Stabilizer bar / Drop link bush kit, Rear - 18mm
High-quality OE Match suspension service kit designed to replace all rear anti-roll bar drop link bushes on Porsche 911 models fitted with an 18 mm rear stabilizer bar. Supplied as a complete set, it allows both sides of the rear suspension to be refreshed at the same time.
SET OF 4

Fits:
Porsche 911 1974 - 1977 Rear
Porsche 911 Turbo 1975 - 1977

This OE Match set of four is ideal for suspension refresh work, anti-roll bar servicing, or preventative maintenance, providing a cost-effective alternative to genuine OE parts while maintaining correct fit and function.  

The stabilizer bar drop link bushes provide a flexible mounting interface between the rear anti-roll bar links and suspension components. As a complete set, they ensure uniform load transfer, controlled body roll, and reduced vibration across both sides of the rear suspension.

Function:
• Supports and cushions rear stabilizer bar drop link connections
• Maintains correct suspension geometry and roll control
• Reduces noise, vibration, and harshness at the link interface
• Design for correct fit, alignment, and durability
• Supplied as a full rear axle set for balanced handling

Replacing stabilizer bar bushes individually can lead to uneven suspension behaviour. Installing a complete OE Match set ensures consistent compliance on both sides of the rear axle, improving cornering stability, steering feedback, and overall ride quality while eliminating suspension noise caused by worn bushes.

When to replace:
•  Noticeable clunking or squeaking from the rear suspension
•  Reduced handling precision or increased body roll
•  Cracked, hardened, or visibly worn bush material
•  After replacing stabilizer bar links or other suspension components
•  As part of a comprehensive suspension refresh

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.
