The front anti-roll bar connects across the front suspension and helps reduce body roll during cornering. By transferring suspension load between the left and right front wheels, it supports more stable handling, improved road feel, and predictable front axle control.

Functions
•  Replaces the front anti-roll bar / stabiliser bar
•  15 mm diameter specification
•  Helps reduce front body roll during cornering
•  Supports stable and predictable handling
•  Helps maintain correct front suspension behaviour
•  Replaces bent, corroded, worn, damaged, or missing original anti-roll bars
•  OE Match replacement for classic Porsche suspension repair and restoration.

Why Replace This Part?
Front anti-roll bars can become corroded, bent, worn at the mounting areas, damaged by impact, or affected by previous suspension repairs. A worn or damaged anti-roll bar may cause poor handling, excessive body roll, knocking noises, uneven suspension response, or incorrect suspension geometry. Replacing the bar helps restore correct front suspension stability and OE-style handling characteristics.

When to Replace This Part
•  The front anti-roll bar is bent, rusty, damaged, or missing
•  Excessive body roll is felt during cornering
•  Knocking or movement is present around the anti-roll bar mounts
•  The front suspension is being rebuilt or restored
•  Anti-roll bar bushes, drop links, or mounting hardware are being replaced
•  Incorrect or non-original anti-roll bar parts have been fitted
•  The vehicle is undergoing Porsche 911 or 914 suspension restoration.

Where it fits on the car
This anti-roll bar fits across the front suspension assembly on Porsche 911 and 914 models. It works with the relevant front anti-roll bar bushes, links, and mounting hardware according to the factory suspension layout.

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.
