The Ultimate Buying Guide for Roof Rack Cross Bars
Roof rack cross bars are essential tools for any adventure enthusiast. They let you carry extra gear on your car’s roof. Think kayaks, bikes, luggage boxes, or lumber. Choosing the right set means safe and easy transport. This guide helps you pick the best bars for your vehicle and needs.
Key Features to Look For
When shopping, look closely at these important features. They affect how well the bars work and how long they last.
- **Weight Capacity:** This is crucial. Check the maximum weight your bars can safely hold. Also, confirm your car’s roof can handle that weight. Don’t overload your bars.
- **Fitment System:** Bars must attach securely to your specific car. Some cars have existing side rails. Others need special towers that clamp onto the door frame. Always buy bars designed for your vehicle’s make, model, and year.
- **Aerodynamics:** Modern bars often have an oval or teardrop shape. This shape cuts through the wind better. This reduces wind noise and saves a little on gas.
- **Locking Mechanism:** Good bars come with locks and keys. This keeps thieves from stealing your expensive bars or the gear attached to them. Security is important.
- **T-Slot Channel:** Many premium bars feature a channel running along the top. This “T-slot” lets you easily slide accessories (like bike mounts) on and off without tools.
Important Materials That Matter
The material determines strength and resistance to weather.
Aluminum vs. Steel
- **Aluminum:** Most popular choice today. Aluminum bars are lightweight and naturally resist rust. They look sleek and often offer better aerodynamics. Quality aluminum bars are very strong.
- **Steel:** Steel bars are generally cheaper and extremely strong. However, they are heavier and usually coated with plastic or paint to prevent rust. If the coating scratches, rust can start.
Factors That Improve or Reduce Quality
Quality isn’t just about the price tag. It involves design and manufacturing.
Better quality is seen in the connections. Sturdy, thick mounting brackets significantly improve reliability. If the towers feel flimsy, the entire system might fail under heavy loads. High-quality weather stripping inside the clamps prevents scratching your car’s paint. Poor quality often shows up as thin metal or plastic parts that crack easily in cold weather.
User Experience and Use Cases
Think about what you plan to carry most often. This determines the bar style you need.
Common Uses:
- **Carrying Skis or Snowboards:** You will need specialized attachments that clamp onto the cross bars.
- **Transporting Kayaks or Canoes:** These require J-cradles or saddles mounted across the bars.
- **General Luggage or Cargo Boxes:** A flat, wide bar surface works best for these large items.
Installation difficulty varies. Some systems click on easily. Others require careful measuring and specific tools. Read reviews to see how long installation takes for the average person. Easy installation means you spend more time adventuring and less time wrestling with bolts.
10 Frequently Asked Questions (FAQ) About Roof Rack Cross Bars
Q: Do I need cross bars if my car already has side rails?
A: Yes. Side rails run front to back along the roof edges. Cross bars run side to side, connecting the two side rails. You need cross bars to attach gear.
Q: Will cross bars hurt my gas mileage?
A: They will cause a slight decrease in gas mileage. This happens because they create more wind resistance (drag). Aerodynamic bars cause less drag than square, older-style bars.
Q: Can I install cross bars myself?
A: Many kits are designed for DIY installation. If your car has factory mounting points, installation is usually simple. If you are unsure, a professional installer at an auto shop can mount them for you.
Q: What is the difference between fixed mounting and flush mounting?
A: Fixed mounting uses pre-drilled holes on your roof. Flush mounting means the bars sit directly against the roofline with no visible towers sticking up.
Q: Are cross bars safe in heavy rain or snow?
A: Yes, if they are properly installed and rated for your vehicle’s load. The bars themselves will not leak water into the car. Always check that your attached gear is waterproof.
Q: How tight should I make the clamps?
A: You should tighten them until they feel very secure, often using a torque wrench to meet the manufacturer’s exact specification. Overtightening can damage your roof rails.
Q: Are cheap, universal cross bars a good idea?
A: Usually, no. Universal bars often fit poorly, leading to noise, slippage, or damage to your paint. Always choose bars specifically made for your car model.
Q: Do I need to remove them when I am not using them?
A: If you drive mostly around town, removing them reduces wind noise and saves fuel. If you use them often for bikes or kayaks, keeping them on is fine.
Q: How do I clean rust off my steel cross bars?
A: Gently sand the rusted area. Apply a rust converter product, and then repaint the area with a durable exterior paint to seal the metal again.
Q: Can I fit two different accessories on my two cross bars?
A: Yes, if you have enough space between the two bars. You must ensure the combined weight of both accessories and cargo stays under the weight limit.
