This set provides all the essential parts needed to service both stabilizer bar bushes at the front axle.
The stabilizer bar bushes (also known as anti-roll bar bushings) are rubber mounting components that secure the front stabilizer bar to the vehicle chassis. They allow controlled movement of the anti-roll bar while isolating vibration and preventing metal-to-metal contact.
The stabilizer bar bushings keep the anti-roll bar securely mounted while allowing it to twist and flex during cornering. This helps the stabilizer bar reduce body roll and maintain balanced handling.
Replacing worn bushes restores the stabilizer bar’s ability to operate effectively, improving suspension responsiveness and reducing noise from the front suspension.
Function
• Stabilizer Bar Support: Secures the anti-roll bar to the chassis
• Vibration Isolation: Rubber bushings reduce noise and vibration
• Handling Stability: Helps maintain proper suspension performance during cornering
• Durability: OE-style construction designed for long service life
Stabilizer bar bushes are subject to constant movement, road debris and environmental exposure. Over time the rubber can harden, crack or wear, leading to excessive movement of the anti-roll bar. This can cause knocking noises, reduced handling precision and increased body roll during cornering. Replacing worn bushes restores proper stabilizer bar function and improves suspension stability.
Consider replacing the stabilizer bar bush kit if you notice:
• Clunking or knocking noises from the front suspension
• Excessive body roll during cornering
• Worn or cracked rubber bushings
• During suspension servicing or stabilizer bar replacement

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.
