Roof Rack Cross Bars: Your Essential Gear Hauler Guide
Roof rack cross bars are the backbone of any vehicle-mounted cargo system. They let you carry kayaks, bikes, luggage, and more safely on your car’s roof. Choosing the right set is crucial for security and ease of use. This guide helps you pick the best bars for your adventures.
Key Features to Look For
When shopping for cross bars, several features matter most. These features ensure your new bars fit well and carry your gear safely.
1. Fitment Type and Compatibility
- Fixed Mounting Points: Some cars have pre-installed bolts where racks attach directly. This offers the most secure fit.
- Raised Side Rails: These bars clamp onto the rails running front-to-back along the roof edge.
- Naked Roofs: These cars have no built-in rails or mounts. You need specialized towers and custom fit kits. Always check the manufacturer’s fit guide for your exact car model and year.
2. Bar Shape and Aerodynamics
- Aero/Wing Bars: These are oval or teardrop-shaped. They cut through the wind better, meaning less wind noise and slightly better gas mileage.
- Square Bars: These are simple, strong, and usually the most affordable. They often create more wind noise, especially at highway speeds.
- Load Capacity: Check the weight limit. Make sure it meets your needs for carrying heavy items like rooftop tents or multiple bikes.
3. Security Features
Look for bars that include locks. Locks stop thieves from easily removing your expensive cross bars or the gear attached to them.
Important Materials Used
The material determines strength, weight, and resistance to the weather.
Aluminum
Aluminum is very popular. It is lightweight and naturally resists rust. Aero bars are usually made from strong, extruded aluminum. This material offers a great balance of strength and low weight.
Steel
Steel bars are incredibly strong and often cheaper than aluminum. However, steel must be coated (usually powder-coated black) to prevent rust. Steel bars tend to be heavier.
Factors Affecting Quality
Not all cross bars are created equal. Quality comes down to design and construction.
Factors That Improve Quality
- T-Slot Channels: High-quality aero bars feature a channel running along the top. Accessories (like bike racks or cargo boxes) slide into this channel, making installation fast and secure.
- Durable Clamps/Towers: The parts that grip your roof must be made of tough, reinforced plastic or metal. Weak clamps fail first.
Factors That Reduce Quality
- Flimsy Plastic Parts: If the towers or end caps feel thin or cheap, they might crack under heavy load or extreme cold.
- Poor Finish: Scratches or chipping paint on steel bars show that the rust protection might be weak.
User Experience and Use Cases
How you plan to use your bars dictates the best choice.
Everyday Commuting
If you only carry a small cargo box occasionally, simple, quiet aero bars that fit your car well are perfect. Focus on low noise levels.
Weekend Warrior Adventures
If you constantly swap between carrying kayaks, skis, and mountain bikes, look for a system with quick-release towers. This lets you easily take the bars off when not in use, saving fuel and reducing wind noise.
Heavy Hauling
For rooftop tents or heavy building supplies, prioritize maximum load capacity and strong, square steel bars, even if they are a bit louder.
Roof Rack Cross Bar Buying FAQ
Q: Do I need cross bars if I only have side rails on my roof?
A: Yes. Side rails run front-to-back. Cross bars run side-to-side, connecting the rails. You need the cross bars to attach gear.
Q: Will cross bars hurt my car’s gas mileage?
A: Yes, any item attached to the roof increases wind resistance. Square bars cause more drag than streamlined aero bars. Removing them when not in use helps save gas.
Q: How do I know which cross bars fit my car?
A: Every major brand (like Thule or Yakima) provides an online fit guide. You enter your car’s year, make, and model, and it tells you the exact part numbers needed.
Q: Are the cheaper, universal bars a good idea?
A: Universal bars often require complicated measuring and might not fit perfectly or safely. For safety, always buy bars specifically designed for your vehicle type.
Q: What is the difference between a “fit kit” and a “tower”?
A: The tower is the main support piece that grips the roof. The fit kit is the custom foot pad and clamp specific to your car’s roof shape.
Q: Can I install cross bars myself?
A: Most modern systems are designed for DIY installation. They usually just require basic tools like an Allen wrench, which is often included. Read the instructions carefully.
Q: Are aluminum bars strong enough for heavy gear?
A: Yes, most quality aluminum bars have high load ratings, often 150 lbs or more. Always check the bar’s specific rating and your car’s roof limit.
Q: Should I get lockable cross bars?
A: Absolutely. Locks prevent easy theft of the bars themselves. If you leave them on the car all the time, locks are a must-have safety feature.
Q: Do cross bars come with attachments like bike racks?
A: No. Cross bars are the base system. Attachments like bike carriers, kayak cradles, or cargo boxes are sold separately and attach to the cross bars.
Q: How much noise should I expect from my new bars?
A: Square bars often create a noticeable whistling sound above 40 mph. Aero bars are much quieter, but some light wind noise is normal even with the best designs.
