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.

• 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

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.

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.
