If you're gearing up for an Overlanding escapade, a camping retreat, or a family getaway, odds are you're eyeing some roof bars. Unless you have specific requirements in mind, universal roof bars are the optimal choice. However, there are several factors to mull over before making a purchase. It's crucial to recognize that while the racks themselves are universal, the fittings linking them to the vehicle are tailored to specific vehicle types or models.
The use of roof bars can provide you with many benefits. Simply grabbing the first set of roof bars you encounter and affixing them to your vehicle isn't advisable. Numerous considerations come into play when procuring and installing universal roof bars on your car or truck. For instance, you'll need to contemplate the rack system that best suits your vehicle's roof design.
Equally vital is determining the weight capacity your vehicle's roof can handle, and verifying the legality of roof bars in your area. Below, you'll find an exhaustive rundown of the key factors to ponder before embarking on the installation of universal roof bars.
Get to Know Universal Roof bars
Are Roof Bars Illegal?
One of the primary and most critical questions to consider before investing in roof bars is their legality. If you're planning a journey across different states or even the country, it's crucial to familiarize yourself with the specific regulations governing roof bars and cargo loading in each state. Failure to adhere to these regulations could lead to substantial fines.
While roof bars themselves are generally permitted nationwide, individual states have their own traffic laws governing their use. For instance, in West Virginia, roof bar lights are allowed as long as they're not activated while driving on state roads or highways. On the other hand, California permits light bars but requires them to be covered when not in use. Although only 16 states have specific laws regarding improper loads, it's still vital to understand and comply with any applicable limitations and regulations.
Regardless of the state, it's illegal across the entire United States for items to drop or fall from a vehicle. Violating this law could result in fines or even imprisonment. Therefore, it's essential to securely fasten any items to your roof each time you travel to avoid potential legal consequences.
What Roof Bars Will Fit My Car?
Understanding the type of roof system your vehicle has is essential prior to buying roof bars. Why? Because various vehicle brands and models feature distinct roof designs, necessitating specific installation methods and fittings for attaching roof bars. Your vehicle's owner's manual provides this information, detailing the roof system and compatible roof bar systems. Alternatively, you can visually inspect your vehicle's roof to determine the required roof bar system. Here's a breakdown of compatible roofing systems and corresponding roof bar styles:
Bare or Naked Roof Systems
These car roofs lack provisions for attaching roof bars, such as rails, rain gutters, or fixed mounting points. In such cases, clamp-on crossbars or a roof bar system can be bolted onto the vehicle by drilling holes into the roof's body. An example of this setup is the installation of an overland rack on a Ford Ranger.
Fixed Point Systems
These roof systems feature four pre-installed fixed-points where you can securely attach your roof bars. These points are typically covered by caps or weather-trim. The roof bar systems include crossbars that connect to these fixed points. The Toyota Tacoma Cab Rack utilizes this setup.
Rain Gutter Systems
In this roof design, a rain gutter runs along the roof's edge, commonly seen in vehicles like Jeeps, exemplified by the Jeep Overland roof bar. These systems require roof bars with specialized feet and clamps that fit into the rain gutters and securely fasten to them. However, this style of roof system is considered outdated and is rarely seen in modern cars.
Raised Rails
These vehicles are equipped with factory-installed roof rails that function similarly to roof bars. Crossbars featuring specialized feet clamp onto these raised rails. Another example of this setup is seen in the Jeep Grand Cherokee with its dedicated roof bar system.
The Capacity of My Car
Determining your car's capacity is crucial. Your vehicle's user or owner’s manual outlines its load-bearing capabilities. If you don't have the manual, contact a dealership or search online for this information. Overloading your vehicle not only risks hefty fines but also increases the likelihood of accidents.
Understanding dynamic capacity, the load your car can bear on the roof while in motion, is vital. Most cars, trucks, and SUVs can typically support up to 165 pounds. For instance, a Toyota Rav 4 has a capacity of only 100 pounds. It's crucial to know your car's dynamic capacity, as exceeding it poses risks, even if your roof box can accommodate more weight.
However, don't confuse dynamic capacity with static capacity, the load a vehicle can support while stationary. Static capacity is often higher than dynamic capacity. When loading your car, adhere to the dynamic capacity, as a heavier load increases the force on your vehicle when moving. This strains your brakes, potentially leading to brake failure or longer braking distances.
Overloaded vehicles may struggle to stop promptly, increasing the risk of accidents, especially in emergency situations. Additionally, overloading affects handling, as vehicles are designed with weight evenly distributed and close to the ground for stability during turns. Placing a load on the roof shifts the center of gravity, compromising cornering ability and increasing the risk of rollovers.
How do I Know the Size?
Roof bars are available in various sizes, and selecting the right one depends on your vehicle. It's crucial to acquire the correct size roof bars for several reasons. Many states enforce traffic laws concerning allowable overhang. Your roof bars should not protrude beyond a specified distance from your car roof, as doing so can result in fines. Additionally, excessively long roof bars may prevent your vehicle from fitting into your garage. Extended roof bars can also disrupt your car's aerodynamics, leading to increased drag and fuel consumption. Furthermore, the handling of your vehicle may be compromised.
What accessories to choose to work with my roof bars?
Determining the accessories you plan to use with your roof bars will influence the size and design you choose. The width of the crossbar dictates how many accessories you can accommodate on your roof bar system. Among the overland accessories available are cargo boxes, bicycle racks, kayak holders, and rooftop tents.
Will my roof bars need any maintenance?
Maintaining roof bars is crucial. One vital aspect is ensuring they are securely fixed. We recommend checking their stability every 1000 km traveled by giving them a firm shake in all directions to detect any need for tightening. If your car isn't parked in a garage, consider removing the roof bars when not in use to prolong their lifespan. Additionally, if your roof bars are removable, remember to take them off before getting your vehicle cleaned at a car wash.
Conclusion
Understanding roof bars is crucial for various reasons. Familiarizing yourself with your vehicle, its compatible roof bars, and dynamic capacity enhances safety during your journeys while avoiding fines. Knowing your car's roof system prevents wasted time and money on incompatible roof bars. Regular maintenance ensures optimal performance and longevity of your roof bar system.
