I have it installed -- that kit is marketed to address two problems -- lean and contact. I purchased it for the rear -- it prevents the trackbar from contacting the left kdss/sway bar mount. I also didn't want the kdss shock to be over extended from full droop in the left rear corner when using MT control arms (now it's limited by the fcp shock -- cheaper fix if necessary). Fixed both kdss issues for me. I didn't install the front piece. It pushed the front sway down far enough to lightly contact my rci skid while flexing. I could have trimmed the skid, but didn't bother. I did have slight lean, about 3/4 inch to the right. I believe the kit is more for folks with more common lean to the left, and more than 3/4". I just adjusted my rt fcp shock to even it out, seems to be fine now. And I think they mentioned it had only been tested for lifted vehicles, not stock lean. My kdss was leaning before my lift, and leaning the same amount after my lift -- I fixed it w/ slight adjustment to the shock. I wanted the kit to help w/ the situation in the rear, and it works awesome for me -- excellent fit, includes the needed extended bolts, shipped fast, no regrets. I think others on FB who have used it have reported success. I haven't seen any complaints. Anyone with kdss and modified rear lower links would benefit from this kit.
