A strong truck air tank provides the storage capacity, pressure rating, and port layout your air-brake, suspension, horn, or onboard-air system requires. These options range from compact 1.6-gallon reservoirs to an 8-gallon steel tank, with both general-purpose tanks and a dedicated replacement air-brake reservoir. For broad truck use, Vixen Air 6 Gallon Tank stands out with a stated 200 PSI capacity, nine ports, and several port sizes; buyers replacing a specific Peterbilt air-brake tank should instead start with the Mytee Products Twin Chamber Tank and confirm part-number fitment.
The list also includes kits with useful fittings and controls, along with tanks that supply only the reservoir. Compare pressure, port threads, capacity, construction, and installation needs before choosing.
Vixen Air 6 Gallon Tank is the strongest general-purpose pick in this group because its steel construction, stated 200 PSI rating, and nine ports suit a range of air-suspension and train-horn setups. Its 19.75-by-9.38-by-11-inch dimensions and mix of 1/2-, 3/8-, and 1/4-inch NPT ports help buyers plan an installation. For a specific Peterbilt air-brake replacement, choose Mytee Products Twin Chamber Tank instead and verify the listed OEM numbers against the truck.

Detailed Reviews: Best Air Tanks For Trucks

#1 · Best Overall
1. Vixen Air 6 Gallon Tank
- Material Type: Alloy Steel
- Weight: 17.2 lb
- Compatible with Vehicle Type: Vehicle
Best for: Six-gallon nine-port systems.
Why it ranks #1: Its 6-gallon steel tank supports up to 200 PSI and has nine ports in three NPT sizes for varied truck air-suspension or horn plumbing.

#4 · Best Brake Replacement
4. Mytee Products Twin Chamber Tank
- Material Type: Alloy Steel
- Weight: 25.8 lb
- Compatible with Vehicle Type: Truck
Best for: Peterbilt brake-tank replacements.
Why it ranks #4: Its twin-chamber, 2,267-cubic-inch design is a truck air-brake reservoir and lists Peterbilt replacement numbers, including 08-02347 and 802347.
A twin-chamber layout with 2,267 cubic inches of volume makes this Mytee Products tank a specific replacement choice for listed Peterbilt and Automann air-brake applications. Seven NPT-threaded ports support air-system connections, while the reservoir’s stated function is maintaining consistent pressure for braking and suspension functions.
The listing identifies replacement references including Peterbilt 08-01276, 08-02347, and 802347, as well as Automann 172.2347, helping buyers match the tank to a specified replacement application. Its seven NPT ports comprise three main ports and four end ports; the main-port inside diameter is 0.5 inch. The twin chambers and 2,267-cubic-inch capacity serve braking and suspension pressure storage, while the alloy-steel body measures 32 inches long and 9.5 inches in maximum diameter.
- Twin-chamber air-brake reservoir
- 2,267 cubic inches of capacity
- Seven NPT ports, including three main ports
- Listed for specific Peterbilt and Automann replacements
- Its listed fit is specific to certain Peterbilt and Automann replacement applications.
Skip it if you need a general-purpose horn or onboard-air tank rather than a specified Peterbilt or Automann brake-tank replacement.

5. HornBlasters 5-Gallon Tank
- Material Type: Alloy Steel
- Weight: 8.3 kg
Best for: Five-gallon seven-port builders.
Why it ranks #5: The powder-coated steel 5-gallon reservoir has seven 1/2-inch ports and is specified for air horns, air suspension, and onboard-air systems.
Seven 1/2-inch ports distinguish HornBlasters’ five-gallon steel tank, giving air-system builders a consistent larger port size across its connection points. The powder-coated alloy-steel reservoir is listed for compatible air horns, air suspension, and onboard-air systems, so it can serve truck owners planning one of those pneumatic setups.
Five gallons of storage gives a compatible air-management system a stated reserve, while the seven 1/2-inch ports provide connection points for the equipment in a build. Alloy steel and a powder-coated finish are specified alongside corrosion-resistant construction, which supports use in demanding environments. Mounting hardware is included, and the tank measures 26.5 by 8 by 9.5 inches; compare those dimensions and port size with the available mounting area and plumbing before installation.
- Five-gallon air storage
- Seven 1/2-inch ports
- Powder-coated alloy-steel construction
- Mounting hardware included
- All seven ports are 1/2 inch, limiting direct use with plumbing that requires smaller ports.
Skip it if you need mixed port sizes without adapters; every listed connection on this tank is 1/2 inch.
Truck owners adding a five-gallon reserve for compatible horns, suspension, or onboard air can consider this seven-port tank. Its uniform 1/2-inch ports and 26.5-inch length are the key plumbing and space boundaries.

