Frequently Asked Questions
What size cargo shell do I need for my car?
The ideal size depends on your vehicle’s roof rack length, the type of gear you plan to carry, and your vehicle’s weight capacity. We recommend measuring your roof rack’s usable length and comparing it to the cargo shell’s dimensions. Consider your typical load: a 10-12 cubic foot shell is often sufficient for light luggage, while 16-20 cubic feet is better for camping gear or multiple suitcases. Always consult your vehicle’s owner’s manual for maximum roof load capacity.
Are cargo shells waterproof?
Most quality cargo shells are designed to be weather-resistant, offering excellent protection against rain, snow, and road spray. They typically feature tight-sealing lids and durable, UV-resistant materials. While they provide robust protection, labeling them as ‘fully waterproof’ can be misleading, as extreme conditions or prolonged exposure might allow minimal moisture in some designs. For sensitive electronics, we still recommend placing them in additional waterproof bags inside the shell.
How do cargo shells affect fuel economy?
A cargo shell will generally increase your vehicle’s aerodynamic drag, which can lead to a decrease in fuel efficiency. The extent of this impact depends on the shell’s size, shape, and how aerodynamically designed it is, as well as your driving speed. Low-profile, sleek designs are engineered to minimize this effect. We recommend removing the cargo shell when not in use to optimize fuel economy, based on aggregated owner feedback.
Can I install a cargo shell by myself?
Many modern cargo shells feature user-friendly mounting systems designed for single-person installation, especially smaller and lighter models. Systems with integrated torque indicators or quick-release clamps simplify the process significantly. However, larger or heavier shells may benefit from two people for lifting and positioning onto the roof rack to prevent scratching your vehicle or personal injury. Always follow the manufacturer’s specific installation instructions carefully.
Do cargo shells work with all roof racks?
Most cargo shells are designed to be compatible with a wide range of aftermarket and factory-installed roof rack crossbars, including square, round, and aerodynamic profiles. However, it’s crucial to verify the specific mounting system of the cargo shell you choose against the dimensions and type of your vehicle’s crossbars. Some cargo shells require a minimum and maximum crossbar spread, so checking these specifications is essential for proper fit and safe operation.
