Plastic running boards stand out with their lightness and affordable cost, but their durability may not be as high as metal. Carbon fiber running boards are popular in sports vehicles and among tuning enthusiasts, because this material contributes to both lightweight and aerodynamic performance. There are also models with different functionality, such as LED illuminated or specially coated running boards.

Running Sill Models

Running sill models vary according to the design of the vehicle and aesthetic preferences. Original factory models fully comply with the overall design of the vehicle, while modified rocker models offer a more sporty and aggressive appearance. Side step running boards are preferred in SUVs and pick-up vehicles for both their aesthetic and functional features, because they make it easier to get into the vehicle. Extended running boards are used to increase aerodynamics and are common on performance-oriented vehicles. Each model offers different options according to both aesthetic and functional needs.

Running Board Prices

Running board prices may vary in a wide range depending on the vehicle's brand, model, type of material used and the design of the rocker panel. Basic running boards produced for standard vehicles are more affordable and come in options made of plastic or sheet metal. However, sports or off-road running boards that offer high durability and are made of lighter and stronger materials such as aluminum or carbon fiber can be sold at higher prices. In addition, specially designed or extended running boards offer aesthetic and aerodynamic advantages for modified vehicles, so the prices of the running boards may also increase. Installation costs are also added to the running board prices, which may increase the total cost. Therefore, when choosing a running board, it is important to consider the long-term durability and performance expectations, as well as the intended use of the vehicle, budget and aesthetic preferences.

Functions of the running board

1. Body Durability: The running board is a component that strengthens the sides of the vehicle and supports its general structural integrity. These parts prevent the body from bending or being damaged in the event of a vehicle collision or in difficult road conditions. The running board is produced from thicker and stronger materials to increase the durability of the vehicle, especially in off-road vehicles and SUVs.

2. Pedestrian Safety: In the event of a collision with a pedestrian, the running board can reduce the risk of injury by absorbing the impact at the bottom of the vehicle. For this reason, the sill design in modern vehicles has been optimized to increase pedestrian safety.

3. Aesthetic Contribution: The sill also plays an important role in terms of aesthetics by beautifying the side profile of the vehicle. Especially in sports cars, side sills combine with aerodynamic designs to give the vehicle a more dynamic appearance. In some modified vehicles, the running boards are enlarged or different materials are used to give the vehicle a more aggressive appearance.

4. Protection: The running boards protect the lower parts of the vehicle from road debris, mud, water and other external factors. Especially in winter, road salt and stones can damage the underside of the vehicle. By minimizing such damages, running boards help protect the infrastructure of the vehicle.

Running Board Types

Running boards are designed in different ways depending on the vehicle type and purpose of use. Here are some commonly used types of running boards:

1. Stock Running Boards: These running boards are installed at the factory by the vehicle manufacturers and adapt to the general structure of the vehicle. It is produced simply and in accordance with the original design of the vehicle.

2. Sports running boards: Used in sports cars or modified vehicles, these types of running boards attract attention with their aerodynamic features. Wider and closer designs provide the vehicle with a more dynamic and sporty appearance.

3. Off-Road Running Boards: These running boards, specially designed for off-road vehicles and SUVs, are produced from thicker and more durable materials. Off-road running boards are ideal for protecting the body and infrastructure of the vehicle in difficult road conditions.
