The Pontiac Grand Prix was made from 1962 to 2008 and is a full-size car that can be modified for more performance. One part that affects its performance is the sway bar.
A sway bar is a rigid length of tubular metal that is bolted to the suspension on either side of the car. Most vehicles use a sway bar at the front and rear, though some use only a front sway bar. When the vehicle is driven around a corner, sway bars act as a lever arm and force the wheel and tire towards the inside of the turn and the ground. This reduces body roll and makes the vehicle feel more stable and predictable.
A sway bar is replaced on a Pontiac Grand Prix to improve the car's handling. Generally speaking, stock sway bars are replaced with larger-diameter bars. The larger bars are more stiff and reduce body roll even further, which can make a big difference in a heavy car like the Grand Prix.
Replacing the sway bars on a Grand Prix is a straightforward procedure. The vehicle is lifted with a floor jack and supported on jack stands. The sway bar is then unbolted at either end where it connects to the suspension with drop links. The middle of the bar is also bolted to the chassis with brackets. The new sway bar is installed in the opposite manner of removal, and the car is lowered back to the ground.
