Got my 14 bolt underneath the blazer yesterday. I’m running 56” springs in the rear and using an ORD shackle flip kit. In my laziness I tried mounting the brackets backwards to see how the shackle angle looked vs drilling new holes. By flipping the brackets side to side i figured its not that far off from moving them back 4” on the correct side. I know there’s many variables that go into shackle angle just wondering what anyone’s thoughts were on this.

I’m no suspension expert but it looks ok to me. I’m running 56’s w/ ORD 2.5” shackle flips (swap sides like you) and my shackle angle is similar. My set up hasn’t shown any issues and works well.

So now when the spring compresses the shackle moves forward. In doing so, it's gonna lift the truck because of the pivot point location. Will it matter? Not if you don't know any better.

Looks pretty good to me. That angle is about what I would shoot for personally.

Also, swapping them side to side ain't lazy... it's simply doing things the right way :)

Say what now?

When the spring compresses, it will move the shackle to a more horizontal position, not vertical.

Lol. I was just looking at the photos again and I agree because of the springs arch. I went thru something similar on my D60 on the front but it had flat springs and bends the other way. My bad.
