Buyer's Guide: Roof Boxes for 4x4's, cars & pick-ups | Predator 4x4 UK
Looking for the perfect roof box for your 4×4 or car? This expert buyer’s guide from Predator 4×4 helps you choose the ideal roof storage solution for any UK road trip or adventure.
Why Choose a Roof Box for Your Car or 4x4?
Whether you’re heading out on a camping trip, loading up for a holiday, or simply need more boot space, a roof box is the ultimate solution for extra storage. At Predator 4×4, our rugged, adventure-ready roof boxes are built to tackle both urban and off-road journeys with ease.
In this guide, we’ll walk you through everything you need to consider when deciding which of our roof boxes is best suitable for you.
1. Choose the Right Roof Box Size for Your Needs
Roof boxes are available in various sizes, and it’s crucial to match the volume and dimensions to your needs and vehicle type.
Small Roof Boxes (250–350L)
Ideal for small cars or occasional use
Perfect for short getaways or carrying camping essentials
Medium Roof Boxes (350–450L)
Great for family cars and SUVs
Ideal for weekends away, sports gear, or moderate luggage
Large Roof Boxes (450–600L)
Best for 4x4s, off-road vehicles, and long-distance travel
Easily fits bulky gear like tents, skis, and pushchairs
Pro Tip: Always check your vehicle’s maximum roof load limit and measure the roof box length to ensure it won’t interfere with tailgate access.
2. Mounting System: Quick Fit or Traditional?
Our Predator roof boxes are compatible with universal roof bars, and different mounting systems offer different benefits:
U-Bolt Mounting
Tried and tested. Reliable and cost-effective.Quick-Fit/Clamp Systems
Tool-free, fast installation—ideal if you plan to remove the box frequently.
Before buying, confirm your roof bar spacing and type (square vs. aero bars) for optimal fit.
3. Construction: Strength, Weight & Weather Resistance
Predator roof boxes are crafted from impact-resistant ABS plastic—a lightweight yet durable material designed to withstand UK weather and tough terrain.
What to Look For:
UV-resistant materials to avoid sun damage
Waterproof seals to keep contents dry
Strong hinges and locks for long-term reliability
4. Security and Accessibility Features
Keeping your cargo safe is a priority, especially when parked up on an adventure.
Key Features to Consider:
Central Locking System: Locks all access points with one key for convenience and safety.
Wide Lid Opening: Access your gear from any angle —a big plus in tight parking spaces.
Anti-theft locks: Prevent unwanted tampering on and off the road.
5. Aerodynamics = Better Fuel Efficiency
Due to the changes in aerodynamics that roof boxes cause, you will see a slight decrease in fuel efficiency. As well as the extra weight of both the box and it’s content, you’ll also be creating extra drag – known as air resistance.
To battle this, our roof boxes are designed to be as aerodynamic as possible, with sleek, smooth shells and tapered edges, they aim to be as fuel efficient as possible.
Note: For best results, remove the roof box when it’s not in use to restore maximum efficiency.
6. Storing Your Roof Box When Not in Use
Roof boxes take up space when not mounted, so plan ahead:
Wall or ceiling hoists (garage-friendly)
Protective covers for long-term indoor storage
Store upside down to avoid warping over time
7. Additional Tips Before You Buy
Insurance Notice: Adding a roof box can count as a modification—always inform your insurer.
Height Clearance: With a roof box fitted, check your new total height for car parks and ferry access.
Load Balance: Pack heavier items in the centre, lighter ones at each end, and secure them inside with straps.
