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

This kit is comprised of the following items:
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.

The rear stabilizer bar helps reduce body roll during cornering by linking suspension movement across the rear axle. The drop links connect the stabilizer bar to the suspension, while the bushes and clamps secure the bar to the chassis. Replacing these components together helps restore correct rear anti-roll bar operation and rear axle stability.
Functions
• Replaces rear stabilizer bar drop links
• Replaces rear stabilizer bar mounting bushes
• Includes stabilizer bar clamps and fixing bolts
• Helps secure the rear anti-roll bar correctly
• Supports stable rear suspension and handling response
• Helps reduce rear suspension knocking, looseness, and vibration
• OE Match repair kit for Porsche 996 Turbo rear stabilizer bar service.
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.
When to Replace This Kit
• Rear suspension knocking or clunking is present
• Rear drop links are worn, loose, noisy, or damaged
• Stabilizer bar bushes are cracked, split, compressed, or missing
• Clamps or bolts are corroded, seized, or damaged
• Rear anti-roll bar service or suspension refresh is being carried out
• Handling feels vague or body roll has increased
• The vehicle is undergoing Porsche 996 Turbo suspension restoration.
Where it fits on the car
This kit fits on the rear stabilizer bar / rear anti-roll bar assembly on Porsche 996 Turbo models. It services the rear bar link and mounting points across the rear axle.
