Car Roof Side Rails Types

Car roof side rails are structural components that are mounted on the roof of a vehicle to provide attachment points for various accessories such as roof racks, cargo boxes, and bike carriers. They also add a sporty or rugged look to the vehicle. There are several types of car roof side rails:

1. Raised Side Rails: These are the most common type of roof rails found on many modern SUVs and crossovers. They are raised off the roof of the vehicle and run from the front to the rear, parallel to each other. Raised side rails provide a sturdy base for attaching roof racks and other accessories.

2. Flush or Integrated Side Rails: Some vehicles have flush or integrated side rails that are almost level with the roof. They are designed to blend seamlessly with the vehicle's roofline, providing a sleeker appearance. While they may not be as versatile as raised side rails, they can still be used for mounting certain accessories.

3. Factory vs. Aftermarket Rails: Factory roof rails are installed by the manufacturer during production and are typically sturdier and more integrated into the vehicle's design. Aftermarket roof rails, on the other hand, can be added to a vehicle after purchase. While aftermarket options may be more affordable, they might not offer the same level of integration and strength as factory-installed rails.

4. Crossbars: Crossbars are not exactly side rails, but they are often used in conjunction with them. Crossbars are the horizontal bars that connect to the side rails, forming a foundation for roof-mounted accessories. They can be removable or fixed, and their spacing and design can vary depending on the vehicle's make and model.

5. Aero Bars: Aero bars are a type of crossbar designed with aerodynamics in mind. They are typically more streamlined and can reduce wind noise and improve fuel efficiency compared to traditional square or round crossbars.

6. Adjustable Rails: Some vehicles come with adjustable side rails that can be moved along the length of the roof to accommodate different types of cargo or accessories. This adjustability can be convenient for users who frequently change their roof-mounted equipment.

7. Panoramic Roof Rails: In some luxury vehicles, panoramic roof rails are integrated into the sunroof system, providing a seamless and stylish look. These rails may not be as functional for attaching accessories due to their design.

8. Fixed vs. Removable Rails: Some roof rails are fixed and cannot be removed, while others are removable, allowing you to take them off when not in use. Removable rails are useful if you prefer the cleaner look of your vehicle without roof rails when you're not using them.

9. Raised vs. Recessed Mounting Points: Depending on the design of the side rails, the mounting points for accessories may be raised above the rail's surface or recessed within it. This can affect how accessories are attached and their overall profile on the roof.

The type of roof side rails on a specific vehicle will depend on the make and model, as well as the trim level and options chosen by the owner. It's essential to understand the type of roof rails your vehicle has to determine which accessories can be safely and securely attached to them.
