Equip your vehicle with the KK Heavy-Duty Storage Case, strictly engineered for demanding off-road environments. Manufactured from a high-rigidity PP alloy, it reliably withstands severe temperature fluctuations (-40°C to 90°C) and heavy physical impacts without compromising its structural integrity. Featuring an IP67 water and dustproof rating supported by a professional-grade continuous rubber seal, it ensures your recovery gear, tools, and sensitive equipment remain completely dry and dust-free—even during deep river crossings or hours driving through fine desert dust. Capable of supporting a 100kg heavy-duty load, it provides uncompromising storage for serious touring.
WILL IT FIT MY RIG?
Universal Fitment: Our tents are designed to fit almost any vehicle year, provided you have an aftermarket roof rack, crossbars, or canopy with a dynamic load rating of 75kg or higher.
