Difference between 1/2 ton or 3/4 ton rear springs
This one is puzzling me....
I have a 1984 3/4 ton Chevy 4x4. Stock it had an 8-lug 14 bolt SF rear axle but I installed a 14 bolt FF in its place. My truck has 7-leaf rear springs.
The donor truck that I got the 14 bolt FF from was a `79 Chevy 3/4 ton. It had 9-leaf rear springs. I saved the springs, as they were in good condition. Now, here's the rub - I parted out a 1/2 ton Chevy 2WD (5 lug wheels) a couple of years ago that I also saved the rear springs from -- and they are of the 7-leaf variety. I thought they had fewer leafs, but noticed they were 7-leaf last night when I was moving some parts around.
Does my `84 3/4 ton have 1/2 ton rear springs in it or is the spring constant of the springs in the `84 higher (ie stiffer springs) to make them 3/4 ton springs???
Thanks for any insight.
