I just installed a rear shackle flip kit and now my shackle angle is terrible

I know I could drill new holes in the frame to move the new hanger forward but are their any other ways to fix the straight up and down angle to get it more towards 45 degrees?

What shackle bracket is that? Also, depending on the angle of your springs, you may simply need a shorter shackle.

Is that bracket from a lowering kit?

It's from Djm, don't think a shorter shackle would help probably make it worse. Called them up and this is the bracket they provided me

A shorter shackle would make it better, but it still wont be good... I say bite the bullet and move the shackle hangers forward, I had to do the same thing on the seal. I dont remember how much I moved them but, if you search my build thread it may be in there.


7" shackles

DJM makes lowering kits right? That looks like the bracket you would use for an spring under axle set-up. Did you look at any of brackets offered by offroaddesign.com, diy4x.com, or the like?

Also, a shorter shackle will help IF the rear eye of your springs is below level.

What about using a longer leaf spring? Chevys are 63 any other stock trucks have a longer leaf spring?

How about a set of these to fit the shackle angle..? If needed you could drill the hole size to whats needed. Jeeps use these alot, look up boomerang shackles on google and you can get a good look at them.. They can be had much much cheaper without the bolts, bushings etc.
those were another option but I couldn't find any that fit the chevy type of hanger how it is tapered down.

These WILL NOT fix a shackle angle. The angle between the shackle bushing centers will not change with the "boomerang" shackle. This is a horrible suggestion.

Thank you!!!

honestly stop trying to magic weight loss pill this situation... just take an afternoon and re-drill 8 holes in your frame and live your life with a correct geometry, smooth riding rear suspension :chair:

I ended up moving the hanger forward and drilling new holes in the frame. My new angle is much better but I lost about 1 inch of lift. The longest shackle I could find was a 7 inch but that only gets me half an inch of lift. Any places make a 8 inch shackle?

That is WAY too long of a shackle. If you need more lift, you need to look at an add-a-leaf, block, or lift springs.

There are things to consider when doing a shackle flip, and using a long shackle along with flip brackets can cause lateral stability issues, change your instant-center, and make body roll more pronounced.

If it were me, I would have used a stock length shackle with a bracket that was meant for a lifted application. Buuuuut, if all he needs is an inch, a zero-rate or EZ inch is all he needs.

BTW, OP, to get 1" lift from the shackle, the shackle needs to be 2" longer or more depending on the angle.
