It is a wide type decorative sill panel with a rubber insert that was fitted to the long wheelbase Porsche 911 from 1969 through 1973. The moulding is sized to approximately 59.5″ long and fits either left or right side of the vehicle. This exterior body-trim part sits along the lower rocker (side sill) area below the doors

The side sill moulding serves both aesthetic and protective roles on the vehicle’s lower bodywork:
• Protects the rocker panel from minor impacts, road debris, and scrapes
• Accentuates the classic body line, contributing to the vehicle’s period-correct look
• The rubber seal helps bridge the gap between the trim and body, reducing moisture ingress behind the moulding and offering a more finished appearance
• Helps maintain authentic exterior style on restored or well-maintained classic vehicles.
Over decades on the road, original sill mouldings and seals can:
• Fade, crack, or warp
• Lose adhesion or proper fit
• Expose underlying rocker panels to corrosion or damage.
Replacing worn or missing sill trim restores the correct visual line and offers renewed protection for the lower bodywork - especially important on restored vehicles or those being prepared for show-quality presentation.
Replace this side sill moulding if:
• The original trim is missing, cracked, split, or faded
• Rubber insert has hardened or detached
• Re-assembling after bodywork or repaint
• During a body restoration or concours detailing project

OEMatch Side Sill Seals — Fit, Finish, Clarity
Side sill seals form a protective barrier along the door threshold and lower body, keeping water, grit and road debris away from the sill cavity and cabin. OEMatch supplies a selection of rubber sill seals for Porsche models suitable for restoration, repair and routine maintenance.
Available Types- Extruded EPDM profiles for continuous sill runs
- Pre-formed sill weatherstrips shaped for specific model contours
- Adhesive-backed edge seals and trim pieces for local repair
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original side sill seals.
OE (Original Equipment) refers to parts matching original specifications for the side sill seals and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM side sill seals engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Fitted along the sill flange and door threshold, these seals block moisture and contaminants, limit wind noise and support door sealing. Correct material resistance, section profile and secure attachment are important for lasting performance.
- Prevents water ingress and sill cavity corrosion
- Reduces wind noise and vibration at the door threshold
- Protects paint edges and interior trim from grit and moisture
- Supports consistent door sealing and cabin comfort
- Prolonged UV and ozone exposure causing hardening or cracking
- Repeated compression from door closing leading to fatigue
- Abrasion from trapped dirt and road debris
- Misalignment, damaged mounting channels or corroded sill flange reducing contact
Replacing degraded sill seals reduces the risk of water entering the bodywork and helps prevent corrosion that can spread to structural areas. New seals restore acoustic insulation and maintain door fit and weatherproofing, contributing to long-term preservation of Porsche body panels.
Advantages- Made from weather-resistant rubber compounds such as EPDM
- Retains flexibility and sealing contact across normal temperature ranges
- Available in pre-formed and extruded profiles to suit specific model contours
Fitting can appear straightforward but may require specific procedures such as correct positioning, sealing detail and careful reassembly to avoid panel damage. If you lack the right tools or experience, or if the vehicle includes hidden fasteners or sensors, seek professional installation. Recheck fasteners and seal compression after initial use.
