What Material are in our upfits?

We use premium heavy-duty materials across our entire upfitting series, including high-strength aluminum, reinforced steel, impact-resistant acrylic, and other industrial-grade composites. All parts are rust-proof and corrosion-resistant—specifically engineered to stand up to road salt, a common challenge for North American vehicles. They are also UV-resistant to prevent fading and degradation from long-term outdoor exposure, ensuring years of reliable heavy-duty use even in harsh conditions.

Is Installation Easy?

Absolutely. Our Truck and van upfits parts feature a bolt-on design that requires no special tools for installation. Detailed, easy-to-follow instructions are included with every product, allowing you to complete the setup quickly and efficiently. Most parts can be installed by a single person, and our design ensures no damage to your vehicle’s original structure—keeping your truck in perfect condition while adding functionality.

How Safe Are They?

1. Superior Overall Stability: Every component—from Pickup Cargo Racks and truckunder liftgates,From small parts to finished products—is engineered for exceptional stability. They are rigorously tested to ensure no shaking, loosening, or tipping, even at high speeds, when bearing heavy loads, or during frequent use, eliminating safety hazards during work or transport.

2. Anti-Slip Protection for Climbing & Loading: All climbing and loading-related parts are equipped with anti-slip safeguards. Our ladder and ramp series feature anti-slip textures or rubber mats on steps to prevent slipping,ensuring secure footing for users and stable movement for cargo, even in rainy or oily conditions.

3. Durable Anti-Break & Anti-Loose Construction: All components are built with heavy-duty, high-strength materials to resist breakage, deformation, and loosening. This includes structural parts designed with reinforced joints, sturdy fasteners, and robust frames to ensure long-term safety and reliability in heavy-duty work scenarios.

4. Lockable or anti-theft options: Many products integrated high-security locks, tamper-resistant hinges, and reinforced locking mechanisms, which keep your valuable tools, sensitive cargo, and custom upgrades secure whether your vehicle is parked at job sites, loading docks, or public parking areas.
