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 function and rear axle stability.

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.

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.