6. VIAIR 91050 Tank
- Material Type: Alloy Steel
- Weight: 11.5 lb
Best for: Mixed-port five-gallon setups.
Why it ranks #6: This 5-gallon steel reservoir has a corrosion-resistant powder coat, two 3/8-inch and two 1/4-inch NPT ports, and a 150 PSI maximum.
Two 3/8-inch NPT ports and two 1/4-inch NPT ports give VIAIR’s five-gallon reservoir a useful mixed-port layout for truck air systems. Its 150 PSI maximum working pressure sets a clear operating ceiling, while the steel tank’s 20.5-by-9-by-10.5-inch dimensions help buyers assess installation space.
The mixed port sizes let a builder connect equipment using either 3/8-inch or 1/4-inch NPT fittings without treating all four connections as one size. Five gallons supplies the listed storage capacity, and the 150 PSI maximum working pressure defines the tank’s pressure limit for system planning. VIAIR specifies steel with a black powder-coat for corrosion resistance; at 20.5 inches long and 11.5 pounds, the tank’s dimensions and weight are practical inputs for choosing a mounting location.
- Five-gallon capacity
- Two 3/8-inch and two 1/4-inch NPT ports
- 150 PSI maximum working pressure
- Steel tank with corrosion-resistant powder coating
- The 150 PSI maximum working pressure is lower than tanks listed at 200 PSI.
Skip it if you require a 200 PSI-rated reservoir; this VIAIR tank is specified for a 150 PSI maximum.
This VIAIR reservoir fits truck builders who value mixed NPT port sizes and need five gallons at a 150 PSI ceiling. Check that the pressure limit and 20.5-inch length suit the intended system.

7. EVIL ENERGY 2.5-Gallon Kit
- Compatible with Vehicle Type: Truck, Passenger Car, Motorcycle, Van, UTV…
Best for: Complete 2.5-gallon kit buyers.
Why it ranks #7: The 2.5-gallon kit is listed for trucks and includes a drain valve, air hose, mounting hardware, and a 200 PSI rating.
A drain valve, air hose, thread-seal tape, and mounting hardware come with EVIL ENERGY’s 2.5-gallon tank, giving truck owners several installation components in one kit. Its 200 PSI rating and six ports suit a range of listed pneumatic uses, including air horns, tire inflation, and suspension systems.
The 2.5-gallon reservoir offers a smaller stated capacity than larger tanks, which can help buyers planning around a more compact air-storage setup. Six ports provide connection options, and the included hose, drain valve, seal tape, and mounting hardware supply several parts needed for installation. The listing specifies 200 PSI and 12 volts; professional installation skills are required, and the instructions recommend draining accumulated water weekly, so routine maintenance belongs in the ownership plan.
- 2.5-gallon tank rated to 200 PSI
- Six ports for connection options
- Kit includes drain valve, hose, and mounting hardware
- Thread-seal tape included
- Professional installation skills are required, and the tank needs weekly water draining.
Skip it if you want a tank without a stated weekly drain routine; this kit recommends draining water once a week.
Choose this kit if your truck build calls for a 2.5-gallon reservoir, six ports, and included installation components. It fits buyers prepared for professional installation and the listed weekly water-draining maintenance.

