The side sill panel end cap is a small trim piece located at the front or rear end of the rocker panel trim on classic Porsche 911 models. It covers and protects the exposed end of the sill moulding, creating a clean transition between the body panels and the rocker trim.

Theis OE Match end cap is designed to match the original Porsche design used on the G-series 911. It is installed as part of the sill trim assembly and helps maintain the authentic appearance of the vehicle’s lower bodywork.

This component is commonly replaced during body restoration, sill trim refurbishment or repair of damaged rocker mouldings.

Side sill trim components are exposed to road debris, weather and general wear. Over time the end caps can crack, fade or become damaged, leaving the sill trim unfinished and exposed. Replacing them restores the proper appearance of the rocker trim and protects the underlying bodywork.

Consider replacing the sill end cap if you notice:
•  Missing or damaged rocker trim end pieces
•  Cracked or faded plastic end caps
•  Loose sill trim components
•  During classic Porsche body restoration

Diagram Ref No 31 Or 32

Manufactured from high-quality automotive-grade material with excellent resistance to UV exposure, weathering and road debris, the end cap is precision-moulded to replicate the original Porsche design. Designed for direct OE-style installation, it integrates seamlessly with the existing side sill panel, restoring the vehicle's original appearance and ensuring a professional finish during restoration or repair. Supplied as a single part, it is suitable for replacing an individual damaged or missing end cap.

What This Product Does:
  • Finishes the exposed end of the side sill panel.
  • Protects the sill from dirt, moisture and road debris.
  • Helps prevent damage to the end of the sill assembly.
  • Restores the original appearance of the side sill.
  • Provides factory-style fitment and alignment.
  • Helps secure and complete the sill trim assembly.
  • Replaces worn, damaged or missing end caps.
  • Forms an integral part of the exterior body trim system.

Symptoms Of Wear Or Failure:
  • Missing or broken end cap.
  • Cracks or impact damage.
  • Loose or poorly fitting sill trim.
  • Faded, scratched or weathered finish.
  • Visible gaps at the end of the side sill panel.
  • Dirt and moisture collecting behind the trim.
  • Rattling or movement from the sill assembly.
  • Corrosion developing around the exposed sill area.
  • Reduced originality of the vehicle's exterior.
  • Poor cosmetic appearance during restoration.

Why Replacement Matters:

  • The side sill panel end cap is continually exposed to road debris, moisture, UV radiation and everyday wear. Over time, it can become cracked, faded or detached, leaving the end of the sill panel exposed to contaminants and reducing the finished appearance of the vehicle.
  • A damaged or missing end cap can allow water, dirt and debris to accumulate behind the sill trim, increasing the risk of corrosion while also causing the trim to become loose or vibrate. This not only affects the appearance of the vehicle but may also accelerate deterioration of surrounding bodywork and trim components.
  • Replacing a worn or damaged side sill panel end cap restores the factory appearance while helping to protect the sill assembly from environmental damage. The OE Match replacement provides OE-style fitment, durable construction and long-lasting performance, making it the ideal solution for Porsche restoration, repair and preventative maintenance.
