Hi Marty, I appreciate all the information on the suspension re-work you did on your 2015 Silverado 2wd, and I'll run the article by the 4wheel drive shop I visited earlier who said there was really nothing he could think of that would remedy the issues on newer 4x4's, mine is a 2017 with a max towing package ( I ordered after getting bad information on it's ride characteristics) and he hadn't heard of anyone who has tackled the issue, and I don't know how similar my 2017 4x4 suspension is to the suspension on your 2015 two wheel drive Silverado. But it's worth looking into, so thanks again.
