I'm sure they would work on certain terrain or asphalt, IMO, lower your shocks to a lower setting. my friend did that and it does fine. I'm thinking about doing it to mine. even with my revo i still spend a lot of time on my lid... but its all in how your drive i guess. but who knows, put on the sway bar and lower ur truck, you'll have a screamer... happy drivin.
Running sway bars gets just as annoying as not running sway bars after awhile. They keep the truck flat, but in grass or high traction areas, the truck isn't going to slide sidways regardless if you have sway bars or not. It has more to do with the center of gravity.
Do what nighthawk suggested. Lower the truck. Sway bars do help. Combined with lowering the truck it will really give you the best results.
