About and Engineering
The design choices behind a more useful, serviceable aluminum truck-cap system.
BUILT AROUND ACCESS
Useful space, not just enclosed space.
GullWing caps are designed around everyday access, secure storage, serviceability, and modular use. Aluminum keeps the structure strong and corrosion-resistant while allowing the system to remain practical for work and travel.
Modular interior
Panels, storage, racks, and accessories can be configured around how the truck is actually used.
Serviceable hardware
Locks, struts, seals, hinges, and mounting components are designed with long-term ownership in mind.
ENGINEERING PRIORITIES
What matters in the design.
Final capacities and compatibility depend on the exact cap, truck, rack system, accessories, and operating conditions.
Structural load pathsSecure mounting and predictable support through the cap structure.
Door movementControlled opening, latch engagement, and practical service access.
Weather managementSealing, drainage, alignment, and compression designed as a system.
Vehicle-specific fitBed dimensions, cab clearance, tailgate operation, and accessory conflicts considered before install.
