Ok, so I bought pieces of a hand me down kit from a buddy of mine that included some rear greasable shackles. He didn't know how much of a lift they added or brand, but thinks they were rubicon express. So my question is this: is there a way of measuring the shackle to see how much lift it would add? or comparing it to a stock length?



Any help would be appreciated!

 

What is the distance from center of eye to eye?

 

I think you get about 1/2 the difference of the old shackle length and the new shackle length.
If your stock shackle is 3 1/2' bolt hole to bolt hole. And new shackle is 7 1/2". you get a 2" lift.

 

That was my logic ain trying to ask the length.

 

Are they the Boomerang Shackles? The greaseable shackles do help the rear springs with a little more flex but you must keep them greased, often!

 

They aren't boomerang shackles, just greasable :/

The over all length of them is 8 inches, but from the actual eye to eye is roughly 6.5 inches

Im gonna try and get some pics up today..

 

Seems like that would get you about 1 1/2' lift

Ok, so this is what I have:

Thanks for all of the replies

 

Okay? Those pictures just confused me. In one it looks like they are 8 total and in one it looks 8" eye to eye.

 

I think it's just the angle of the first picture. Remmeber that they might give you more than half of the extra length if your shackle angle isn't 45 degrees.
