- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
Upgrade the front roll control of your classic Porsche 911 with this high-performance adjustable 22 mm front anti-roll bar kit. Specifically designed for 1965-73 911 models, this kit replaces the original 15 mm bar with a larger diameter 22 mm unit and includes adjustable drop-links/levers for fine-tuning roll stiffness. Whether you’re restoring a vintage 911, upgrading for spirited driving or prepping for track use, this kit enhances cornering stability, improves front-end responsiveness and allows tuning to match your suspension setup.
Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
What This Product Does:
- The front anti-roll bar connects the left and right front suspension arms, limiting body roll by transferring load from the outside wheel to the inside wheel during cornering.
- A larger diameter bar (22 mm vs 15 mm) increases torsional stiffness, reducing body lean, improving turn-in and chassis stability.
- The “adjustable” aspect adds the ability to change the lever arm or drop-link position, allowing fine-tuning of roll stiffness (e.g., softer for street, stiffer for track) without changing the bar itself.
- As a result you get sharper front-end response, flatter corners, improved tyre contact and more confidence in dynamic driving.
Symptoms & Signs You Might Need This Upgrade:
- Excessive body roll or lean in the front end during cornering, or a feeling that the car “leans” more than it used to.
- The front suspension feels less sharp, turn-in feels delayed or vague — especially if you’ve already upgraded springs, shocks or tyres and the bar is now the limiting factor.
- If your car has been lowered, fitted with wider tyres, stiffer suspension, or is used for track, the factory bar may no longer provide adequate control.
- You want to tune or adjust your front roll stiffness — the adjustable kit gives you that capability.
- Visible signs: a thinner or corroded stock front bar, worn drop-links, excessive movement in the front roll bar mount bushes etc.
Why This Upgrade Matters:
- By increasing front anti-roll stiffness, you improve the car’s dynamic behaviour: better balance, less front body-roll, sharper front-end response, and improved driver confidence.
- The adjustable feature gives real world flexibility: you can match stiffness to your tyres, springs, driving style or track/road use rather than being locked into factory spec.
- For a classic 911 used in sporty driving, cautious track use or performance upgrades, this bar upgrade supports the rest of the suspension system rather than being the weak link.
- If you leave the stock bar while upgrading other components, you risk handling being compromised — upgrading ensures all parts rise together.
- Finally, from a restoration perspective, fitting a well-specified upgrade enhances the value and usability of the car.

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.
