The Left door foam lining is a sound‑absorbing pad that fits inside the driver‑side door cavity. This Door Accessories component reduces road noise and improves cabin acoustics, providing a quieter ride. Its precision‑cut shape ensures a perfect fit against the door panel, and the high‑density foam resists moisture and deformation over time. Installation is quick and tool‑less, making this Door Accessories part a practical upgrade for any Sitrak C7H.
The Right door foam lining is the mirror‑image counterpart, providing identical acoustic benefits for the passenger side. This Door Accessories component ensures balanced noise reduction across the cab, enhancing overall driving comfort. Like the left version, it is made from durable, moisture‑resistant foam and fits securely into the door cavity. Installing both linings doubles the effect, making this Door Accessories kit a valuable addition for long‑haul drivers.
The Right door door control switch is a durable electrical component that detects the door open/close status. This Door Accessories part is mounted on the passenger side and sends a signal to the cab’s electronic system, activating interior lights and warning indicators. Its sealed design resists moisture and dust, ensuring reliable operation in all weather conditions.

The Door outer sealing strip is a flexible rubber profile that seals the gap between the door and the cab frame. This Door Accessories component prevents water, dust, and wind noise from entering the cabin, maintaining a clean and quiet interior. Its hollow bulb design compresses evenly when the door is closed, creating a tight seal. Easy to install with a self‑adhesive backing, this Door Accessories part is essential for preserving the cab’s climate control.
The Door outer sealing strip II is a secondary sealing element that provides additional protection against the elements. This Door Accessories part is installed on the lower section of the door, reinforcing the primary seal. It is made from the same high‑quality EPDM rubber and features a similar self‑adhesive backing. Together with the primary strip, this Door Accessories component ensures maximum sealing efficiency, reducing road noise and preventing water ingress during heavy rain.
The Plastic nut seat (ST4.8) is a threaded insert that provides a strong anchor point for screws in plastic panels. This Door Accessories fastener is pushed into a pre‑drilled hole and locks in place, offering a durable thread for repeated assembly and disassembly. It is made from nylon with a zinc‑plated steel nut, combining strength and corrosion resistance. These nut seats are essential for securing the trim panels and switches, preventing loosening over time. This Door Accessories component is supplied in the required quantity for the entire kit.
The Passenger side door controller is an advanced electronic unit that manages the door’s electric functions, including window lift and central locking. This Door Accessories component is designed for the high‑configuration cab, supporting auxiliary switches for additional features.

Upgrading to this genuine Door Accessories part enhances the passenger side’s convenience and control.
The Left door door control switch is the driver‑side counterpart of the right switch, providing the same door‑status detection. This Door Accessories part is essential for activating the cab’s interior lighting and warning systems. Its robust construction and sealed contacts guarantee long‑term reliability, even in demanding environments. Replacing a worn switch with this genuine Door Accessories component ensures accurate door indication and enhances overall safety.
The Controller + remote control is a comprehensive set that includes a central door control unit and a wireless remote.

This assembly combines a cross recessed pan head screw with a flat washer. It is used for securing various trim components and switches of The part kit. The screw is made from corrosion‑resistant steel, and the washer distributes the load evenly to prevent damage to the plastic parts. Its cross recess allows for easy driving with a standard screwdriver. This Door Accessories fastener is supplied in the correct length for the specific mounting points, ensuring a secure and lasting hold.
This assembly consists of a cross recessed pan head screw, a spring washer, and a flat washer. It is used for heavy‑duty fastening of the door controllers and brackets within The part kit. The spring washer prevents loosening under vibration, while the flat washer distributes the load. The screw is made from high‑tensile steel with a zinc finish. This Door Accessories fastener is ideal for securing components that are subject to constant movement and shock.
