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.

OEMatch Spring Plate — Fit, Function, Confidence
Spring plates form a key part of the rear suspension on many Porsche models, linking torsion bars to trailing arms to control ride height, preserve alignment and manage suspension travel under load. OEMatch focuses on Porsche applications and catalogues over 4,000 part numbers and extensive cross-references to support repairs and restorations.
Understanding OEMatch Spring Plate
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original spring plate.
OE (Original Equipment) refers to parts matching original specifications for the spring plate and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM spring plate engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. In operation, a spring plate provides a pivot between torsion bar and trailing arm, helps maintain rear wheel alignment as the suspension moves, and contributes to stable ride height and handling balance. Plates are typically formed from high-strength steel or alloys and use bushes or bearings at mounting points to control movement.
Benefits Include
- Restores correct rear suspension geometry and alignment for consistent handling.
- Maintains ride height and reduces unwanted rear-end movement under load.
- Available in fixed and adjustable designs to suit restoration, service or performance use.
Why Spring Plate Wear and Fail
- Corrosion and rust that weaken the plate or mounting surfaces.
- Worn bushes or mounts producing excess play and vibration.
- Fatigue cracks from repeated torsional stress.
- Impact damage from road hazards or improper installation.
The Importance of Replacing with OEMatch Spring Plate
Replacing worn or damaged spring plates restores suspension geometry and alignment accuracy, reduces vibration and noise, and helps retain predictable handling on road and track. Proper replacement also protects related components such as trailing arms and torsion bars by removing excessive movement and restoring specified clearances, which supports safe and reliable vehicle behaviour.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances for Porsche models.
- Adjustable and performance variants available where correct ride-height or alignment tuning is required.
- Suitable for classic restorations, routine servicing and track-focused preparations.
