Thats not why I bought my truck, but I like saving 30-40 miles a day so I avoid the freeway and take the canyons to and from work. If a rear sway bar would help with the ride then id be interested in doing it.A rear sway bar will tend to cause oversteer if it is too big/adjusted wrong. That is not good on a tall truck with a high center of gravity. You don't buy these trucks to go throgh a slalom course. If you do your in the wrong vehicle. Get a Camaro.
