How does a drag racing anti-roll bar work?

With an anti-roll bar installed, the weight shift from the left front tire is counteracted by the anti-roll bars’ connection to the axle housing which keeps the vehicle’s weight from shifting to the right side, plants the tires evenly, and subsequently results in a level launch and consistent elapsed times.

Does anti-roll bar affect steering?

Since the stabilizer bar links are attached to the lower control arm, steering and handling are also negatively impacted when they begin to wear out. The steering wheel will appear to be “loose”, and the body will sway from left to right more due to the fact that the stabilizer bar links and bushings are wearing out.

Can anti-roll bars be too stiff?

The anti-roll bar works to resist roll, as its name suggests. But it has one other super-important role – it acts as a second spring to add spring stiffness at the tire, but only in cornering. But if we go too stiff with the springs, grip at the tires for braking and acceleration will be adversely affected.

When did the anti roll bar start in drag racing?

The drag race anti-roll bar has been around since the 1970’s, but racers would have to take their car to a competent chassis shop back in the day to have a custom anti-roll bar fabricated.

Do you need anti roll bars for rear suspension?

Anti-Roll bars do help a lot but they are another integral part of the entire rear suspension equation that needs to work in a balanced force with all other components of that rear suspension. Each piece is as critical as any other piece. Always remember that Anti-Roll Bars were not intended for adjusting Pre-Load.

How to adjust rear suspension for drag strip?

Leave the other three alone. ‘Pre-Load’ helps offset the torque from the engine. You will usually shorten the top right bar. Shortening the upper right bar adds weight to the right rear tire. A little does a lot. Try one ‘flat’ (on the adustment nut) at a time and keep track of how much you adjusted and the results.
