Replacing bushes in pairs restores uniform stabilizer bar support across both mounting points. This helps reduce noises, improves steering response consistency, and keeps handling predictable under cornering loads.
Function: The pair securely locates the stabilizer bar while allowing controlled rotation during suspension travel. Together they maintain the bar’s effectiveness in limiting body roll without unwanted movement or knocking.
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.
If one bush is worn, the other is usually not far behind. A mismatched pair can lead to uneven stabilizer bar support and persistent noises. Fitting a set of two helps restore factory-like feel, reduces repeat labour, and improves long-term reliability of the front anti-roll bar mounting.

• 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.

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.

OEMatch Anti Roll Bar Bushes — Control, Stability, Comfort
Anti-roll bar bushes secure the stabiliser bar to the chassis and control body roll, helping maintain steering precision and ride comfort. OEMatch offers replacements tailored for Porsche models to restore suspension balance, reduce noise and support consistent handling across road and light track use.
Available Types- Standard rubber bushes
- Polyurethane performance bushes
- Reinforced bushes with metal sleeves
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original anti roll bar bushes.
OE (Original Equipment) refers to parts matching original specifications for the anti roll bar bushes and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM anti roll bar bushes engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Anti-roll bar bushes sit between the bar and chassis mounts, allowing the stabiliser to twist and return while isolating vibration. Worn or degraded bushes alter roll control and can produce clunks or uneven cornering. OEMatch maintains a broad catalogue of Porsche-fit parts, with thousands of part numbers and extensive cross-references to support workshop servicing, restoration and routine maintenance.
- Restores roll control and cornering balance
- Reduces noise and vibration transmitted to the cabin
- Helps preserve steering precision and suspension geometry under load
- Material ageing such as rubber cracking, hardening or perishing
- Contamination from oil or road chemicals that degrades mount material
- Mechanical wear including corrosion of brackets, over-compression or repeated high loads
Many owners search for genuine or OEM anti roll bar bushes; OEMatch replacements are direct-fit alternatives designed to match the original form, fit and function. Replacing worn bushes restores predictable handling and reduces unwanted noise. For safety-critical suspension work, follow model-specific procedures or consult a qualified technician.
Advantages- Available in standard rubber for comfort and NVH control
- Polyurethane options for increased durability in demanding use
- Sleeved or reinforced designs that reduce unwanted movement at the mount
