Upgrade the front roll control of your classic Porsche 911 with this adjustable 19 mm front anti-roll bar kit. Designed for 1965-73 911 models, this kit replaces the standard 15 mm bar with a stiffer 19 mm unit, and includes adjustable levers/drop-links to fine-tune roll stiffness. Whether you’re restoring a vintage 911 or upgrading for performance, this kit offers improved cornering stability, sharper front-end response and tuning flexibility.
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:
- An anti-roll bar (sway bar) connects the left and right sides of the front suspension to resist body roll during cornering. It transfers load between the two sides so the outside wheel shares part of the load with the inside one, reducing lean.
- By increasing the diameter from 15 mm to 19 mm, the bar becomes stiffer, thus reducing body roll further and improving cornering stability and front-end responsiveness.
- The “adjustable” aspect of the kit allows the driver or technician to change the lever arm length or link pivot point to vary roll stiffness—so you can fine-tune how much the bar contributes vs the springs.
- This kind of upgrade improves chassis balance, driver feedback, quicker turn-in, and reduced dynamic body lean — especially beneficial on vintage sports cars like the 911 when driven spiritedly or on track.
Symptoms & Signs You Might Need This:
- You feel excessive body roll at the front during cornering, or the front end feels soft or unstable in lateral transitions.
- The handling is less sharp than you expect, especially if the suspension has been upgraded (lowered, stiffer springs) and the standard sway bar is now the weak link.
- You’ve installed wider or stickier tyres, or uprated front suspension components, and want the front anti-roll bar to match the rest of the setup.
- You want to tune or adjust the balance between understeer/oversteer – using an adjustable bar lets you adapt front roll stiffness.
- You’re restoring a vintage 911 and want a strong, performance-capable bar with correct style and function.
Why Replacement / Upgrade Matters:
- A stock sway bar may become inadequate when other suspension elements get upgraded — lowering, heavier wheels, larger tyres all increase demands on the bar. Upgrading to the 19 mm adjustable kit ensures the front links are not the limiting factor.
- Improved roll stiffness means the car behaves more consistently under load — less lean, more predictable weight transfer, better driver confidence.
- The adjustable kit gives you tuning flexibility — you can adapt the stiffness for road vs track, or change the balance if you alter tyres, springs, or other suspension components.
- In a vintage car, a properly specified upgrade also helps maintain or enhance value — strong handling and correct appearance matter.
- Finally, a performance upgrade like this supports safer driving dynamics when pushing the car harder.

Adjustable Drop Links
The ideal sway bar (anti roll bar) is completely unloaded at static ride height. Stock drop links almost always preload the sway bar since the car doesn't sit perfectly level due to asymmetries such as driver weight. Our front and rear adjustable-length drop links for C4/C2 allow you to eliminate preload of the sway bar for maximum performance.
A preloaded sway bar shifts the weight carried by each of the tyres, increasing grip on weighted ones at the expense of decreasing grip on un-weighted ones. This shifted weight/grip causes uneven handling in left and right turns, and premature brake lockup since the less-loaded tyre locks up first. Preload can be completely eliminated by adjusting drop link length and sway bar performance optimized.

Information
Lateral support clamp anti roll bar.
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.
