The rear stabilizer bar helps reduce body roll during cornering by linking suspension movement across the rear axle. The drop links connect the stabilizer bar to the suspension, while the bushes and clamps secure the bar to the chassis. Replacing these components together helps restore correct rear anti-roll bar operation and rear axle stability.

•  Includes stabilizer bar clamps and fixing bolts
•  Helps secure the rear anti-roll bar correctly
•  Supports stable rear suspension and handling response
•  Helps reduce rear suspension knocking, looseness, and vibration
•  OE Match repair kit for Porsche 996 Turbo rear stabilizer bar service.

Why Replace This Kit?
Rear stabilizer bar components are exposed to road dirt, moisture, suspension load, vibration, heat, and age. Drop link joints can wear or develop play, bushes can crack or compress, clamps can corrode, and bolts can seize or become damaged during removal. Worn components may cause rear suspension knocking, increased body roll, vague handling, uneven response, or failed inspection. Replacing the drop links, bushes, clamps, and bolts together helps restore a secure and balanced rear anti-roll bar assembly.

When to Replace This Kit
•   Rear suspension knocking or clunking is present
•   Rear drop links are worn, loose, noisy, or damaged
•   Stabilizer bar bushes are cracked, split, compressed, or missing
•   Clamps or bolts are corroded, seized, or damaged
•   Rear anti-roll bar service or suspension refresh is being carried out
•   Handling feels vague or body roll has increased
•   The vehicle is undergoing Porsche 996 Turbo suspension restoration.

Where it fits on the car
This kit fits on the rear stabilizer bar / rear anti-roll bar assembly on Porsche 996 Turbo models. It services the rear bar link and mounting points across the rear axle.

Constructed from high-quality rubber compound for optimum durability and performance, the anti-roll bar bush plays a critical role in maintaining suspension stability, steering precision and ride comfort. Genuine Porsche components ensure factory-correct fitment and preserve the handling characteristics engineered into the vehicle.

What This Product Does:

Secures the front anti-roll bar to the chassis mounting points.
Allows controlled movement of the anti-roll bar during suspension operation.
Reduces vibration and noise transmitted through the suspension system.
Helps maintain effective anti-roll bar performance.
Supports vehicle stability during cornering.
Contributes to precise steering response and predictable handling.

Symptoms Of Wear Or Failure:

Knocking, squeaking or creaking noises from the front suspension.
Excessive body roll during cornering.
Reduced steering precision.
Increased suspension movement or looseness.
Vehicle feeling less stable during directional changes.
Uneven handling characteristics.
Visible cracking, splitting or deterioration of the rubber bush.
Excessive movement of the anti-roll bar within its mounting brackets.

Why Replacement Matters:

Anti-roll bar bushes are exposed to constant suspension movement, vibration, road contamination, moisture and temperature fluctuations. Over time, the rubber material can harden, crack, compress or deteriorate, reducing its ability to properly support and isolate the anti-roll bar.
Worn bushes can compromise the effectiveness of the anti-roll bar system, leading to increased body roll, suspension noise and reduced handling precision. Excessive movement of the anti-roll bar may also accelerate wear on related suspension components and affect overall vehicle stability.
Replacing worn anti-roll bar bushes restores proper stabiliser bar operation, improves handling performance and helps maintain the refined driving characteristics expected from a Porsche. Genuine Porsche replacement bushes provide exact fitment, factory-level quality and long-term durability for reliable suspension performance.

Lateral support clamp anti roll bar. Various sizes for Porsche

Product Information

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 Bar Bushes

Porsche Anti-Roll Bar Bushes | Design911 Suspension Components for Precision, Grip & Stability

Anti-roll bar bushes (also known as stabiliser bar bushes) are small but critical components within your Porsche’s suspension system. They secure the anti-roll bar to the chassis, allowing controlled movement that reduces body roll during cornering and improves handling stability. Properly functioning bushes help maintain suspension geometry, steering precision, and ride comfort — key attributes that define Porsche’s dynamic driving performance.

At Design911, we offer a full range of anti-roll bar bushes, crafted from advanced rubber, polyurethane, and performance-grade materials. Each bushing is engineered for exact fitment, durability, and vibration isolation. Perfect for routine servicing, performance upgrades, or complete restorations, our range helps restore suspension balance and ensures consistent road holding and control.

What Do Anti-Roll Bar Bushes Do?

Anti-roll bar bushes act as cushioning mounts between the anti-roll bar and chassis, absorbing vibration and allowing controlled articulation of the bar.

Core Functions:
• Reduce body roll by supporting bar movement during cornering.
• Provide cushioning to minimise noise and vibration.
• Maintain correct anti-roll bar alignment under load.
• Help distribute cornering forces evenly for improved grip.
• Enhance suspension comfort and steering response.

In good condition, anti-roll bar bushes keep your Porsche stable, predictable, and agile — whether on road, track, or everyday driving.

Why Do Anti-Roll Bar Bushes Fail or Degrade?

Constant flexing, pressure, and exposure to environmental factors gradually wear down bush materials, affecting handling and comfort.

Common Causes of Failure Include:
• Cracking, hardening, or perishing of rubber due to age or heat.
• Oil contamination softening and weakening bush material.
• Corrosion or movement in brackets wearing the bush housing.
• Over-compression or deformation from high-performance driving.
• Excessive vibration causing accelerated wear.

When bushes fail, symptoms often include clunking noises, poor cornering balance, and reduced steering sharpness — all signs that replacement is needed to restore your Porsche’s precision.

Why Replace or Upgrade Your Porsche Anti-Roll Bar Bushes?

Replacing worn bushes restores suspension control, comfort, and steering precision. Upgrading to polyurethane or performance-grade bushes provides sharper handling and greater durability for spirited or track-focused driving.

Key Benefits:
• Restores handling stability and reduces body roll.
• Eliminates suspension noise, vibration, and harshness.
• Improves steering response and cornering feedback.
• Available in rubber and performance polyurethane options.
• Fits Porsche 911, 944, 968, Boxster, Cayman, Cayenne, and Macan models.
• Ideal for suspension servicing, restoration, or performance tuning.

Design911’s Porsche anti-roll bar bushes offer precision, performance, and reliability — ensuring your Porsche continues to handle with confidence and control.

Highlights

• Premium Porsche anti-roll bar bushes and stabiliser mounts.
• High-quality rubber or polyurethane construction.
• Designed for precise fitment and vibration absorption.
• Improves handling, stability, and suspension comfort.
• Compatible with classic and modern Porsche models.
