Your Guide to Choosing the Best Hard Shell Car Top Carrier
A hard shell car top carrier is a fantastic way to get extra storage space for your car trips. It sits right on your roof and keeps your gear safe and dry. Picking the right one means checking a few important things. This guide will help you find the perfect box for your adventures.
1. Key Features to Look For
When you shop, focus on these main features. They make a big difference in how well the carrier works.
Capacity and Size
- Volume (Cubic Feet): Think about how much stuff you need to carry. Small families might need 10-13 cubic feet. Big trips or ski gear might need 18 cubic feet or more.
- Dimensions: Make sure the carrier fits on your roof without blocking your trunk or tail lights. Check the length, width, and height.
Security and Access
- Locking System: A good carrier must have strong locks. Look for dual-sided opening so you can reach your gear from either side of the car.
- Mounting Hardware: How easily does it attach to your roof racks? Quick-install systems save a lot of time and frustration.
Aerodynamics
A sleek, low-profile shape cuts down on wind noise and helps save gas. Boxes with smooth, curved edges are usually quieter on the highway.
2. Important Materials and Durability
The material determines how long your carrier lasts and how well it protects your things.
Shell Material
- ABS Plastic: This is the most common material. It is light, strong, and resists dings well. High-quality ABS plastic handles UV rays (sunlight) better, so it won’t get brittle quickly.
- Polycarbonate: This material is even tougher and more impact-resistant than standard ABS. It costs a bit more but offers superior protection against road debris.
Hardware
Check the hinges and mounting hardware. Stainless steel or heavy-duty aluminum parts resist rust better than cheaper metal parts. Strong hinges ensure the lid stays open when you load it and stays shut when you drive.
3. Factors That Improve or Reduce Quality
Not all hard shell carriers are made equal. These details separate the great ones from the average ones.
Quality Boosters
- Weatherproofing Seals: Thick rubber gaskets around the lid create a tight seal. This keeps rain, snow, and dust out completely.
- Weight Capacity: A higher weight limit means the box structure itself is stronger and can handle heavier items like camping stoves or tools.
- Internal Straps: Built-in straps help secure loose items inside so they do not bounce around during bumpy drives.
Quality Reducers (Things to Avoid)
- Flimsy Latches: If the locks feel weak or thin, they can easily break or be pried open.
- Poor Fit on Roof Racks: Carriers that only fit one specific type of roof rack limit your options later. Universal mounts are usually better.
- Excessive Noise: If the plastic flexes a lot in the wind, you will hear annoying whistling or booming sounds on long drives.
4. User Experience and Use Cases
Think about *how* you plan to use the carrier. This shapes your best choice.
Road Trips and Family Travel
For long family vacations, capacity and easy access are key. You need space for luggage and pillows. Look for dual-sided opening so parents can grab a snack or blanket without walking around the car.
Sports and Outdoor Gear
If you carry skis, snowboards, or fishing rods, look for carriers designed specifically for length. Some models have internal foam padding to protect sensitive equipment.
Installation and Removal
If you only use the carrier a few times a year, fast, tool-free installation is a lifesaver. If you leave it on all the time, aerodynamics and gas mileage become more important.
Top 10 Frequently Asked Questions (FAQ) About Hard Shell Carriers
Q: Do hard shell carriers hurt my gas mileage?
A: Yes, they slightly hurt your gas mileage. A large box creates more wind resistance (drag). Driving slower and choosing an aerodynamic model helps reduce this effect.
Q: Can I still use an automatic car wash with the carrier on?
A: Generally, no. Most car wash facilities require you to remove roof carriers first. The brushes can damage the box or the mounting hardware.
Q: How much weight can a hard shell carrier usually hold?
A: Most standard carriers hold between 100 to 165 pounds. Always check the carrier’s limit AND your car’s roof weight limit, as the car limit is often lower.
Q: Are hard shell carriers waterproof?
A: High-quality hard shell carriers are designed to be highly water-resistant, often waterproof, thanks to good sealing around the edges. Lower-quality ones might leak in a heavy storm.
Q: What is the difference between ABS and Polycarbonate?
A: ABS is very good, common plastic. Polycarbonate is stronger, more flexible, and resists cracking better, especially in very cold weather.
Q: Do I need roof racks already installed?
A: Yes. Hard shell carriers mount onto existing crossbars (roof racks). If you do not have crossbars, you must buy those first.
Q: How long does it take to install one?
A: With modern quick-mount systems, installation can take as little as 15 to 30 minutes. Older or simpler systems might take closer to an hour.
Q: Are they noisy on the highway?
A: Aerodynamically shaped models are quiet. Boxy or older models often create wind noise, especially above 50 mph.
Q: Can I open the carrier lid if I park under a low ceiling?
A: Check the height clearance. A fully loaded carrier can add 15 to 20 inches to your vehicle’s total height. Measure your garage opening before buying.
Q: What should I do before I put my gear in?
A: Always place the heaviest items near the center of the carrier, directly over the car’s crossbars. This keeps the weight balanced and protects your roof.
