Anti-Roll Bars (ARB’s) play an important role in a vehicle’s suspension system, helping to reduce body roll by transferring cornering load from one side of a vehicle to the other.
Often mounted to the vehicle’s chassis with rubber bushes, these bushes ensure the bar works as intended. To prevent the anti-roll bar from moving laterally within its mounts when turning, OE manufacturers will either bond the bushes to the bar, add dead-stops to the bar itself, or rely solely on the clamping pressure of the rubber.
But what happens when those bushes wear and need to be replaced? Often anti-roll bars with bonded bushes come as a costly complete assembly, so the alternative is to fit a more cost-effective unbonded polyurethane replacement, like the many we offer.
In most cases, friction from the bush will prevent any side-to-side bar movement. Still, when turning aggressively or cornering at higher speeds, a laterally shifting anti-roll bar decreases the efficiency and effectiveness of the bar, changing the dynamics of your suspension system in unpredictable ways. It also poses the risk of the bar fouling on other areas of the vehicle or suspension system.
OE Match rear stabilizer bar repair kit for Porsche 996 Turbo models. This complete rear anti-roll bar service kit includes drop links, stabilizer bar bushes, mounting clamps, and bolts to help restore rear suspension control and reduce unwanted movement or knocking. This kit includes the key components commonly required when refreshing the rear stabilizer bar mounting and linkage system.

Why Replace This Kit?
Rear stabilizer bar components are exposed to road dirt, moisture, suspension load, vibration, heat, and age. Drop link joints can wear or develop play, bushes can crack or compress, clamps can corrode, and bolts can seize or become damaged during removal. Worn components may cause rear suspension knocking, increased body roll, vague handling, uneven response, or failed inspection. Replacing the drop links, bushes, clamps, and bolts together helps restore a secure and balanced rear anti-roll bar assembly.

Why Replacement Matters
A distorted, corroded or damaged bracket can allow the stabiliser mounting to move away from its intended location. Replacing the affected component restores the mounting arrangement and may address noise caused by movement within the assembly. The adjacent bush, clamp, bolts, nuts and mounting surfaces should be inspected during the repair, with worn or damaged supporting parts renewed as required.
FAQs
- How should suitability be confirmed?
Check the model, production year, VIN and fitted PR equipment codes. PDCC suspension components can vary according to the vehicle specification. - Should both mounting brackets be inspected?
Yes. The diagrams record two brackets within each applicable assembly, so the opposite mounting and its associated hardware should also be checked for wear or corrosion. - Can mounting noise come from another component?
Yes. Similar symptoms may be caused by a worn bush, clamp, anti-roll bar link or loose fixing, so inspection is recommended before parts are replaced.
Check fitment for your specific vehicle, including model, year and PR equipment codes, before ordering. VIN verification is recommended for PDCC suspension components.

Diagram Ref No 2
Also described as a front stabiliser bar mounting bush or sway bar bearing, this component forms part of the mounting arrangement that holds the anti-roll bar in its correct position.
The anti-roll bar is an important element of the suspension system. It helps reduce excessive body roll during cornering by resisting differences in suspension movement between the left and right wheels.
For the anti-roll bar to work correctly, it must remain properly located within its mounting points while accommodating the controlled movement associated with suspension travel.
The Porsche bearing bracket 99134379207 provides this support, helping maintain the intended position of the front stabiliser bar and reducing unwanted movement within the mounting assembly.
On vehicles such as the Porsche 911 Carrera and mid-engined Boxster and Cayman, accurate suspension response is central to the driving experience.
Even relatively small suspension mounting components can influence the way loads are transmitted through the chassis.
Over time, anti-roll bar mounting bushes can deteriorate through repeated suspension movement, temperature changes, road contamination and general ageing.
Worn mounting material may develop cracks, compression or excessive clearance around the stabiliser bar.
When this happens, the anti-roll bar can move more than intended, potentially causing knocking, rattling or creaking noises from the front suspension.
Severe deterioration may also affect the consistency of the anti-roll bar's response during cornering.
Replacing a defective bearing bracket with Genuine Porsche part number 99134379207 helps restore the correct factory mounting arrangement, maintaining the original suspension characteristics.
This part is particularly suitable for front suspension repairs, maintenance of noisy stabiliser bar mounts and replacement of deteriorated anti-roll bar bushes.
