Product Information

Adjustable 19mm Front Anti Roll Bar Kit.
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.
