i have talked to chevyman23 on sss.com and he has the same wheels and he says the rub the sway bar on full turn to the left. he has the same truck as me and he says its no problem. but i dont know what will happen when i bring eveything 2 inches lower? like how much will everything change and then what will rub? i might just wait to get 275/50/20 or even 45/20's
