The rear spring plates form an important part of the Porsche torsion-bar rear suspension. They connect the rear torsion bars to the trailing-arm assembly and move as the suspension rises and falls.
Rubber bushings support each spring plate where it passes through the torsion-bar housing and spring plate cover. These bushings allow controlled rotational movement while helping keep the spring plate correctly positioned within the suspension assembly.
Over time, the original rubber can compress, harden, crack and deform. This allows the spring plate to sit off-centre, increasing unwanted suspension movement and potentially allowing metal-to-metal contact between the spring plate and its cover.
Replacing worn bushings helps restore correct spring plate support, suspension geometry, ride quality and predictable rear suspension behaviour.
What This Product Does:
The rear spring plate bushings support the spring plates within the rear torsion-bar suspension.
They are designed to:
- Support the rear spring plates.
- Keep each spring plate correctly centred.
- Allow controlled rotational suspension movement.
- Isolate vibration between suspension and body.
- Reduce metal-to-metal contact.
- Help maintain rear suspension geometry.
- Support predictable rear wheel movement.
- Reduce unwanted spring plate movement.
- Restore factory-style rubber compliance.
- Replace compressed, cracked or deteriorated original bushings.
Symptoms Of Wear Or Failure:
Possible symptoms include:
- Rear suspension squeaking.
- Creaking from the rear suspension.
- Clunking over bumps.
- Increased rear suspension movement.
- Spring plate sitting off-centre in the cover.
- Uneven gap around the spring plate cover opening.
- Spring plate contacting the cover.
- Metal-to-metal rubbing marks.
- Rear suspension feeling loose.
- Reduced stability during cornering.
- Changes in rear wheel alignment.
- Uneven rear tyre wear.
- Vehicle wandering or feeling less settled.
- Visible cracked or deteriorated rubber.
- Rubber separating from the spring plate.
- Suspension noise during acceleration or braking.
- Excessive rear suspension compliance.
Why Replacement Matters:
Replacing worn spring plate bushings helps restore:
- Correct spring plate positioning.
- Controlled suspension movement.
- Factory-style rubber compliance.
- Reduced suspension noise.
- Reduced unwanted movement.
- Improved rear suspension consistency.
- Proper clearance around the spring plate.
- More predictable handling.
- Better foundation for accurate wheel alignment.
On a classic Porsche, replacing decades-old suspension rubber can make a significant difference to how precise and settled the rear suspension feels.

Restore protection around the rear axle cross tube assembly with this OE Match Rubber Boot. Designed for compatible Porsche applications, this flexible rubber component helps protect the associated axle and suspension area from dirt, moisture, road debris and other contaminants.
Fits:
Porsche 356 (1950 to 1969)

The boot acts as a protective barrier around the relevant cross-tube connection or moving component while retaining the flexibility required for normal suspension and axle movement. Keeping this area properly protected helps reduce contamination and deterioration of the components located beneath or around the boot.
What This Product Does:
- Provides a protective covering for the associated rear axle cross tube area.
- Helps prevent dirt and road debris reaching protected components.
- Helps reduce moisture and contamination entering the assembly.
- Provides flexibility to accommodate normal suspension and axle movement.
- Helps protect associated components from premature contamination-related wear.
- Provides a barrier against everyday road grime.
- Helps maintain the condition of the rear axle and suspension assembly.
- Replaces a cracked, split, hardened, perished or missing boot.
- Helps restore a clean and complete appearance during suspension restoration.
- Provides an OE-style replacement for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Visible cracks in the rubber.
- Splits or tears in the boot.
- Rubber that has become hard or brittle.
- Perishing or surface deterioration.
- The boot no longer fitting securely in position.
- Sections of the protected assembly becoming exposed.
- Dirt or road debris accumulating beneath the boot.
- Moisture or contamination around the protected components.
- Distortion or loss of flexibility.
- Oil or chemical contamination causing the rubber to swell or soften.
- The original boot is completely missing.
- Deterioration discovered during rear suspension or axle servicing.
Why Replacement Matters:
- The rubber boot is designed to isolate vulnerable components from the harsh environment beneath the vehicle. Once the rubber cracks or splits, dirt, water and abrasive road debris can reach areas that would normally remain protected.
- Contamination can accelerate wear and corrosion of surrounding components. Dirt trapped around moving or contacting surfaces can act as an abrasive, while persistent moisture may encourage corrosion on metal parts.
- A deteriorated boot may initially appear to be only a cosmetic issue, but leaving the protected assembly exposed can contribute to more expensive component wear over time. Replacing the boot before significant contamination occurs is generally preferable to repairing damaged axle or suspension components later.
- Rubber deterioration is particularly common on classic vehicles because original components may have been subjected to decades of heating, cooling and environmental exposure. Even a boot that appears intact can become stiff and develop cracks when disturbed during servicing.

This OE Match spring plate is a direct replacement for the original Porsche rear suspension component fitted to Porsche 356 Pre-A, 356A, and 356B models. Manufactured to OE specifications, it replicates the factory closed-type design used in the classic rear torsion bar suspension system.

Installed at the rear suspension assembly, the spring plate acts as the mounting and support point for the torsion bar. It transfers suspension load from the rear axle into the torsion bar system, helping maintain proper ride height and suspension geometry. The closed-type construction provides improved rigidity, durability, and protection of the torsion bar mounting area compared to open-style versions.
The spring plate supports and positions the rear torsion bar within the suspension system. It helps maintain correct ride height, rear wheel alignment, and suspension stability while transferring load between the chassis and rear axle.
Function
• Supports rear torsion bar suspension system
• Maintains proper ride height and suspension geometry
• Transfers load between rear axle and chassis
• Helps stabilise rear suspension movement
• Provides durable mounting point for torsion bar assembly
Over time, original spring plates can suffer from corrosion, fatigue, or deformation due to decades of suspension load and environmental exposure. Worn or damaged spring plates may affect ride height, wheel alignment, and overall handling stability. Replacing the component restores suspension integrity, improves chassis stability, and helps maintain original driving characteristics.
When to replace
• Rear suspension sagging or uneven ride height
• Visible corrosion or fatigue cracks
• Excessive rear suspension movement or noise
• Suspension alignment instability
• During full suspension restoration or torsion bar servicing
