The sway bar (stabilizer bar) is used as an anti-rolling device on almost every type of vehicle. There is different types and different ways to install a
sway bar.
The universal type way bar is the most common in asphalt circle track racing. It is used simply by using two eye bolts that are threaded to have adjustments
on the load of the bar. The bar simply rests up against the left side lower control arm and on the right side lower using an attaching assembly like a bolt
or heim joint.
The torsion type sway bar is more common on heavier cars like a Winston Cup type car. This bar has detaching arms on both sides and the main bar has a spline
on each end for easy settings. Normally the bar is attached on both the right side and the left side with a heim joint assembly. This type of bar is normally
mounted solid to the chassis and uses heim joints as its adjustment.
There are several sway bar sizes to choose from. Bar selection is critical in your chassis set-up's because it determines the cars willingness to roll over.
In most cases a smaller bar is used to help the car turn when entering the corner, the adverse affect is that there is less forward traction. A larger bar is
used to help tighten the car up on corner entry, the adverse affect of this is the car becomes tighter in the middle and off the corner also.
