This bolt is used in the stabiliser bar / anti-roll bar mounting system on selected Porsche models.
What This Part Does / Functions
• Secures the stabiliser bar bush clamp to the vehicle
• Helps hold the anti-roll bar mounting bracket in place
• Maintains correct stabiliser bar positioning
• Supports proper suspension and anti-roll bar operation
• Helps prevent movement, knocking or looseness at the bush clamp
• Provides correct OE Porsche thread, length and head specification
• Replaces a corroded, damaged, stretched or missing original bolt
• Maintains factory Porsche suspension hardware quality.
Why Replace This Part?
Stabiliser bar clamp bolts are exposed to road dirt, water, corrosion, suspension load and repeated service removal. Over time, the bolt can rust, seize, round off or become damaged. A worn or incorrect bolt may not clamp the stabiliser bar bush bracket securely, which can lead to knocking noises, unwanted bar movement or poor suspension performance. Replacing it with a Genuine Porsche OE bolt helps ensure the stabiliser bar bush clamp is secured correctly using factory-specified hardware.
When to Replace This Part
• When replacing stabiliser bar bushes
• When replacing anti-roll bar clamps or brackets
• If the original bolt is corroded, seized, rounded or damaged
• If the bolt is missing or incorrect
• During suspension overhaul or restoration
• If knocking noises are traced to loose stabiliser bar mounting hardware
• When removing the stabiliser bar assembly for service
• When rebuilding the suspension with correct Genuine Porsche hardware.
Where It Fits on the Car
This bolt fits at the stabiliser bar / anti-roll bar bush clamp mounting point. It secures the clamp or bracket that holds the stabiliser bar bush in position.

The bolt holds the stabiliser bar bush clamp in place, keeping the anti-roll bar correctly secured to the chassis or suspension mounting point. A secure clamp fixing helps the stabiliser bar operate correctly and reduces unwanted movement, knocking, or looseness in the suspension system.
Functions
• Replaces the stabiliser bar bush clamp bolt
• Secures the anti-roll bar bush clamp
• Helps keep the stabiliser bar correctly located
• Supports stable suspension and anti-roll bar operation
• Used during anti-roll bar bush, clamp, or suspension service
• Replaces corroded, rounded, stretched, damaged, or missing original bolts
• OE Match replacement fixing for Porsche suspension repair.
Why Replace This Part?
Stabiliser bar clamp bolts are exposed to road dirt, moisture, corrosion, vibration, and suspension movement. A worn, corroded, rounded, seized, or damaged bolt can make correct clamp installation difficult and may reduce secure mounting of the anti-roll bar bush. Replacing the bolt during stabiliser bar bush or clamp service helps restore reliable suspension fixing and correct anti-roll bar operation.
When to Replace This Part
• The stabiliser bar bush clamp is being removed or replaced
• Anti-roll bar bushes are being renewed
• The original bolt is corroded, rounded, seized, stretched, or damaged
• Suspension knocking or movement is being investigated
• Anti-roll bar service or restoration is being carried out
• The bolt is missing or no longer tightens correctly
• Preventative replacement is required during suspension repair.
Where it fits on the car
This bolt fits at the stabiliser bar bush clamp mounting point. It secures the clamp that holds the anti-roll bar mounting bush in position. Exact location can vary depending on model and front or rear stabiliser bar layout.

Porsche Suspension & Axle Parts
Porsche suspension systems are engineered with precision to deliver sharp handling, ride comfort, and maximum performance. Whether on the road or track, your Porsche relies on a finely tuned suspension and axle setup to keep you in control. When components wear out, the ride becomes rough, handling suffers, and safety can be compromised.
At Design911, we supply a full range of suspension and axle parts for classic and modern Porsche models — from shock absorbers and coil springs to control arms and ball joints - helping you maintain your car’s legendary driving dynamics.
Signs of Worn Shocks or Struts
Shock absorbers and struts are essential for keeping your
Porsche stable over bumps and through corners. Some signs they may need
replacement include:
- Excessive
Bouncing – car continues to bounce after hitting bumps
- Poor
Cornering Stability – leaning hard into corners, reduced grip
- Fluid
Leaks – damp or oily patches on shocks/struts
- Uneven Tyre Wear – poor damping leads to increased tyre wear
If left unchecked, worn shocks or struts not only reduce ride comfort but can also compromise safety.
Common Porsche Suspension Issues
Different Porsche models can face specific
suspension-related faults. The most frequent include:
- Lower
Track Control Arm Bushings - Failure
causes squeaking noises, uneven tyre wear, and eventually knocking sounds
over rough roads.
- Broken
Coil Springs - Seen
in models such as the Porsche Boxster. Symptoms include groaning noises
when steering and clicking or knocking over bumpy surfaces.
- Leaking
or Worn Shock Absorbers - Identified
by damp, oily residue on the shock body. This is one of the most common
suspension failures over time.
- Ball Joint Wear - Worn joints reduce steering precision and can lead to loss of control if ignored.
Fortunately, most of these issues can be resolved by simply replacing the affected parts with OEM or high-quality aftermarket components.
