Rear Shock Absorber Bump Stop Spring. 
The OE Match Rear Shock Absorber Bump Stop Spring is a high-quality replacement suspension component designed to provide progressive cushioning and protection for the rear shock absorber assembly during maximum suspension compression. Manufactured to OE specifications for fit, performance and durability, this bump stop spring helps prevent harsh bottoming-out while protecting critical suspension components from excessive impact loads.

Diagram Ref No 4

Installed as part of the rear suspension and shock absorber assembly, the bump stop spring acts as a secondary spring element that progressively absorbs energy as the suspension approaches the end of its travel. Constructed from durable, high-density elastomer or microcellular material, it is engineered to withstand repeated compression cycles, heavy loads and demanding road conditions.  

What This Product Does:
  • Limits rear suspension travel during extreme compression.
  • Provides progressive cushioning at the end of suspension travel.
  • Protects the rear shock absorber from bottoming out.
  • Reduces impact loads transmitted to the chassis.
  • Helps maintain ride comfort over uneven road surfaces.
  • Supports suspension stability under heavy loads.
  • Protects suspension mounts and associated components from damage.
  • Contributes to overall suspension durability and performance.

Symptoms Of Wear Or Failure:
  • Harsh impacts felt from the rear suspension.
  • Suspension bottoming out over bumps or under load.
  • Knocking, thumping or banging noises from the rear suspension.
  • Reduced ride comfort.Excessive suspension travel.
  • Cracked, split or crumbling bump stop material.
  • Visible deterioration or compression of the bump stop.
  • Increased wear on rear shock absorbers and mounts.
  • Reduced suspension control during heavy loading or spirited driving.

Why Replacement Matters:

  • Rear bump stop springs are subjected to continual compression, vibration, moisture, road debris and temperature fluctuations throughout their service life. Over time, the material can harden, deteriorate, crack or lose its ability to absorb impact energy effectively.
  • A worn or damaged bump stop spring can allow the suspension to reach the end of its travel without adequate cushioning, placing excessive stress on the shock absorbers, suspension mounts and chassis structure. This can result in reduced ride quality, accelerated suspension wear and potentially costly repairs to associated components.
  • Replacing a worn rear shock absorber bump stop spring restores proper suspension protection, improves ride comfort and helps maintain the intended performance of the rear suspension system. An OE Match replacement provides factory-style fitment, reliable impact absorption and long-term durability, ensuring your Porsche continues to deliver the comfort, stability and handling characteristics expected from its suspension design.
