Anti Roll Bars (also known as anti-sway bars, sway bars or lower tie bars) affect the handling of the car on the lower end of the suspension. Sway bars tie the lower suspension components together across the front or back, and affect a car's over steer and under steer. Sway bars will keep your car flat in turns instead of leaning over to one side. They distribute energy from the side of the car with all the force from the turn on it to the other side of the car, bringing the whole car down flat instead of leaning to one side. Of course the car will still lean some, but not as much. Sway bars provide better cornering especially at high speeds and work very well in conjunction with strut tower bars. However, they can have an adverse affect in off-road situations by leaving one tire completely off the ground.

Anti-Roll Bars (ARB’s) play an important role in a vehicle’s suspension system, helping to reduce body roll by transferring cornering load from one side of a vehicle to the other.

Often mounted to the vehicle’s chassis with rubber bushes, these bushes ensure the bar works as intended. To prevent the anti-roll bar from moving laterally within its mounts when turning, OE manufacturers will either bond the bushes to the bar, add dead-stops to the bar itself, or rely solely on the clamping pressure of the rubber.

But what happens when those bushes wear and need to be replaced? Often anti-roll bars with bonded bushes come as a costly complete assembly, so the alternative is to fit a more cost-effective unbonded polyurethane replacement, like the many we offer.

In most cases, friction from the bush will prevent any side-to-side bar movement. Still, when turning aggressively or cornering at higher speeds, a laterally shifting anti-roll bar decreases the efficiency and effectiveness of the bar, changing the dynamics of your suspension system in unpredictable ways. It also poses the risk of the bar fouling on other areas of the vehicle or suspension system.

About Anti Roll Sway Bar

Anti Roll Bars / Sway Bars – Improved Handling and Body Control

Anti roll bars, also known as sway bars, are suspension upgrade components designed to reduce body roll during cornering and improve overall vehicle stability. By linking the left and right sides of the suspension, anti roll bars resist excessive chassis movement, helping the car stay flatter through corners and delivering sharper, more predictable handling.

At Design911, our range of anti roll bars includes high-quality OE replacement and performance upgrade options from trusted suspension brands. Whether you’re refreshing worn factory components or upgrading for fast-road and track use, anti roll bars are one of the most effective ways to enhance handling without compromising ride comfort.

What Do Anti Roll Bars / Sway Bars Do?

Anti roll bars are torsion bars mounted across the suspension axle that control lateral body movement when cornering. Their main functions include:

  • Reducing body roll during turns
  • Improving cornering balance and grip
  • Enhancing steering response and driver confidence
  • Distributing load more evenly across the suspension

By limiting excessive chassis lean, sway bars allow tyres to maintain better contact with the road, improving traction and control.

Why Upgrade Your Anti Roll Bars?

Upgrading anti roll bars is a popular suspension modification because it offers:

  • Noticeable handling improvements with minimal impact on ride comfort
  • Better control during spirited driving or track use
  • Improved balance between front and rear suspension
  • Reduced understeer or oversteer when correctly matched

Performance anti roll bars are often adjustable, allowing fine-tuning of suspension balance to suit driving style, tyre choice and road conditions.

When Should You Replace or Upgrade Anti Roll Bars?

Anti roll bars should be replaced or upgraded when:

  • Factory suspension feels soft or unstable during cornering
  • Rubber bushes or mounting hardware are worn or damaged
  • Upgrading other suspension components such as springs or dampers
  • Preparing a vehicle for fast-road, track day or performance use

Replacing tired components or upgrading to performance sway bars restores precise handling and improves overall driving enjoyment.

At Design911, we supply anti roll bars and suspension upgrades that meet professional workshop standards and enthusiast expectations.
