Diagram Ref No 3
Also referred to as a front stabiliser bar clamp, sway bar mounting bracket or anti-roll bar retaining clamp, this component forms part of the front anti-roll bar mounting assembly.
The Porsche front suspension incorporates an anti-roll bar, mounting brackets, bearing bushes and connecting links to help control vehicle body roll during cornering.
The anti-roll bar connects the suspension on both sides of the front axle and resists differences in vertical wheel movement, helping reduce excessive body roll.
For the anti-roll bar to operate correctly, it must be securely supported at its designated chassis mounting points.
The 9P1411063A clamp works with the associated anti-roll bar bearing bracket and fastening hardware to secure the stabiliser assembly in its intended position.
Manufactured to Porsche's original equipment specifications, the clamp is designed to match the specified mounting arrangement of compatible suspension systems.
Correct installation is important for maintaining secure anti-roll bar attachment, correct component positioning and proper operation of the front suspension.
This Genuine Porsche part is listed for several Porsche model generations, including the 911 (991 and 992), Boxster/Cayman (981) and 718 Boxster/Cayman (982).
It is also documented within selected Porsche Dynamic Chassis Control (PDCC) anti-roll bar assemblies.
During normal operation, the mounting components experience suspension movement, vibration, cornering forces and repeated changes in mechanical loading.
Although the clamp itself has no moving parts, it may become damaged through corrosion, impact, incorrect tightening or previous suspension repairs.
A cracked, bent or improperly secured clamp may allow unwanted movement within the anti-roll bar mounting assembly.
This can contribute to knocking noises, excessive play or incorrect positioning of the stabiliser components.
Replacing a damaged clamp with a Genuine Porsche component helps restore secure anti-roll bar mounting and maintain the original suspension assembly.
Ideal for Porsche suspension servicing, anti-roll bar repairs, front axle refurbishment and vehicle restoration, the Genuine Porsche Front Anti-Roll Bar Clamp provides a factory-specified replacement for the appropriate applications.
What This Product Does:
The front anti-roll bar clamp is a mechanical retaining component used to secure the anti-roll bar mounting assembly to the vehicle's front suspension structure.
The anti-roll bar helps reduce body roll during cornering by resisting differences in suspension movement between the left and right wheels.
The bar is supported through mounting bushes or bearing brackets that allow the suspension system to function as designed.
The clamp provides part of the fastening arrangement that holds these supporting components in place.
Its main functions include:
- Securing the front anti-roll bar assembly: Helps retain the stabiliser mounting components in their specified position.
- Supporting the anti-roll bar bearing bracket: Works with the associated bearing or mounting support.
- Maintaining correct suspension geometry: Helps preserve the intended positioning of the stabiliser bar.
- Reducing unwanted movement: Prevents excessive displacement caused by a damaged or loose mounting connection.
- Supporting body-roll control: Maintains the secure mounting required for the anti-roll bar to function correctly.
- Withstanding suspension loads: Operates within an assembly exposed to cornering forces and vibration.
- Maintaining left- and right-hand mounting: Uses the same reference on either side where specified.
- Reducing suspension noise: Helps prevent movement associated with defective mounting hardware.
- Supporting PDCC-equipped suspension systems: Provides the specified mounting arrangement in applicable active anti-roll bar assemblies.
- Maintaining original Porsche construction: Preserves the factory-designed suspension fastening arrangement.
The front anti-roll bar clamp is a durable fastening component, but corrosion, mechanical stress or incorrect installation may affect its condition.
Common signs of wear or damage include:
- Knocking noises from the front suspension: A loose mounting assembly may produce noises over bumps.
- Rattling from the front axle: Damaged or unsecured components may vibrate during driving.
- Visible cracking: Mechanical stress or previous overtightening may damage the clamp.
- Bent or distorted clamp: Impact damage may change its original shape.
- Corrosion: Road moisture and salt may cause deterioration.
- Damaged mounting holes: Distortion may prevent correct fastening.
- Loose anti-roll bar mounting: A defective clamp may allow movement at the supporting bracket.
- Missing or damaged fasteners: Incorrect retaining hardware may compromise attachment.
- Visible movement around the mounting point: The anti-roll bar support may no longer remain securely positioned.
- Damaged adjoining bush or bearing bracket: Excessive movement may affect neighbouring components.
- Uneven mounting alignment: The clamp may no longer sit correctly against the associated support.
- Evidence of impact damage: Kerb strikes or underbody contact may affect suspension mounting hardware.
- Poor fitment following repairs: Incorrect installation may prevent the clamp from seating correctly.
- Repeated loosening: Damaged threads or unsuitable hardware may prevent secure fastening.
- Abnormal suspension feel: Significant looseness within the anti-roll bar assembly may affect the vehicle's response during cornering.
Why Replacement Matters:
Replacing a damaged anti-roll bar clamp helps restore the correct mounting arrangement of the front suspension stabiliser system.
A cracked, distorted or loose clamp may no longer secure the anti-roll bar bearing bracket correctly.
Continued operation with an insecure mounting connection may allow additional movement and place unnecessary stress on the surrounding suspension hardware.
Where the anti-roll bar support is significantly loose, the effectiveness of the stabiliser assembly may also be affected.
Installing a Genuine Porsche replacement Front Anti-Roll Bar Clamp helps to:
- Restore secure anti-roll bar mounting: Replace a cracked, bent or damaged retaining component.
- Maintain correct suspension alignment: Keep the stabiliser support in its intended position.
- Reduce unwanted movement: Address looseness caused by a defective clamp.
- Help eliminate mounting-related knocking: Restore secure attachment where the clamp is confirmed as the cause.
- Support predictable handling: Maintain the anti-roll bar assembly required for normal body-roll control.
- Protect neighbouring suspension components: Reduce excessive movement at the bearing bracket.
- Replace corroded hardware: Renew clamps affected by significant deterioration.
- Support anti-roll bar servicing: Provide new retaining hardware during suspension refurbishment.
- Maintain correct PDCC assembly fitment: Preserve the intended attachment arrangement where applicable.
- Avoid unsuitable aftermarket fastening methods: Use the original Porsche mounting specification.
- Maintain factory suspension construction: Restore the designed connection between the stabiliser support and vehicle.
- Support long-term suspension reliability: Reduce the risk of problems caused by damaged mounting hardware.
- Maintain Genuine Porsche quality: Use an original equipment replacement component.
Replacement is recommended when the clamp is cracked, distorted, severely corroded, missing or unable to provide secure fastening.
If the associated bearing bracket, bush, mounting bolts or anti-roll bar is damaged, these components should be inspected and replaced as necessary.
