Nitrogen Tank Suspension Refill Tool by RMT
Best for vehicle owners who rely on external nitrogen suspension tanks and need a reliable connection between the external gas source and the nitrogen suspension system. The tool set emphasizes professional-grade connections and a 10-foot hose for flexible reach. This option is especially suitable for Jeep Grand Cherokee, Ram 1500, and Tesla Model S users with nitrogen-based suspensions. A caution: the kit is designed for maintenance connections; always follow safety procedures when handling pressurized gas.
ZHSYMX 5 Gallon Air Tank
Best for users seeking a standard, compact air storage solution for onboard air systems and car horns. This 5-gallon aluminum tank is designed for durability with anti-corrosion coating and precision welding. It offers a straightforward option for adding an air reserve to a suspension or onboard air setup. Caution: ensure correct threading (NPT 1/4) for compatible fittings and avoid over-pressurizing beyond the rated limits.
CNRAQR 5 Gallon Air Tank
Best for a versatile air supply across multiple uses, including car air horns and onboard air systems. This 5-gallon aluminum tank is precision-welded with anti-corrosion coating for durability. It provides standardized capacity for reliable performance across various projects. Limitation: data indicates broad usage; verify compatibility with your specific suspension or horn setup before purchasing adapters.
Vixen Air Suspension Kit
Best for high-demand air ride and load-support needs. This kit includes a 5-gallon steel tank with multiple ports and dual 200 PSI compressors for rapid tank refill. It comes with a complete accessory pack, making it suitable for boat lifts, towing, lowering, and onboard horn systems. Caution: the setup is a robust system; installation may require mounting space and electrical considerations for compressors.
Air Lift Performance 12955 Aluminum Tank
Best for users seeking a compact, polished aluminum tank with multiple port options. The 4-gallon capacity and dual port arrangement support flexible configurations for suspension and other onboard air needs. Use this when space is a factor but you still require reliable air storage and straightforward integration.
EVIL ENERGY 1.5 Gallon Tank Kit
Best for compact, ready-to-install systems with six 1/4″ NPT ports and a 150 PSI rating. This kit includes a compressor, drain valve, hose, and mounting hardware, designed for quick setup in tight spaces. Consider this option when you need a small, integrated solution for suspension tweaks or horn systems. Caution: its smaller capacity means slower refill if you rely on rapid air delivery for heavy loads.
EVIL ENERGY 1 Gallon Tank Kit
Best for tight spaces and lightweight setups needing an onboard air source. This 1-gallon kit includes five 1/4″ NPT ports and a 150 PSI rating, plus a compact footprint. Choose this if you need a small, low-profile tank that can be mounted in cramped compartments, such as tight under-hood spaces or small trailers.
NBLYD 0.5 Gallon Tank
Best for spare capacity in a minimal footprint. The 0.5-gallon tank offers two 1/4″ NPT ports and 200 psi working pressure, making it suitable for compact horn systems or light-duty suspension tweaks in smaller vehicles. Limitation: the small capacity may not support sustained air supply during heavy-use scenarios.
Buying Guide: Key Considerations For Air Suspension Tanks
- Tank capacity and space: Larger tanks store more air and support longer operation between fills, but require more installation space. For small vehicles, consider 0.5–1 gallon tanks; for heavier loads or continuous use, 4–5 gallon tanks are preferable.
- Port configuration and fittings: Check port count and sizes (1/4″ NPT is common) to match hoses, compressors, and accessories. More ports offer flexibility but add complexity.
- Material and durability: Aluminum tanks are lightweight and corrosion-resistant; steel tanks are robust but heavier. Consider the environment and mounting location.
- Integrated kits vs. separate components: Full kits (tank, hoses, compressors) simplify installation and ensure compatibility. Separate components offer customization but require more setup.
- Pressure rating: Most automotive air systems operate around 150 psi; ensure tanks and components are rated for your target pressure to avoid over-pressurization risks.
- Intended use: If primarily for suspension leveling and quick fills, prioritize fast-fill capabilities and ample ports. If balancing a horn system or accessories, ensure the tank supports your additional needs.
- Installation considerations: Look for kits with mounting hardware and clear installation guidance. Respect vehicle space, wiring, and mounting strength to avoid vibration or fatigue.
Frequently Asked Questions
- What size air tank is best for suspension upgrades? – It depends on usage. For frequent load leveling and longer operation, 4–5 gallons is common; smaller tanks fit tight spaces or horns.
- Do I need a compressor with the tank? – Not always. Some setups use a separate compressor or a dedicated onboard air pump; for rapid refills, a twin- or high-flow compressor is advantageous.
- Is aluminum better than steel for tanks? – Aluminum is lighter and corrosion-resistant, while steel is durable and robust. Choose based on weight limits and environmental exposure.
- Can I mix tanks from different brands? – Mixing is possible if fittings and port sizes match, but compatibility and safety depend on proper pressure ratings and hoses. Always verify specs before combining components.
- What maintenance is required for air tanks? – Regularly inspect for leaks, drain moisture, and ensure port threads remain tight. Follow the kit’s maintenance guidance for long-term reliability.
- Are these kits legal for all vehicles? – Laws vary by region and application. Always verify local regulations and vehicle modifications before installation.
