, and toeing older cars is biut the roughest im going to do, i was thinking 5 would be plenty but wanted to see ehats up

This is incorrect. My old 74swb came w/the HD pkg which was 8-leafs.

Start by measuring your springs (52 or 56" eye to eye following the arc of the main leaf). If you have 56" springs, you probably have 1 ton springs on there, there is a 10 leaf spring pack rated for 4000lbs, and a 5000lb pack.

If you have 52" springs, you may have extreme duty aftermarket springs, I was looking at leaf springs last week and came across a place that sold springs (52" and 56") for tow truck use. They had some massive packs. Of course, now that I need to find it again I can't. OR somebody at one time added a leaf to the 9 leaf pack, not uncommon if you are trying to haul more on the cheap.

7 leaf 2850 lb springs on my C10. Rides like a truck should =-) and doesn't sag when you are hauling something.

Drivers side with the extra leaf? Fat guy owner and/or inbed camper haulers usually have the mixed springs I've noticed.

My '73 1/2 ton has the 56" springs, factory.

One of the nice things about the 73-87, just about every combination under the sun, and then some more.

I've attached the GVWR for 1977 C10's and C30's which will give you some idea of spring packs and ratings. For example, my C30 has 9 leafs per side + the overload. If I'm not mistaken the individual leaves are wider and thicker on the heavier trucks, but I may be wrong. I know the perches between a 12 bolt and a 14 bolt or Dana 70hd are wider, so I assumed the springs were wider as well.

I once owned a 1 ton Jeep J-30 that only has 3 leaves per side; they were each about an inch thick and that thing would pack a load as well as my C30.
