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.

These bushes cushion the 20 mm diameter front anti-roll (sway) bar mountings, reducing metal-on-metal contact, dampening vibration and noise, and maintaining proper bar alignment under dynamic load. With worn or hardened bushes, the bar can move excessively, causing increased body roll, clunks or changes in handling.

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.

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.
