Front QuickChange™ Blade Style Sway bar

elephantracing

Front and Rear QuickChange™ Blade Style Sway Bar System

Blade style adjustable sway bar (anti roll bar) system is the ultimate choice for performance and tuning. This superior-quality system delivers unique features and advantages that are without rival. It is simply the best.The blade style adjuster mechanism varies roll stiffness with the angle of the blade. Set it vertically for full-stiff, horizontal for full-soft, and intermediate angles for other stiffness levels.

Blade style adjustment offers advantages over traditional adjustable sway bars including faster adjustment and superior geometry.

The rear sway bars fit 66mm bolt spacing on the sway bar mounts as equipped on 1978-1989 911 cars. 1965-1977 cars can be upgraded to the later 66mm type mounts

Perfect Geometry

Fixed-length arms ensure the angle of the drop links are not changed with stiffness adjustment. Geometry and kinematic behavior is always perfect. The bar always rotates freely, with low-friction, and without binding in all adjustment positions.

Traditional sway bars adjust roll stiffness by changing the length of the lever arm, at the same time changing the angle of the drop link. This can cause poor force-transmission angles in some positions. The result can be binding, high-friction, and excessive load on the mounts to the chassis.

Lightweight

Hollow bar reduces weight.

Fast and Easy Adjustment

No need to jack up the car or remove the wheels. Reach under the car, loosen one bolt to rotate the blade type adjuster. The angle of the blade defines the stiffness.
Literally about 1 minute to adjust, faster with practice.Infinitely variable adjustment lets you dial in the precise roll stiffness.

For track cars this fast-adjustment can be invaluable when time in the pits or paddock is short. Adjusting traditional sway bars is a lengthy process – jack up car, remove wheels, adjust, re-install wheels.

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.

Retro RSR Adjustable Sway Bar System

Retro appearance combined with modern performance and features make these adjustable sway bars (anti roll bar) a great choice for period-correct builds.

Drop links

Appearance similar to the RSR originals with a grey colour for a discreet and retro appearance. Left and right threaded precision rod ends make easy work of adjusting front drop link length. Adjustable length makes it easy to eliminate any preload on the bar. Teflon lined rod ends never require lubrication.

Lightweight

Hollow bars weigh half as much as similar solid bars delivering equal stiffness..
Bushings

Teflon impregnated bushings are grease and maintenance free and provide smooth operation and long life.

Through-body style front bar

Installs through the body same as the pre-1974 cars and the early turbo cars. Cars not originally equipped with a through-body sway bar should purchase the optional backer plate kit.

Retro-Look Arms

Steel arms are similar to the original RSR type and have drilled adjustment positions.

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.
