Wabco 1811130030 Side Skirt

Description

The Wabco 1811130030 Mid Skirt is a component used within trailer brake controls and air brake systems. It's designed for mounting on the left side and provides easy access to control devices. This skirt features a cut at the bottom and increased clearance at the axles exceeding 50mm. It adheres to OE specifications, ensuring reliable performance and durability within the air brake system.

Key Features & Benefits

These are primarily for aerodynamic improvements. They basically fill in the space between the trailer and the truck’s tires. They reduce turbulence and drag. Some designs also help with spray suppression, keeping road grime from getting up onto the trailer or other vehicles. They aren't directly a braking component even though you find them listed with brake controls, it’s more about overall trailer efficiency. Think of it like this: without a side skirt, air is rushing around and under the trailer, creating a lot of resistance. The skirt smooths out the airflow, kind of like giving the trailer a more streamlined shape. It’s attached to the side of the trailer, running along the length between the tires. They aren't load bearing, so they don’t affect the trailer's suspension or weight capacity, just how it moves through the air.

Symptoms, Risks & Replacements

The biggest thing is fuel savings. Reducing drag means the truck doesn't have to work as hard to maintain speed, which translates into better gas mileage. You'll notice if one gets damaged or falls off, because you’ll feel a slight decrease in efficiency and maybe a little more spray from the road. They also help with stability, especially in crosswinds. You can find a good selection of these at places like Fixparts Online, and they have different styles depending on your trailer’s needs. They're not critical for operation, the trailer will still roll without it, but it’s definitely a component that helps with performance and saves you money in the long run.
