Hey Zuk Ive got 3" blocks under the rear of my 88 runner but the rear still sets about 2" lower than the front, front has 4" IFS lift. Would the stock hieght application suffice since the top of the spring pack has been lifted by the block? Or even better do you think I could apply the coil setup to allow me to get rid of the blocks altogether?
Yours still has the stock factory worn out leaf packs with the stiff overload leaf? Still have the factory length shackle? If so, then that means you have about the same 8" measurement from leaf to frame as shown in the very first pic of this thread page 1. Yes, the stock application would work for you and lift it between 3 and 4 inches....and that's with the 12" long coils.
In your case, that means if you took the blocks out it might still be a little low BUT with the longer 14" coils... then you would be about right. Longer shackles could add even more height. Blocks suck <img src="/forums/images/graemlins/cheers.gif" alt="" />
EDIT---actually....I just thought of this....could do something like I did for Geriatric....but instead of a 4" spacer under each 12" coil.....make it a 2". And, if for some reason it is too high, then the spacers can be removed with minimal trouble. This would allow you to get rid of the 3" blocks you have now and get a soft ride again.
By the way, a 2 inch spacer under the coil actually effects the lift by about 1" due to the sharing of the lift between the coils and leafs.
