OE Match
Size: 22mm diameter

It’s fitted on the rear anti-roll (sway) bar to support and cushion the bar’s mounting points. The stabilizer bar helps reduce body roll (lean) during cornering by transferring forces between the left and right sides of the suspension. The bushing’s job is to hold the bar in place while allowing it to move slightly and absorb vibration.
Fits:
Porsche 924 1978 REAR AXLE
Porsche 964 Turbo (965) REAR AXLE

Replacing worn or damaged sway bar bushings is crucial because:
• Ride comfort & handling suffer when bushings are worn—they get sloppy, allowing excessive play in the bar mount, which can lead to clunks, noise, or decreased steering precision
• Safety: A loose stabilizer bar means uneven handling, especially during sharp turns or emergency manoeuvres. Your car may feel “floaty” or unstable
• Prevent further damage: Neglected worn bushings can allow metal-on-metal contact, damaging the stabilizer bar itself, mounting brackets, or adjacent chassis components.
Signs that the PCG411313E bushing may be failing include:
• A clunking or knocking noise from the rear of the car over bumps or during turns.
• Squeaking or creaking sounds from the rear when going over irregular surfaces
• Noticeable body roll / lean during cornering (worse than it used to be
• Uneven tyre wear due to altered suspension geometry
• Visual inspection shows cracks, splitting, flat spots, or hardened rubber, or the bush is missing or loose.
If the stabilizer bar bushing fails and isn’t replaced, the bar can loosen and cause excessive movement, leading to clunks, knocks, and poor handling in corners. This not only reduces driving confidence and safety but can also overload other suspension parts, creating bigger problems and costly repairs over time.

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.
