Front Axle Anti Roll Bar Lever
Sold each - 2 required per car

Restore the handling and suspension performance of your classic Porsche with this OE Match Front Axle Anti Roll Bar Lever. This precision-manufactured suspension component delivers the correct fit, strength and geometry required for reliable anti-roll bar operation.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
• Porsche 914 (1970-1976)

Diagram ref no 29

The anti roll bar lever forms a vital part of the front suspension system, transferring movement between the suspension and anti-roll bar to help minimise body roll during cornering. Replacing worn or damaged levers helps restore predictable handling, steering precision and suspension performance.

Ideal for suspension rebuilds, chassis restoration or routine maintenance, this OE Match component provides dependable quality and long service life.

What Does the Front Axle Anti Roll Bar Lever Do?

The anti roll bar lever connects the front suspension to the anti-roll bar system.

Its primary functions include:

• Transferring suspension movement to the anti-roll bar.
• Reducing body roll during cornering.
• Improving vehicle stability.
• Helping maintain balanced handling characteristics.
• Supporting more consistent tyre contact with the road surface.
• Working with the anti-roll bar to improve steering response.

A correctly functioning anti roll bar lever contributes to the precise handling characteristics for which classic Porsche models are renowned.

Why Does the Anti Roll Bar Lever Wear Out?

Over many years of use, suspension components are subjected to continual stress, vibration and environmental exposure.

Common causes of wear include:

• Corrosion from water and road salt.
• Fatigue caused by repeated suspension movement.
• Impact damage from road debris.
• Wear around mounting points.
• Distortion following suspension damage.
• General ageing after decades of service.

A worn or damaged lever can affect suspension geometry, reduce handling precision and place additional stress on surrounding suspension components.

When Should It Be Replaced?

Replacement is recommended when:

• The suspension is being rebuilt.
• The lever is bent, cracked or corroded.
• Excessive wear is visible around mounting points.
• The anti-roll bar system has excessive movement.
• Restoring the vehicle to factory specification.
• Replacing anti-roll bar bushes or related suspension components.
• Completing a concours-quality restoration.

Replacing suspension components together helps maintain correct suspension geometry and restores the handling performance of your Porsche.

Lightweight Hollow Rear Torsion Bar – Porsche 911 G50 

Transform the handling of your Porsche 911 G50 with these OE Match Lightweight Hollow Rear Torsion Bars. Engineered for enthusiasts who demand sharper handling, improved chassis balance and reduced weight, these premium torsion bars are manufactured from aircraft-grade 4130 chrome molybdenum steel and precision heat treated to deliver exceptional strength, durability and consistent spring rates.

Fits:

• Porsche 911 1987-1989 3.2L G50
• Porsche 911 1978-1989 3.3L Turbo (930)

Designed as a direct replacement for the factory rear torsion bars, these lightweight hollow bars provide the same or greater stiffness as comparable solid bars while reducing unsprung weight by up to 3lbs (1.36 kg) per bar. The result is a more responsive suspension, improved traction and greater driver confidence whether you're driving on the road, fast road or circuit.

Available in different diameters, these torsion bars allow you to tailor your Porsche's suspension to suit your driving style and performance goals.

Available Sizes

Choose the torsion bar diameter best suited to your suspension setup:

• 27mm
• 28mm
• 29mm
• 30mm
• 31mm
• 32mm

Larger diameters increase rear spring rates, improving body control and reducing chassis roll during aggressive driving.

What Do Rear Torsion Bars Do?

Rear torsion bars are the primary springing component of the classic Porsche 911 rear suspension.

They are responsible for:

• Supporting the weight of the rear of the vehicle.
• Controlling suspension movement.
• Maintaining correct ride height.
• Reducing body roll through corners.
• Improving traction and chassis stability.
• Working alongside the dampers to control suspension movement.
• Delivering the balance and handling characteristics the Porsche 911 is renowned for.

Selecting the correct torsion bar size allows the suspension to be tuned for road, fast road or motorsport applications.

Why Upgrade to Lightweight Hollow Torsion Bars?

These OE Match hollow torsion bars offer significant advantages over standard solid bars.

Benefits include:

• Up to 3 lbs (1.36 kg) lighter per bar than equivalent solid torsion bars.
• Reduced unsprung and rotational mass.
• Faster suspension response over uneven road surfaces.
• Improved steering feel and chassis balance.
• Increased cornering stability.
• More consistent suspension performance under high loads.
• Superior fatigue resistance for long service life.        

The reduction in suspension weight allows the dampers to control wheel movement more effectively, resulting in greater grip and improved ride quality.

Premium Engineering & Construction

Manufactured using premium materials and precision machining techniques, these are among the highest-quality torsion bars available.

Features include:

• Manufactured from aircraft-quality 4130 chrome molybdenum steel.
• Heat treated for maximum strength and long-term reliability.
• Hollow gun-drilled construction for reduced weight without sacrificing stiffness.
• Centreless ground to ensure consistent diameter and spring rate.
• Precision-machined splined ends for an accurate OE-style fit.
• Zinc-plated finish with plugged ends for outstanding corrosion resistance.
• Precision engineered for consistent performance and durability.        

Every component is manufactured to exacting tolerances to ensure exceptional quality and repeatable suspension performance.

When Should Rear Torsion Bars Be Upgraded?

Upgrading is recommended when:

• Improving the handling of your Porsche 911.
• Installing performance dampers.
• Lowering the vehicle.
• Rebuilding the rear suspension.
• Building a fast road or track-focused car.
• Replacing tired or corroded factory torsion bars.
• Increasing grip through wider tyres or suspension upgrades.
• Fine-tuning chassis balance for motorsport applications.

Replacing torsion bars during a suspension rebuild ensures all major wear components are renewed at the same time.
