Lift on composite leaf springs?

It looks possible to put a block between the axle and the plate under the mono leaf. Just need to size the u bolts. They seam to be 9/16" but it's measuring 3 3/8" between which is not a common width.

Wonder if it’s a taper block or if I could just use the one that comes with a 6 inch lift kit? Anyone try it on a mono leaf?

Anyone see rear block lifts available yet for this new single leaf set up?

Has anyone found a solution to this yet?

Would like to go with a block.

Also will the TB/AT4 leaf springs bolt right up to the shackles on these?

I'm just going to drop these right here because I think they might help somebody. Find them about 2 weeks ago while playing on ReadyLift's website. I remembered them while reading this thread.

You can keep your leafs. There’s a few kits now. Rough country also sells rounded ubolts at 3.25” wide which fit perfect. There’s a 1/4” plate under the leaf that’s 3” wide to give the leafs full bearing for the axle. Keep that. Put a block under it. RC nylon blocks seem to fit well. Yes I know you shouldn’t stack blocks but I’m not considering that plate a block. It has lips and groves to hold it in place. Without it, the blocks are only 2.5” wide which I’m sure isn’t good for the leaf. Do at your own risk.
