What This Product Does:
- Holding the torsion bar end and anchoring it to the chassis or suspension structure.
- Providing a mounting surface for the torsion bar to twist against, effectively managing the rear spring action (torsional stiffness).
- The adjustable aspect allows you to change preload, camber, or ride height for tuning the rear suspension setup to your desired performance balance (road or track)
- Helping maintain correct geometry as suspension moves, ensuring better tire contact, handling, and responsiveness.
- Rust / corrosion / fatigue: The old plates may be rusty or weakened, especially in classic cars.
- Sagging or misalignment: Rear ride height may fall, or camber might drift under load.
- Uneven tire wear: Because geometry is off or not held firmly, the tires may wear more on one edge.
- Poor rear handling / unpredictable grip: The rear may feel loose under cornering or shift unpredictably under load.
- Difficulty setting or maintaining geometry: Without adjustability, it’s harder to dial in suspension tweaks, especially for track use or changed setups (wider tires, stiffer suspension, etc.).
Factory spring plates offer limited adjustment. This RS-style sports version allows quick and accurate tuning of ride height, preload, and camber, giving sharper handling and better tire contact for both road and track.

Rubber Boot For Real Axle Cross Tube.
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)
Diagram Ref No 4
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.

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)
Diagram Ref No 4
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.
