Also known as a stabiliser mounting or sway bar bush. The bushing secures the stabiliser to the chassis bracket and ensures optimal transfer of roll‐control forces during cornering, while maintaining isolation for a quiet, refined ride.

Porsche 986 Boxster 1997-04 2.5L / 2.7L
* Cars with standard suspension
Porsche 996 C2 Coupe
* Fits only Manual cars with standard suspension

• Position on Vehicle: Front axle, stabiliser (anti‐roll) bar mounting – bush between bar and chassis bracket.
• Applications: Suitable when the original stabiliser bar bush is worn, cracked, flattened or causing noise and reduced rear/ front roll-control. Essential for restoring proper roll-bar function and chassis behaviour.
The stabiliser bar (sway bar) plays a key role in controlling body roll and ensuring lateral stability during cornering. If the bushings that mount it to the chassis are worn, they permit unwanted movement, causing clunks, loose feel, excessive body lean or uneven tyre wear. Replacing these bushings with correctly sized units ensures the roll-bar functions correctly and your suspension performs as intended.
When and why to replace:
• You hear a knocking or clunking sound when cornering, going over bumps or when driving over rough roads.
• The front suspension feels vague or exhibits more body roll than normal.
• Visual inspection shows cracks, flattening or deformation of the bush.
• As part of a front suspension refresh, alignment work or whenever you're renewing multiple components for improved handling.

• 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

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
