Yes, this side window expansion tank system is designed for GWM Tank 300 models from 2021 to 2026. Your 2023 Tank 300 is fully compatible with the system, which utilizes the clever side window space to add extra storage capacity for your off-road adventures.
Both come in the same 7.5L capacity and color options (Black, Red, Orange), but the Tap Model Tank includes a tap/valve mechanism for easier fuel or liquid dispensing. Choose the standard Tank if you prefer a sealed container, or select the Tap Model (SKU4, SKU5, or SKU6) if you need convenient access to the contents during your expeditions.
The expansion tank is constructed from high-strength polycarbonate (PC material), which is rigorously tested to withstand complex road conditions and ensure long-lasting durability. The system also features aggressive mecha-style mesh guards with a hard-lined design that provides both secure attachment points and the combat-inspired aesthetics that elevate your Tank 300's off-road presence.
Installation involves six main steps: removing the original rail cover, inserting slider screws into the roof luggage bar rails, positioning the mesh panel, and securing both front and rear brackets with provided hardware. The process requires basic tools (typically a wrench or socket set) and should take 30–45 minutes. The installation guide emphasizes checking door clearance and verifying bracket alignment to ensure stability and proper weight distribution.
The package includes one each of Black, Red, and Orange 7.5L tanks, plus one each of the Tap Model variants in the same colors (6 tanks total), the side window mecha guards, and an anti-theft oil drum holder. This gives you multiple color and functional options to personalize your Tank 300 while keeping your off-road gear secure and organized.
Yes — we offer the side window mecha package (SKU7) and the anti-theft oil drum holder (SKU8) as individual SKUs, so you can customize your setup. If you want to add these components to an existing system or upgrade your Tank 300 without purchasing the full tank bundle, you can order them separately.
The installation process includes a critical step to check door clearance — you must position the front bracket far enough back to allow your car door to open fully without jamming. Following the installation guide carefully and verifying alignment of the left and right brackets ensures the system integrates safely with your Tank 300's existing features and maintains full functionality.
