Kert's shackle flip

[78Suburban]

How much more lift would I get if I went with 6" shackles instead or the regular size? I'm thinking I would end up with 4 3/4" lift out back, right? Would the longer shackle make my pinion point even farther up? I'm worried it might actually end up being pointed too far up, because I'm putting it on a burb, which has a longer driveshaft than a blazer, hence less of a need for pinion angle corrections when lifting.

I have 4" RC springs and zero rates for the front. Is it possible I can use the flip with 6" shackles and not have a saggy butt? I would rather not have to take the u bolts off and fool with a rear lift block or zero rate, if I can help it.

thanks,
James

However much longer the shackle is from stock will raise the truck half that distance.

Ok, i have his shackle flip(4"), his 6" shackle...and a zero rate(1") And i sit slightly higher in the rear than my front 6" leafs. It will give you right about 5" of lift.

Absolutely awsome, that's exactly what I was wanting to hear.

What's your pinion angle like?

My angle with stock perches on my 10b is slightly lower than pointing right at the tcase. It might be a lil high for you being a burban, but nothing some small shims run backwards cant fix imo.

I think you should run it how it is. and see how it looks, and if you need shims, then order some.
