When it comes to off-road adventures, having the right equipment is essential, and that includes how you transport your gear. For many off-road enthusiasts, vehicle rooftop storage is a game-changer. But with so many options available, how do you choose the right setup for your lifestyle? The two most popular choices are roof racks and crossbars, and each comes with its own advantages and drawbacks.
This detailed guide will break down the differences between roof racks and crossbars, helping you decide which is the optimal choice for your vehicle and your next off-road escapade.
At first glance, roof racks and crossbars may seem similar—they both are rooftop solutions for carrying cargo. However, their designs, installation methods, and applications make them distinct. Here's a quick overview:
![]() Roof Racks are large, multi-bar platforms that span across the roof of your vehicle. They can usually hold heavier and bulkier items such as RTTs (roof-top tents) or storage solutions. |
Crossbars, on the other hand, consist of horizontal bars (usually sold as in pairs, bundles, or individually) that attach to your vehicle's side rails, supporting cargo directly or connecting to cargo accessories. |
Now, let's explore these differences in detail
Roof racks typically mount directly to your vehicle’s factory mounting points or include side rails as part of their frame. This design makes roof racks compatible with vehicles that don’t have pre-installed side rails. With their more robust mounting platform, roof racks can often support greater weight and provide more stability for larger cargo like tents or equipment for extended expeditions.
Crossbars are designed to sit atop side rails (either factory-installed or aftermarket). Vehicles with side rails make crossbars an easy and straightforward choice. However, if your car doesn’t have side rails, you’ll need a durable mounting system to accommodate them.
If flexibility in positioning sounds appealing to you, crossbars are highly adjustable, allowing you to mount them closer or farther apart as needed.
Roof racks generally offer limited flexibility in configuration. Many are pre-designed with fixed bars or provided with slight adjustability for bar positioning. While they often include multiple support beams for enhanced cargo stability, the trade-off is typically lower modularity compared to crossbars. Still, higher-end racks sometimes allow you to add or remove bars based on your specific needs.
Crossbars shine when it comes to modular setups. Since you can typically purchase one crossbar at a time or in pairs or bundles, you have more freedom to assemble a configuration that matches your exact requirements. This system is especially useful for those who need versatility, as crossbars can be reconfigured depending on what kind of cargo you plan to carry.
Roof racks can be more complex to install and in some cases can require professional assistance due to their size and weight. Mounting them involves securing multiple points of contact with precision, ensuring proper weight distribution. While this may require more time and effort upfront, the result is a highly sturdy and reliable system.
Crossbars are generally easier to install, especially if your vehicle already has factory-installed side rails. Most crossbars are beginner-friendly, coming with straightforward installation instructions and requiring minimal tools. If you don’t have much experience installing things like this, crossbars are a more accessible option.
Price can play a major role in the decision-making process. Here's how roof racks and crossbars stack up:
Crossbars are typically more budget-friendly. You can purchase a single crossbar or an entire package, making it easier to spread out costs. This incremental buying option is ideal for those looking to experiment with rooftop storage without committing to a large investment upfront.
Roof Racks, due to their size, engineering, and higher weight capacity, are generally more expensive. They’re designed to last for years and accommodate demanding needs, making them a worthy investment for serious adventurers.
When it comes to carrying capacity, both systems have their strengths. But first, let’s talk about load ratings.
When it comes to determining how much weight you can carry up top, roof racks and crossbars are not created equal! Roof racks mount directly to the vehicle and would be subject to your vehicle’s load ratings for your roof. Whereas crossbars are subject to your vehicle’s load ratings for the factory side rails, which tends to be quite a bit lower. Let’s take a look at the 2010-24 Toyota 4Runner as an example:
Factory Side Rails (used for Crossbars) = 135 lbs while moving
Roof (used for Roof Racks) = 300 lbs while moving
So it’s important to keep in mind how much weight you plan to carry to ensure you are not exceeding your vehicle manufacturer’s recommended load ratings. This is also why we don’t put load ratings on our LFD Crossbars and Roof Racks – even though our roof racks could probably handle 2,000 lbs of cargo, the vehicle can’t!
Roof Racks:
Roof racks excel at carrying more cargo and supporting heavier loads. They’re ideal for bulky equipment like roof-top tents (RTTs), large luggage, off-road jacks and other heavy tools and equipment, or sports gear. Their full-frame design ensures even weight distribution, protecting your car’s integrity even under pressure. But even though most racks are built to be incredibly strong, you never want to exceed your vehicle’s rooftop load ratings!
While crossbars typically can’t handle as much weight as roof racks, they’re perfectly suited for lighter loads like kayaks, bikes, skis and snowboards, smaller cargo boxes or a few pieces of lumber. We’ve also seen them work well for smaller and lighter weight roof-top tents. This makes them a great option for occasional adventurers or those who don’t carry large quantities of gear. Just make sure you’re not exceeding your vehicle’s side rail load ratings!
Both roof racks and crossbars will affect your vehicle’s aerodynamics, fuel efficiency, and stability to some degree.
DID YOU KNOW? LFD Off Road roof racks incorporate specially designed wind fairings to improve aerodynamics. We also offer wind fairing front crossbars!
Due to their larger size and higher profile, roof racks can influence your vehicle’s center of gravity and increase wind resistance. This may reduce fuel efficiency slightly and affect handling if carrying particularly heavy loads.
Crossbars have a smaller footprint, resulting in fewer changes to vehicle dynamics. They tend to be more fuel-efficient and less likely to disrupt handling. If you need a solution that minimizes aerodynamic drag, crossbars are often the better option.
A roof rack might be the right choice for you if:
You need to carry large or heavy gear, like roof-top tents or lots of equipment.
Your off-road adventures require a highly durable and dependable rooftop system.
You want a long-term solution with maximum cargo capacity.
Roof racks are engineered for serious adventurers who need secure, rugged storage that can handle both on-road and off-road challenges.
Crossbars might be a better fit if:
Your vehicle already has side rails, and you’re looking for an easy-to-install solution.
You prioritize cost-effectiveness and modularity.
Your cargo needs vary from trip to trip and consist of lighter or smaller items.
Crossbars are a versatile and practical option, especially for weekend explorers or those new to rooftop storage.
Here’s a summary of what to think about when deciding between roof racks and crossbars:
Your Vehicle’s Side Rails:
Does your car have factory-installed side rails? If not, a roof rack may be more practical.
Budget:
Determine how much you’re willing to spend. Crossbars are more economical, while roof racks provide long-term value for demanding needs.
Cargo Specifics:
Consider what you’ll be carrying. Roof racks are best for heavy or bulky items, while crossbars excel with lighter loads.
Ease of Installation:
Crossbars are quicker to install, but roof racks offer greater strength and security.
Whether you’re gearing up for a weekend camping trip or a cross-country expedition, the right rooftop storage can make all the difference. Carefully evaluating your needs, vehicle setup, and budget will help you choose between roof racks and crossbars.
Both options offer unique advantages, but the choice comes down to what fits your lifestyle best. Equipped with this knowledge, you’re ready to make the call and hit the trails.
