    For those of you who have been able to compare an all around spring lift versus a shackle reversal, would you share your thoughts please. In particular, a 4 inch lift versus the ORD reversal with stock springs. Thanks.

    Does spring lift mean like blocks or lift springs for the rear? I have blocks. I'm gonna get the shackle flip. Better flex that way than if you went with lift springs and not so much axle wrap as with the blocks (which I'm getting a heck of a lot of with my blocks [​IMG]). I'll be getting the shackle flip soon. [​IMG]

    I've got a mind like a . . . a . . . what's that thing called?

    Yes, I'm referring to a rear spring lift.
    The rear springs on my Jimmy are in good shape.
    I was just wondering how the two rides compare on road?

    I think there are two different schools of thought here. Cost and ease of installation. The springs are more money, but the shackle flip is alot of work. You could also cut the bottom of your existing hanger out and do it for virtually nothing! I did mine a few weeks ago, there was really nothing to it. You can see it on my pickter page. I haven't had any problems and I've twisted it up a little bit. One of these days I'll beef it back up a little. Good luck with your choice.

    I am planning on doing the shackle flip on my blazer also. seems like the way to go. We just finished one on my buddies 1973 chevy 3/4 ton truck and we have been wheelin pretty hard in it and it is working out super. SHAKLE FLIP IS THE WAY TO GO I THINK.

    Hey JimmyJack,

    Did you need to get new brake lines with the flip?

    Because my rear springs were 22 years old and in need of rebuild/de-rusting, so I went with a 4" Tuff Country all spring lift. For a 4" lift a spring lift seems equal to the stock ones with a block IMO. Stephen at ORD seemed to think anything over 4" lift in the rear you should go at least partial shackle flip.

    I'm no expert, but from what I remember reading the reason to do the shackle flip is to stay with a softer "stock" spring.

    If you get a 4" spring lift (no blocks) the spring will have to be stiffer to do the same job. My impression is that the shackle flip preserves the ride quality, but allows you to get the truck to the height you want.

    Well, still undecided. My Jimmy is mostly a daily driver. What I need to do is find someone who has the shackle flip and go for a test ride. I appreciate everyone's input.
    Thanks!

    A shackle flip is when you flip the rear shackle to go from the spring up in sted of down to the pearch. You buy the kit from <a target="_blank" href=http://www.offroaddesign.com/catalog/shacklekit.htm>http://www.offroaddesign.com/catalog/shacklekit.htm</a>or do it your self by cutting out the bottom of the pearch and reinforcing it.

    Those of you with shackle flips, how long did it take you to install it? Leaf springs aren't so easy to install either.

    Go with the Shackle Flip. while you're at it, get greasable bushings. the Flip also moves the pivot point forward which increases articulation, that's why they look "offset". If your concern is sagging rear springs, use an Add-A-Leaf. I noticed no loss in articulation but my ride improved. Currently I'm running a 4" Tuff Country lift with the ORD shackle flip and Add-A-Leafs in the rear. Never been happier!

    Every time I get near my Blazer with my grinder in hand I want to attack those shackles. Guess I better get front springs first, otherwise I'll have a comic book looking ride...

    The only draw back I have noticed with the shackle flip is it makes the shackle more vunerable to rocks. With springs it stays tucked up out of the way.
