Leaf mount stupid question

[4xKiller]

Alright, I know p/u's have a step up at the back of the cab where the bed starts. On my Toy, the front of the rear leaf is mounted here about half way up the step. If I move those mounts back about 8" (less rear overhang), it would mean that my leaf is now mounted "parallel" to the frame instead of at a slight angle (due to the mounts being at the top of the step). Is this ok??? What would the effects of this be?? I know I'm lifting the front of my truck 5", but how do I calculate the rear lift so I won't be a tail dragger? This is just something I've been thinking about since I don't know jack when it comes to suspension setups. Any help would be appreciated

I'm not 100% sure on what your asking but am guessing your talking about moving the spring mount to a point where it will be mounted higher up in the chassis.

If so to figure out how much lift you will lose by moving the spring mount up it will be half the distance you moved the mount up from its original position. So if you move the spring mount up 3" you will lower the rear of the truck 1.5".

You would probably be better off going to a longer spring with an offset center pin so you can still decrease the rear overhang but keep a flatter spring for better flex (a longer spring will also flex better then a shorter one)

thanks. where do I measure the height difference, center of the spring eye being moved, or just from the mount itself? The reason I'm moving the spring is to reduce rear overhang and ALSO increase wheelbase. It's an 88 Toy regular cab short bed and I'm going to replace the cab w/ an extended and alter the bed to fit.

I would measure from old spring eye to new
