Powerflex's Range...

Road Series – for Road and fast Road use.

POWERFLEX Road Series bushes improve your cars’ road holding and chassis performance by controlling the amount of unwanted flex in the suspension. This means the suspension is doing what it is supposed to. It means your tyres have greater contact with the road at all times, therefore, improving safety and performance. Correctly formulated polyurethane is as good if not better at noise, vibration and harshness suppression when compared to worn rubber. Our Road bushes offer Prolonged tyre life, Improved performance, Increase safety, and Greater cost-effectiveness.

Black Series – for Track and Motorsport use.

POWERFLEX Black Series bushes are manufactured using our Black 95 Shore A compound to provide maximum control of chassis geometry. They are designed for the Track, ready to Race and are engineered to be the best. This compound can be up to 80% more resistant to load than standard rubber and 25% stiffer than our purple performance material. If your requirements are purely for the ultimate in handling and chassis performance then Powerflex Black Series are unique, offering the most precise and accurate alignment for your chassis.

Heritage Collection – for Classic and Restoration use.

POWERFLEX Heritage Collection bushes are manufactured using modern-day materials with properties biased for the road. These dark grey coloured bushes will improve any collector’s car, whilst retaining the same standard appearance of a rubber bush. Our new range speaks to the growing demand for quality replacement parts that have an aesthetic in keeping with’ the look of the original part and restoration project as a whole whilst carrying all of the performance and longevity benefits offered by Powerflex’s unique blend of polyurethane. Going a step further than simply using the same material and durometer of hardness for all of our parts, each part location has its own shore designation to ensure improved suspension performance without discomfort or vibration, all of which ship in our new ‘Classic’ Dark Grey colour suitable for all road-based applications.

Lateral support clamp anti roll bar. 

powerflex

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.
