Torsion bar rubber mount, Front.
SET OF 2.
OE Match replacement — engineered to the same specifications as the original Porsche part. This rubber mount (or bushing) supports the front torsion (stabiliser) bar by clamping around it and anchoring it to the chassis.

Fits:
Porsche 911S 1965-67
Porsche 911S 1968 USA
Porsche 911S 1969
Porsche 911S / Carrera 2.7L / 911T/E / 911T-K 1970-73
Porsche 914 1970-76

Diagram Ref No 23

Torsion bar rubber mount isolates the torsion bar from direct metal-to-metal contact, reducing vibration, noise, and wear. The mount allows controlled movement of the bar while ensuring the suspension geometry and roll control forces are correctly applied. It helps maintain proper chassis stiffness and ensures smooth, consistent handling.

Why replacement matters:
Over time, the rubber in the mount degrades due to heat, age, compression, and dynamic loads. Cracks, flattening, or deterioration of material is common in older cars.
 A worn mount allows excessive play, leading to clunks, squeaks, imperfect roll control, or erratic handling.
 It can transmit unwanted vibration into the chassis or cabin when the torsion bar flexes under loads.
 Replacing with a high-quality OE-Match part restores the original precision, reducing noise and restoring proper suspension behaviour.
 Because these mounts support the torsion bar’s leverage on the chassis, a failure or poorly fitting mount can compromise handling stability.

Be sure to confirm the bar diameter to match the correct mount size.

About Torsion Bar

Porsche Torsion Bars | Design911 Suspension Components for Ride Height, Balance & Handling Precision

Torsion bars are an integral part of Porsche’s classic suspension design, providing spring resistance that supports the vehicle’s weight and absorbs road irregularities. Acting as the main spring element, they twist under load to control suspension movement and maintain ride height. Properly functioning torsion bars ensure balanced handling, consistent alignment, and the smooth, composed driving feel that defines Porsche engineering.

At Design911, we offer a wide range of torsion bars for both front and rear suspension setups. Each component is precision-engineered from high-tensile spring steel or performance-grade materials to provide durability, accuracy, and consistent performance. Whether for restoration, suspension servicing, or performance tuning, our torsion bars help restore and enhance your Porsche’s suspension dynamics.

What Do Torsion Bars Do?

Torsion bars act as load-bearing springs within the suspension system. When the wheels move up and down, the bars twist along their axis to absorb impact and maintain control.

Core Functions:
• Provide spring resistance to support vehicle weight.
• Maintain correct ride height and chassis balance.
• Control suspension compression and rebound during driving.
• Distribute load evenly for predictable handling.
• Enable fine-tuning of suspension stiffness and ride comfort.

With well-calibrated torsion bars, your Porsche delivers improved grip, stability, and cornering precision — both on the road and track.

Why Do Torsion Bars Fail or Degrade?

Over time, torsion bars endure extreme twisting forces, environmental exposure, and wear, which can reduce their effectiveness and strength.

Common Causes of Failure Include:
• Metal fatigue from repeated flexing and torsional stress.
• Corrosion or pitting weakening the bar’s surface.
• Cracks developing from overloading or impact.
• Incorrect ride height adjustments causing uneven stress.
• Aging bushings and mounts reducing alignment accuracy.

When torsion bars wear or crack, symptoms include uneven ride height, unstable handling, and unpredictable suspension response — all clear signs replacement is required.

Why Replace or Upgrade Your Porsche Torsion Bars?

Replacing tired or damaged torsion bars restores suspension strength, ride height accuracy, and overall handling precision. Performance torsion bars can also improve chassis stiffness for track use or spirited driving.

Key Benefits:
• Restores proper suspension balance and ride height.
• Improves cornering stability and handling predictability.
• Reduces body roll and uneven weight distribution.
• Available in standard and performance-rated diameters.
• Fits Porsche 911, 912, 914, 924, 944, and classic models.
• Perfect for restorations, tuning, or performance upgrades.

Design911’s Porsche torsion bars combine superior material quality with exact fitment — ensuring your suspension remains stable, balanced, and ready for precision driving.

Highlights

• Premium Porsche torsion bars and suspension components.
• Precision-machined from high-tensile spring steel.
• Restores suspension stiffness, balance, and ride height.
• Available in road, sport, or track specifications.
• Compatible with classic and performance Porsche models.
• Ideal for restoration, maintenance, or suspension tuning.
