This OE-Match tension spring is a high-quality replacement that replicates the original factory spring used in the seat adjuster and tensioning mechanism of classic Porsche 356.

This spring maintains the proper tension in the seat adjuster system, ensuring that the seat slides and locks smoothly and holds securely in place. It helps prevent the seat from drifting or loosening under load.
Over time, the original spring may weaken, corrode, or lose tension, causing loose movement, poor locking, or rattling in the seat mechanism. Replacing it with a new OE-Match spring restores firm tension, stability, and smooth, precise seat adjustment.

Porsche Seat Parts | Design911 Components for Repair, Adjustment & Restoration
Seat parts are essential to maintaining the comfort, support, and functionality of your Porsche’s interior. Every element — from hinges and sliders to adjustment mechanisms and mounting hardware — plays a key role in providing a secure, ergonomic driving position. Whether you’re restoring a classic Porsche or maintaining a modern performance model, ensuring that all seat components operate smoothly is vital for safety, comfort, and overall driving experience.
At Design911, we supply an extensive range of seat parts and components, including runners, rails, recliner mechanisms, hinges, adjustment handles, brackets, and seat mounts. Each part is designed for accurate fitment, long-term durability, and precise operation. Ideal for interior restorations, seat repairs, or upgrades, our components are crafted from premium materials to maintain Porsche-level comfort and performance.
What Do Seat Parts Do?
Seat parts ensure stability, comfort, and adjustability, providing the perfect driving position while maintaining occupant safety.
Core Functions:
• Enable fore/aft, height, and recline adjustments for comfort and control.
• Secure the seat frame to the chassis for stability and safety.
• Allow smooth sliding and locking through precision-engineered rails.
• Support seat back and cushion structure under load.
• Ensure ergonomic posture for both everyday and performance driving.
Every part contributes to the seamless operation of your seat — ensuring your Porsche’s driving feel remains precise and comfortable.
Why Do Seat Parts Fail or Degrade?
Seat mechanisms and structural components are exposed to constant stress, movement, and environmental factors that can lead to wear or malfunction.
Common Causes of Failure Include:
• Metal fatigue or corrosion from moisture or use over time.
• Worn sliders or seized adjustment rails.
• Damaged recliner mechanisms or broken levers.
• Cracked plastic trims or deteriorated bushings.
• Loose or misaligned mounting hardware.
When seat parts fail, movement, noise, or misalignment can occur — compromising comfort, safety, and driving precision.
