Information
Stabilizer bar / Drop link bush, Rear - 18mm
OE Match rear stabilizer bar drop link bush (18 mm) - direct replacement for Porsche part 91133379305. This 18 mm bush supports the stabilizer bar link where it connects to the suspension, helping maintain correct alignment and smooth handling.
Sold each, Fits left and right, 4 required per vehicle.
Fits:
Porsche 911 1974 - 1977 Rear
Porsche 911 Turbo 1975 - 1977
Diagram ref no 13
This OE Match rear stabilizer bar drop link bush is manufactured to closely replicate the original Porsche part in dimensions, material flexibility, and durability. Made from a resilient, high-grade rubber or urethane compound, it absorbs vibration, reduces noise, and provides the correct amount of compliance between the rear anti-roll bar drop link and its mounting point.
Over time, stabilizer bar bushes can deteriorate, harden, or crack due to exposure to road contaminants, heat, and normal wear. Worn bushes allow unwanted play in the anti-roll bar linkage, which can contribute to clunking noises, reduced cornering precision, and uneven handling. Replacing them with this OE Match bush restores proper support and helps maintain the intended suspension geometry and vehicle dynamics.
This bush is ideal for routine suspension maintenance, anti-roll bar servicing, or when replacing worn drop link components.
The stabilizer bar (anti-roll bar) drop link bush provides a flexible yet supportive mounting interface between the stabilizer bar link and the rear suspension. It helps transmit lateral forces cleanly while isolating vibration and reducing harshness - contributing to stable handling, reduced body roll, and refined ride quality.
Function:
• Cushions and supports the rear stabilizer bar link connection
• Maintains proper suspension geometry and handling characteristics
• Reduces noise, vibration, and harshness at the link interface
• Design for correct fit, alignment, and durability
• Made from durable compound to resist wear, heat, and road contamination
Worn or deteriorated stabilizer bar bushes can lead to sloppy handling, clunks over bumps, uneven cornering feedback, and increased body roll. Installing fresh OE Match bushes restores proper suspension responsiveness, improves steering precision, and helps maintain predictable handling under dynamic driving conditions.
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

Information
Lateral support clamp anti roll bar.
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.