8. ZHSYMX 5-Gallon Tank
- Compatible with Vehicle Type: Passenger Car, Truck
Best for: Six-port onboard-air builders.
Why it ranks #8: This lightweight aluminum 5-gallon reservoir is listed for trucks and has six ports, but the supplied details do not state a pressure rating.
Six ports give this ZHSYMX receiver a practical connection spread for truck air horns and other onboard-air applications. Its five-gallon capacity provides a substantial stored-air reserve, while the aluminum construction keeps the tank lightweight for installation where a steel reservoir’s weight may be less suitable.
The five-gallon size supplies stored air for compatible horns or onboard systems, and six ports give an installer multiple connection points for arranging those components. Aluminum construction and an anti-corrosion coating support use in vehicle environments, while the stated NPT 1/4 threaded size identifies the connection standard to plan around. The manufacturer describes the tank as lightweight and portable and says installation can take a few minutes; actual setup still depends on the vehicle and system layout.
- Five-gallon air storage capacity
- Six ports for system connections
- Aluminum tank with anti-corrosion coating
- NPT 1/4 threaded connections
- All six ports use NPT 1/4 threading, which may not suit systems requiring larger ports.
Skip it if you need larger threaded connections; this tank’s listed NPT 1/4 ports may not match your plumbing.
Truck owners assembling an air-horn or onboard-air system can use this five-gallon, six-port aluminum reservoir where NPT 1/4 connections fit the plumbing plan. Check available mounting space and connection requirements before choosing it.

9. HornBlasters 3-Gallon Tank
- Material Type: Alloy Steel
- Weight: 6.06 kg
- Compatible with Vehicle Type: Car, Truck, Motorcycle, UTV, ATV, etc.
Best for: Mixed-port three-gallon systems.
Why it ranks #9: Its powder-coated steel 3-gallon tank supports truck-compatible horn, suspension, and onboard-air applications, with seven ports of two stated sizes.
Two 1/2-inch NPT ports and five 1/4-inch NPT ports give this three-gallon HornBlasters tank a varied connection layout for truck air systems. Its steel construction and powder-coated finish are specified for durability and resistance to impact and corrosion, while the capacity supports horns, suspension, or onboard-air applications.
Three gallons provides a smaller reserve than five-gallon tanks, which can suit a build where available space or the desired air volume favors a more compact reservoir. The two larger and five smaller NPT ports let a builder plan different connection sizes across the system. Alloy steel and the black powdercoat are listed for strength and corrosion resistance, and mounting hardware is included. Check the intended plumbing against the exact port mix before choosing the tank.
- Three-gallon capacity
- Two 1/2-inch and five 1/4-inch NPT ports
- Steel construction with powder-coated finish
- Mounting hardware included
- Three gallons offers less stored-air capacity than a five-gallon tank.
Skip it if you need five gallons of storage; this HornBlasters tank holds three gallons.
Choose this for a truck build needing three gallons and a mix of 1/2-inch and 1/4-inch NPT connections. It supports listed horn, suspension, and onboard-air uses, with capacity as the key boundary.

Listed on Amazon as: HornBlasters 3-Gallon (11.35 Liters) 7 Port Air Tank – Powdercoat Finish – Two 1/2" NPT & Five 1/4" NPT Ports
View on AmazonWhy it ranks #10: This compact aluminum tank has five 1/4-inch NPT ports and welded mounting brackets, but its supplied details do not establish truck fit or pressure rating.
Five 1/4-inch NPT ports and welded mounting brackets make this 1.6-gallon CNWZYMX tank suitable for compact, multi-device onboard-air layouts. Its listed dimensions are 15.75 by 7.1 by 8.46 inches, and the 3.61-pound weight can ease handling when positioning the aluminum reservoir inside a vehicle.
The five ports allow simultaneous connections for multiple devices, while the welded pair of mounting brackets gives installers built-in points for securing the tank inside a vehicle. At 1.6 gallons, its capacity is suited to buyers who prioritize a smaller reservoir rather than a high-volume reserve. The 15.75-inch length and listed 3.61-pound weight help with placement planning, and all five ports use 1/4-inch NPT, an important constraint when matching fittings and connected equipment.
- 1.6-gallon air storage capacity
- Five 1/4-inch NPT ports
- Welded pair of mounting brackets
- Listed dimensions are 15.75 by 7.1 by 8.46 inches
- Its 1.6-gallon capacity is limited for buyers seeking a large air reserve.
Skip it if you need a large stored-air reserve; this tank holds 1.6 gallons rather than a larger capacity.
This tank suits truck owners fitting a compact onboard-air setup with several devices and 1/4-inch NPT connections. Its five ports and welded brackets help with layout, but its 1.6-gallon capacity sets the storage boundary.

