Porsche Left Door Seal Upper Body Mount, Coupe (74 to 85) 911-542-403-01

Restore proper weather sealing and cabin insulation with this Porsche Left Door Seal Upper Body Mount, part number 911-542-403-01, designed for Porsche 911 Coupe models from 1974 to 1985. This seal installs on the upper body channel and creates a tight barrier between the door frame and chassis.

Over time, original door seals compress, crack, or shrink due to heat and age. A worn seal can cause wind noise, water intrusion, and reduced cabin comfort. Replacing it with a correct fit upper body seal restores factory level sealing performance and helps maintain interior condition.

Manufactured to match original specifications, this left side upper door seal provides accurate contouring for coupe body style applications, ensuring consistent compression and long lasting durability.
