Yeah cheers mate, I was not sure if the accuair partly acted like a sway bar or not but yeah like cook mentioned it does not so i will deffenantly be running the sway bar. Engine wise i plan to have about 650-700hp + a extra 150 hp on the bottle so i plan to drive the truck hard lol so a sway bar is a must! While on the subject can anyone reccomend some good shocks for the front and if so part numbers or links to them? The truck is a 1990 obs rcsb, cheers ryanKeeping the sway bar would be best for the reason that cook explained. It will help keep the truck from rolling over in the turn. But, I have no sway bar and I have accuair. The accuair does nothing to help with sway. It takes about 45 seconds to make an adjustment when driving. I drive slow in turns so I don't really notice the sway bar being gone.
