Guida all'acquisto delle biellette della barra stabilizzatrice
Ultimo aggiornamento: 24 aprile 2026
Anti-roll bar links (drop links) connect the anti-roll bar to the suspension strut or lower arm. They transmit the bar's stabilising force to the suspension, reducing body roll in corners. Worn links are one of the most common causes of knocking noises from the front suspension and are a frequent MOT advisory.
Anti-roll bar link wear symptoms
Drop links contain ball joints at each end that wear and develop play. The symptoms are most noticeable over rough surfaces and when cornering.
- Knocking or rattling from the front suspension over bumps and potholes
- Clunking noise when turning at low speed into driveways or car parks
- Increased body roll in corners compared to when links were new
- Play visible when the link is grabbed and rocked by hand
- MOT advisory or failure for worn anti-roll bar link ball joints
Link replacement
Anti-roll bar links are one of the simplest suspension components to replace. They bolt between the strut and the anti-roll bar.
- Always replace links in pairs (both sides) for balanced handling
- Use a hex key in the ball joint stud to prevent it spinning while undoing the nut
- Apply copper grease to the threads and mounting faces to aid future removal
- Check the anti-roll bar bushes while the links are off — they often wear at a similar rate

Domande frequenti
How long do anti-roll bar links last?
Typically 40,000-60,000 miles, making them one of the more frequently replaced suspension components. Road conditions and driving style affect lifespan.
Are anti-roll bar links an MOT failure?
Yes. Excessive play in the ball joints is a failure item. Knocking or play detectable by hand at the MOT station will result in a fail or advisory.
Can I drive with worn drop links?
Yes, but handling will be compromised with increased body roll. The knocking noise will worsen. Replace them for safety, comfort, and MOT compliance.
Do I need a wheel alignment after replacing drop links?
No. Anti-roll bar links do not affect wheel alignment settings. However, if the car has other suspension work pending, combining jobs with an alignment is sensible.
How much does anti-roll bar link replacement cost?
The price of anti-roll bar links depends on your exact vehicle and the brand you choose. Enter your registration above to see parts confirmed to fit, then compare prices from the brands we stock on this page. Free UK delivery on orders over £99.
