Axle Shims: 4" Shackle Flip 1" Zero Rate AAL

[99'Subourbon]

Hey everyone,

I know this is a reach, but, does anyone have experience with the 4" ORD shackle flips, and 1" Zero Rate AAL?

I'm using those to lift the rear of my truck, instead of the 4" tapered block. I'm wondering what degree shims I should guess to order.
I know it's a long shot, any help is appreciated.

If I were you, I would install the kit and then measure your angles and order the shims you need. Or ask ORD what they recommend and possibly order a couple different sizes and return what you dont need if you need the truck up and running. I drove around for a few days with my pinion angle off a few degrees and everything was fine.

Sorry if this is a dumb question (still learnin' this chit), but how do you go about measuring pinion/axle angles?

I'm wondering the same thing. I Have the ORD 4" Shackles and a Procomp 6" waiting to be installed and i just forgot about these.

you will get 5.5" the rough country tapered blocks are 4 degrees, my truck has no vibrations and its got the 4" and a 2" add a leaf. however when you lower the end of the leaf the leaf surface flattens out so you might not need a 4 degree shim
