Titanium Rear Anti-Roll Bar Kit
Upgrade the rear suspension performance of your classic Porsche 911 with this lightweight Titanium Rear Anti-Roll Bar Kit, engineered specifically for long wheel base Porsche 911 models up to 1989.
Manufactured from aerospace-grade titanium, this advanced rear anti-roll bar system is designed to reduce weight, improve chassis balance, and enhance rear-end stability during spirited road driving and motorsport use.
Fits:
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
- Porsche 911 1978-1983 3.0L / SC
- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50
- Porsche 911 1975-1977 3.0L Turbo (930)
- Porsche 911 1978-1989 3.3L Turbo (930)
Kit Contents
• 1 x titanium rear anti-roll bar
• 2 x rear anti-roll bar lever arms
• 2 x rear anti-roll bar bushes
• 2 x rear anti-roll bar mounting brackets
• 2 x rear anti-roll bar drop-links
The titanium rear anti-roll bar measures 22mm and delivers a stiffness rating equivalent to a solid 18mm bar, providing improved body control and sharper handling characteristics while maintaining lightweight performance benefits.
To further optimise suspension efficiency, the anti-roll bar lever arms have been completely redesigned and precision-manufactured from lightweight aluminium using topological optimisation techniques. This process maximises rigidity and strength while significantly reducing overall component weight.
Compared to factory steel suspension components, this kit delivers substantial reductions in unsprung and rotational mass, improving suspension response, steering precision, and overall chassis dynamics.
Ideal for lightweight restorations, fast road builds, and track-focused Porsche 911 projects.

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.
