2wd vs. 4wd rear leaf springs?

[nlped]

Hey All,

Are 4wd Leaf springs and 2wd leaf springs interchangable? I need to get the rear of my '76 up just a couple of inches. I have put the 4wd Tahoe leafs on it, and flipped it, but it is WAY low. Like, the rear receiver hitch is about 2" off the ground, and I tow a boat, so this is too low. So, I was wondering if the 4wd leafs were the same length, eye to eye, and do they have more of an arch?

I gotta get this raised up just a bit...Help!!!
