NNBS 4x4 Limiting Straps
Has anyone installed or setup limiting straps on 4x4 NNBS? I have a 10 Silverado CCSB 4x4 turbo ls3. When launching the truck lifts fairly good and a ton of front tire spin. Any feedback or pictures would be awesome. Other ideas are welcome as well.

So I am in the process of making some lower mounts for the GMT900 trucks to use off the shelf coilovers with the heim joint instead of the Tbar, and mine will also work with limiting straps. Its hard to see but between the top and bottom there is a strut that you could mount a strap to. I am not finished with the design, but any feedback is welcome. These are needed to move over the coilover away from the CV to make some more clearance.
If you want just a good limit strap mounting point I could add a loop to the bottom piece so you can keep your stock shock will just need longer bolts.

Certainly looks like a good setup. Is this going to be usable with stock strut by just taking the t-bar out of the strut? A tab with an eyelet or a longer bolt would work perfect.

This is what I have done. See what you guys think. These are 12" straps. Luckily they were perfect but I may switch to an 11" if I want to compress the front but don't see it needed yet. These are setup at the length of where the struts want to sit but cannot extend.
Race Ready > Limit Straps
Before: Boosted 4x4 launch the truck would skate for about 25-30 feet spinning pretty bad. Then hook but would cause my 1-2 shift to be inconsistent because of tire spin. 1-2 shift would have a slight hesitation. Would average about 2.8-3.0 second 0-60.
After: I 4x4 launched it twice immediately after the installation. ZERO wheel spin. Straight line and very smooth. 0-60 time has not been tested yet but I wouldn't be surprised if it touched 2.5-2.7 seconds.
Only other suspension mods are rear drop shackle, rear black removal, and assassin traction bars.

Not bad results but I don't like how they put force on the upper control arm when the suspension tries to extend. Seems like after a while it would fatigue suspension bushings or even rub the strap to the point of failure.
Looks like the fix for you would be to run a smaller OD spring setup and flip the top mount to the inside of that pocket.
