• Application: Rear anti-roll (stabilizer) bar bushing - fits around the 19.8 mm diameter stabilizer bar to mount it to the rear suspension subframe. Two bushings (left and right) are typically required per vehicle.

The anti-roll bar bushing cushions and secures the stabilizer bar to the rear suspension structure. This part helps maintain the correct position and movement control of the rear anti-roll bar, reducing unwanted body roll in corners and stabilizing the chassis during acceleration, braking, and steering.

Over time, the factory rubber in anti-roll bar bushings can harden, crack, or break down due to heat, age, and load cycles. Worn bushings can lead to:
• Increased body roll and reduced handling precision
• Clunking or knocking noises from the rear suspension
• Uneven tire wear
• Loose or sloppy cornering response

Replacing bushings restores correct fitment and suspension geometry, improving stability, road feel, and overall driving confidence. Spyder Performance

Replace the rear anti-roll bar bushings if you notice:
• Clunking or rattling from the rear suspension
• Excessive body lean when cornering
• Visible cracks, distortion, or missing rubber on existing bushings
• During suspension overhaul or anti-roll bar removal
• Elevated noise or vibration through the rear of the car

What stabilizer bar bush does:
• Cushions and secures the stabilizer (anti-roll) bar to the chassis, reducing vibration and road noise
• Helps maintain proper sway bar function by allowing the bar to pivot while minimizing unwanted movement
• Preserves handling precision and vehicle stability during cornering by preventing excessive body roll.

Over time, bushings can harden, crack, or deteriorate, which leads to play in the stabilizer bar mount, increased noise, sloppy handling, or even suspension misalignment. Replacing bushing restores correct stiffness, reduces unwanted vibration or sway, and helps preserve the original handling characteristics of the vehicle.

Diagram Ref No 2

Mounted between the rear anti-roll bar and its retaining brackets, the bush securely supports the stabilizer bar while still allowing the controlled rotational movement required as the suspension moves.

Over time, the original rubber bushes can harden, crack or develop excessive clearance around the stabilizer bar. Replacing worn bushes helps restore secure mounting, reduce suspension noise and improve the consistency of rear suspension response.

What This Product Does:
The rear stabilizer bar connects the suspension on the left and right sides of the vehicle and helps reduce body roll during cornering.

The stabilizer bar bushes hold the bar securely to the chassis while allowing it to twist as suspension loads change.

Their main functions include:

  • Supporting the rear stabilizer bar
  • Maintaining correct anti-roll bar positioning
  • Allowing controlled rotational movement
  • Helping reduce body roll during cornering
  • Preventing excessive movement within the mounting brackets
  • Isolating vibration and suspension noise
  • Supporting predictable rear suspension behaviour
  • Helping maintain consistent handling response

The bush itself does not increase the stiffness of the stabilizer bar. Instead, it ensures the bar is securely supported so it can operate as intended.

Symptoms Of Wear Or Failure:
Stabilizer bar bushes are continually subjected to suspension movement, road contamination, moisture and changes in temperature.

Common symptoms of worn rear anti-roll bar bushes include:

  • Knocking or clunking from the rear suspension
  • Rattling when driving over uneven roads
  • Squeaking from the anti-roll bar mounting area
  • Excessive movement of the stabilizer bar
  • Visible cracking or splitting of the rubber
  • Bush becoming hardened or distorted
  • Enlarged or worn internal bore
  • Reduced suspension precision
  • Increased body movement during cornering
  • Rear suspension feeling less controlled
  • Stabilizer bar moving inside its mounting bracket
  • Wear discovered during suspension inspection

Knocking noises can also be caused by worn drop links, control arms or other suspension components, so the complete rear suspension should be inspected.

Why Replacement Matters:
The stabilizer bar can only work effectively when it is securely mounted.

If the bushes become worn or compressed, the bar can move within its brackets before it begins transferring suspension load from one side of the vehicle to the other.

This unwanted movement can result in:

  • Knocking and rattling noises
  • Reduced anti-roll bar effectiveness
  • Less precise handling
  • Increased suspension movement
  • Inconsistent cornering response
  • Additional stress on related suspension components

Replacing worn bushes restores a tighter connection between the stabilizer bar and chassis, helping the anti-roll bar respond immediately as suspension loads change.

Fresh bushes can therefore improve both refinement and handling by reducing unwanted movement and restoring the original operating position of the stabilizer bar.

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.
• Perfect for maintenance, restoration, or performance upgrades.
