The Genuine Porsche 99134379208 stabilizer bar bush is the factory-specified rubber mounting used on the front anti-roll bar of Porsche 911 (991 series) and Boxster and Cayman (981 / 982) models. Designed to secure the stabilizer bar to the chassis, this bushing minimizes body roll, maintains precise suspension geometry, and ensures the characteristic Porsche steering feel and cornering stability.

• 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.

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.
