Air Tanks for Air Suspension & Onboard Air Systems

Shop onboard air tanks and compressed-air reservoirs for air suspension, vehicle accessories, mobile air systems, and custom performance builds. Black Ops Auto Works offers Kleinn, Firestone, and Granatelli air tanks in compact, mid-size, and high-capacity configurations for street trucks, show vehicles, off-road rigs, trailers, work vehicles, and custom air-management systems.

An air tank stores compressed air so compressors do not need to run continuously when operating air suspension, air horns, pneumatic accessories, tire-inflation equipment, or other onboard-air components. The correct tank depends on available space, required air volume, compressor output, operating pressure, port size, mounting location, and intended use.

Air Tanks for Air Suspension and Onboard Air Systems

Use a properly sized air reservoir to support faster system response, reduce compressor cycling, and provide stored air for repeated adjustments. These tanks can be paired with compatible compressors, manifolds, pressure switches, gauges, air lines, fittings, and electronic management systems.

Available air-tank sizes include:

• Compact 0.25-gallon and 1-gallon tanks
• 1.5-gallon and 2.5-gallon tanks for space-limited installations
• 2.6-gallon and 3-gallon tanks for custom vehicle systems
• 3.3-gallon and 5-gallon tanks for larger air demands
• 20-gallon tanks for high-capacity onboard-air applications

Kleinn, Firestone, and Granatelli Air Tanks

This collection includes compact Kleinn tanks, universal Granatelli aluminum tanks, and Firestone steel air tanks with multiple port configurations. Granatelli portable aluminum tanks are useful for mobile air applications and may include a hose and pressure gauge, while Firestone tanks provide larger-capacity storage for onboard air systems that require increased volume.

Firestone tank options in this collection include 150 PSI maximum-pressure configurations with 1/4-inch, 3/8-inch, or 1/2-inch NPT ports, depending on the product. Always verify the tank’s material, dimensions, port size, maximum pressure, and included accessories before ordering.

Choosing the Correct Air Tank Size

Tank capacity should match the air demand of the complete system. A smaller tank may be appropriate for a compact air-suspension or pneumatic-accessory installation, while a larger reservoir is better suited for repeated height adjustments, multiple air accessories, heavy-duty use, or systems with higher air consumption.

Consider the following before selecting a tank:

• Available mounting space and tank dimensions
• Required air volume and frequency of use
• Compressor output and duty cycle
• Maximum operating pressure
• NPT port size and port quantity
• Air-line size, fittings, valves, and manifold compatibility
• Vehicle weight, intended use, and mounting location
• Included hose, gauge, brackets, or mounting hardware

Air Tank Installation and Safety

Install the tank securely to a structurally sound mounting surface and protect it from road debris, excessive heat, corrosion, and physical damage. Route air lines away from exhaust components, sharp edges, suspension travel, and moving parts. Use fittings and hoses rated for the system’s operating pressure, and check all connections for leaks before placing the system under load.

Drain the tank as required to remove moisture and condensation. Never exceed the manufacturer’s maximum pressure rating, and inspect the tank regularly for corrosion, dents, damaged ports, or other signs of unsafe condition. Professional installation is recommended for custom pneumatic and air-suspension systems.

Air Tanks for Custom Vehicle Builds

Air tanks are commonly used with air suspension, air horns, onboard air compressors, pneumatic tools, tire-inflation systems, and other vehicle-mounted accessories. For complete management components, pair the correct tank with compatible air controls and suspension equipment, such as the AccuAir air suspension collection.
