The stabilizer bar bushes hold the anti-roll bar securely in position while allowing controlled movement as the suspension operates. Correctly fitted bushes help reduce body roll, improve handling stability, and minimise knocking or looseness from the stabilizer bar mounting areas.

Functions
•  Replaces all 4 stabilizer bar bushes
•  Suitable for 22mm stabilizer bar applications
•  Supports and locates the anti-roll bar
•  Helps reduce body roll during cornering
•  Helps maintain stable suspension response
•  Reduces unwanted bar movement, knocking, and vibration
•  OE Match replacement set for Porsche 911 suspension service

Why Replace This Set?
Stabilizer bar bushes are exposed to road dirt, moisture, suspension load, vibration, and age. Over time, rubber bushes can crack, harden, split, compress, or wear, allowing excess anti-roll bar movement. Worn bushes may cause suspension knocking, vague handling, increased body roll, or failed inspection. Replacing all four bushes together helps restore balanced anti-roll bar support and suspension control.

When to Replace This Set
•  Suspension knocking or clunking is present
•  Stabilizer bar bushes are cracked, split, worn, or missing
•  Body roll feels excessive during cornering
•  Anti-roll bar or suspension service is being carried out
•  The stabilizer bar feels loose in its mounting points
•  The vehicle has failed inspection due to suspension bush wear
•  The car is undergoing Porsche 911 suspension restoration.

Where it fits on the car
This bush set fits at the stabilizer bar mounting points on Porsche 911 models from 1984 to 1989. It is used with a 22mm stabilizer bar.

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.

• Position: Front stabilizer bar (anti-roll bar) – chassis-mounted bushing.
•  Function: Reduces body roll, stabilizes front axle movement, and helps maintain proper suspension balance.

Worn stabilizer bushes can cause:
• Clunking or knocking noises over bumps
• Increased body roll or vague steering response
• Misalignment of the stabilizer bar
• Uneven tyre wear or degraded road feel

Replacing with a Genuine Porsche bushing restores correct bar positioning, suspension tightness and the crisp handling expected from a 911 / 981 / 982.
