Cross bars, essential for anyone looking to maximize their vehicle’s cargo capacity, come in various types, each tailored to specific needs and vehicle designs. Understanding the differences can help you select the best option for your car and your cargo.
Factory Cross Bars
Factory cross bars are designed and manufactured by the same company that makes the vehicle. They are often preferred for their seamless integration with the car’s design, ensuring a snug fit without the need for additional adjustments. These cross bars usually have a lower profile and are less likely to cause wind noise, though this can vary by vehicle model. For example, some users have noted that factory cross bars on models like the Mazda CX-50 can lead to noticeable wind noise, which can be mitigated with specific inserts or by opting for different aftermarket options.
Pros:
- Perfect fit: These cross bars are tailored to the vehicle, ensuring a snug and secure fit.
- Aesthetic appeal: They match the design of the car, maintaining the vehicle’s streamlined look.
- Ease of installation: Typically easier to install since they are designed for the specific model.
Cons:
- Limited versatility: They might not be compatible with all aftermarket accessories.
- Cost: Factory-installed cross bars can be more expensive than aftermarket options.
Aftermarket Cross Bars
Aftermarket cross bars are made by third-party manufacturers and are often favored for their versatility and extensive range of options. Brands like Thule and Yakima dominate this market, offering products that fit a wide variety of vehicles and cargo needs. These cross bars are praised for their durability and the flexibility to use various accessories. However, they can be more expensive and might require more time to install correctly. For instance, some users have highlighted the advantage of aftermarket cross bars’ ability to hold more weight and provide more width, which is ideal for carrying larger items like kayaks.
Pros:
- Versatility: Compatible with a variety of accessories, providing more options for carrying different types of gear.
- Variety: Available in different materials and designs, including aerodynamic models that reduce wind noise.
- Cost: Can be more affordable than factory-installed options.
Cons:
- Fit: May require additional fittings to secure properly.
- Installation: Can be more complex to install compared to factory-installed options.
Raised Rail Cross Bars
Raised rail cross bars attach to the existing rails on a vehicle’s roof. They are popular for their ease of installation and the ability to provide a sturdy base for carrying loads. These bars are often more versatile in terms of what they can carry and are preferred by those who need to frequently change their cargo setups. Users have reported that models like the Yakima RailBar provide excellent stability and can handle a variety of cargo types, including heavier items like rooftop tents and large cargo boxes.
Flush Rail Cross Bars
Flush rail cross bars are designed for vehicles with flush-mounted rails. These bars often provide a sleek look and can be more aerodynamic than other types, reducing wind resistance and noise. However, they may not offer the same level of cargo flexibility as raised rail cross bars. Some users find that while these bars are aesthetically pleasing, they might need additional accessories to fully utilize their cargo-carrying potential.
Aero Bars
Aero bars are designed with aerodynamics in mind. Their streamlined shape reduces drag and wind noise, making them a preferred choice for those who drive long distances or at higher speeds. These bars often come with additional features like T-channels for easy mounting of accessories. Reviews have indicated that aero bars, such as those offered by Thule and Yakima, provide a good balance of noise reduction and load-carrying capability.
Pros:
- Reduced noise: Their shape helps in cutting down the noise produced by wind.
- Improved fuel efficiency: Lower wind resistance can slightly improve fuel efficiency.
- Sleek design: They tend to look more modern and integrate better with the vehicle’s aesthetics.
Cons:
- Cost: Generally more expensive than standard rectangular cross bars.
- Compatibility: May not fit all roof rack accessories, especially those designed for square or round bars.
Square and Round Bars
Square and round bars are among the most traditional types of cross bars. Square bars are known for their durability and the ability to provide a strong grip for various mounts and accessories. Round bars, while also strong, offer more flexibility in terms of mounting different types of accessories. However, both types can cause more wind noise compared to the more modern aero designs. Users have pointed out that while these bars are reliable, they may require additional wind noise reduction solutions like fairings or wraps.
Pros:
- Strength: Capable of carrying heavy loads, making them ideal for larger items like canoes and heavy cargo boxes.
- Compatibility: Many accessories are designed to fit square and round bars.
- Cost: Often less expensive than aerodynamic models.
Cons:
- Noise: Can produce more wind noise compared to aerodynamic models.
- Aesthetics: May not look as sleek as factory-installed or aerodynamic cross bars.
Integrated Cross Bars
Integrated cross bars combine the cross bar and the mounting foot into a single unit. This design is often found in factory-installed setups and is appreciated for its clean look and ease of use. However, these bars might not be as versatile in terms of accessory compatibility and may have lower weight capacities compared to other types. They are often preferred for their simplicity and the reduced need for additional parts.
Recommendations and Considerations
When choosing cross bars, consider your vehicle’s design, the type of cargo you plan to carry, and your budget. Factory cross bars are excellent for ease of use and integration, while aftermarket options provide greater flexibility and customization. Raised and flush rail bars cater to different vehicle rail designs, and aero bars offer the best aerodynamic performance. Traditional square and round bars remain popular for their strength, and integrated bars provide a clean, all-in-one solution.
