Information
Stabilizer Bar Bush Front, Size: 22mm
This OE Match stabilizer bar bush is a replacement rubber suspension bush for the 22mm anti-roll bar. It is designed to match the original-style fitment and function, helping restore secure mounting and smooth stabilizer bar operation.
Sold individually, 4 required per vehicle.
Fits:
Porsche 911 1984-86 3.2L and Turbo Front axle - Please choose by size
Porsche 911 1987-89 3.2L and Turbo Front axle
Diagram ref no 24
The stabilizer bar bush holds the anti-roll bar securely in position while allowing controlled movement as the suspension operates. A correctly fitted bush helps reduce body roll, improve handling stability, and minimise knocking or looseness from the stabilizer bar mounting area.
Functions
• Replaces the 22mm stabilizer bar bush
• 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
• Suitable for suspension refresh or anti-roll bar service
• OE Match replacement for Porsche 911 suspension repair.
Why Replace This Part?
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 worn bushes helps restore correct anti-roll bar support and suspension control.
When to Replace This Part
• 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 fits at the stabilizer bar mounting points on Porsche 911 models from 1984 to 1989. It is used with a 22mm stabilizer bar.

Information
Stabilizer bar bush, Rear.
Size: 22mm diameter
Sold each.
It’s fitted on the rear anti-roll (sway) bar to support and cushion the bar’s mounting points. The stabilizer bar helps reduce body roll (lean) during cornering by transferring forces between the left and right sides of the suspension. The bushing’s job is to hold the bar in place while allowing it to move slightly and absorb vibration.
Fits:
Porsche 924 1978 REAR AXLE
Porsche 964 Turbo (965) REAR AXLE
Diagram ref no 17.
Replacing worn or damaged sway bar bushings is crucial because:
• Ride comfort & handling suffer when bushings are worn—they get sloppy, allowing excessive play in the bar mount, which can lead to clunks, noise, or decreased steering precision
• Safety: A loose stabilizer bar means uneven handling, especially during sharp turns or emergency manoeuvres. Your car may feel “floaty” or unstable
• Prevent further damage: Neglected worn bushings can allow metal-on-metal contact, damaging the stabilizer bar itself, mounting brackets, or adjacent chassis components.
Signs that the PCG411313E bushing may be failing include:
• A clunking or knocking noise from the rear of the car over bumps or during turns.
• Squeaking or creaking sounds from the rear when going over irregular surfaces
• Noticeable body roll / lean during cornering (worse than it used to be
• Uneven tyre wear due to altered suspension geometry
• Visual inspection shows cracks, splitting, flat spots, or hardened rubber, or the bush is missing or loose.
If the stabilizer bar bushing fails and isn’t replaced, the bar can loosen and cause excessive movement, leading to clunks, knocks, and poor handling in corners. This not only reduces driving confidence and safety but can also overload other suspension parts, creating bigger problems and costly repairs over time.
