Sway bars are one of the biggest improvements to your vehicles handling needs. Also known as “anti sway bars”, sway bars do just that, reduce the amount of chassis roll. There is two types of handling problems to be corrected. Over steer and under steer. If you have ever driven a front wheel drive car fast into a turn and felt it push towards the outside or not come around where you want it to go, this is under steer. All wheel drive cars can experience some of this as well. The more common feeling of over steer is what anyone who has driven a rear wheel drive car and punched the gas in a turn has experienced. Ideally you want to find a neutral balance for both. Some drivers of all wheel drive vehicles like to induce more over steer because of the AWD system pulling them through the turns. Adjustable sway bars provide this balance by having a larger diameter than stock and adjustment holes on the bar. To have the bar perform stiffer, the inner most hole to the bend will do the trick. To soften the sway bar, you want to use the outer most hole. Sway bars work excellent in conjunction with a set of sway bar links.
