I'm making lift shackles for my ZR2. My stock shackles measure out to 4inches center bolt to center bolt. Now for my under standing is to gain 2 inches of lift the measurement would have to be 8 inches center to center. Can someone please verify this

 

I wanna say my shackles are 6 inches apart on my non ZR2 blazer but that makes sense to me to just add 2 inches. Have you done a search to find help.

 

I have searched and for what I can find is that every inch added with give a half of a inch. Makes since to be because your Not moving both ends just one end down

 

I would guess +2" on stock

your only moving one end however its not straight up and down ???

old school car shackles had multiple holes on the spring end for adjustment

google car shackle images

BTW when you look at online images for blazer ones , look at the proportions ???

 

I have be searching. Maybe I just haven't searched the right thing yet but The closest thing I have found is


Measurement bolt hole to bolt hole = amount of lift

4"= stock
6"= 1" of lift
7"= 1.5" of lift
8"= 2" of lift
9"= 2.5 " of lift
10"= 3" of lift

I don't remember where I found the measurements

 

Yeah since you are only moving one side of the leaf springs, the amount of lift you get is going to be about half, until you get a lot more length than stock.

 

I Got The day off today so I made my shackles today.
I was looking to get 2.5 inches of lift
The measurement of bolt hole to bolt hole is 9 inches apart
Which have me exactly 2.5 inches of lift

 

I didn't realize you were local
You could have made a second set

 

Lol I would if I had The steel. I Just had a few pieces laying around which was just enough to make one set. It was really easy to do. All I had was a grinder and a corded drill.

 

actually I put in a set of air shocks and they run it a little higher than stock