View on AmazonAvoid confusing an air reservoir with an air-brake replacement
An air reservoir for horns or suspension is not automatically a suitable replacement for a truck’s air-brake tank. Mytee Products Twin Chamber Tank is specifically described as an air-brake reservoir and lists Peterbilt OEM replacement numbers, a 2,267-cubic-inch capacity, seven ports, and alloy-steel construction. By contrast, the other listings mainly describe air horns, air suspension, onboard air, or air tools.
Their general truck compatibility does not establish brake-system compatibility. Before replacing a brake tank, match the truck’s required part number, chamber arrangement, dimensions, port count, thread type, and pressure requirements; the listing details alone may not confirm every fitment.
For accessory systems, choose a tank based on the equipment and plumbing it must serve rather than assuming that a larger reservoir can substitute for a brake-specific component.
How to Choose a Truck Air Tank
Capacity and intended use
Choose capacity according to the air equipment you plan to supply, and do not assume gallons alone establish system performance. Listed options range from CNWZYMX 1.6-Gallon Tank and EVIL ENERGY 2.5-Gallon Kit to Vixen Air 6 Gallon Tank and STAYTOP 8 Gallon Tank. Several 3- and 5-gallon models sit between those ends.
A compact tank may suit a constrained installation or a smaller onboard-air setup, while a larger reservoir may better match buyers seeking more stored air for horns, suspension, or tools. Capacity does not confirm how quickly a system replenishes air, so consider the compressor and air demand as well; those specifications are not supplied for every product.
Pressure rating and system match
Check that the stated maximum working pressure meets the requirements of the equipment and system you intend to use. STAYTOP 8 Gallon Tank, Vixen Air 6 Gallon Tank, Vixen Horns VXT5000, and EVIL ENERGY 2.5-Gallon Kit list ratings of 200 PSI, while VIAIR 91050 Tank lists a 150 PSI maximum. Some other product details do not provide a pressure rating, so do not infer one from capacity or construction.
The 200 PSI options may fit buyers whose compatible setup calls for that stated rating; the VIAIR tank suits a system designed around its 150 PSI limit. For a truck air-brake application, confirm the vehicle’s actual requirements and part fitment rather than relying on a general-purpose tank rating.
Ports, fittings, and included hardware
Match port sizes and counts to your plumbing, and check whether the tank includes the installation parts you need. Vixen Air 6 Gallon Tank lists nine ports: four 1/2-inch, two 3/8-inch, and three 1/4-inch NPT. VIAIR 91050 Tank has two 3/8-inch and two 1/4-inch NPT ports, while ZHSYMX 5-Gallon Tank lists six ports with 1/4-inch NPT threading.
Vixen Horns VXT5000 includes a gauge, pressure switch, valves, fittings, hose, and sealant; other tanks may include only mounting hardware or the tank itself. Buyers connecting multiple devices may prefer more ports, while anyone replacing existing plumbing should prioritize matching thread sizes and confirming the port arrangement.
Which truck air tank should you choose?
For a versatile air-suspension or train-horn setup, choose Vixen Air 6 Gallon Tank: it combines a 200 PSI rating with nine mixed-size ports. If you need the most stated storage capacity for a general-purpose truck system, STAYTOP 8 Gallon Tank offers 8 gallons and a 200 PSI rating. For a kit that supplies useful controls and fittings, Vixen Horns VXT5000 includes a gauge, pressure switch, valves, and hose.

Frequently Asked Questions
How do I confirm an air tank will fit my truck’s mounting location and plumbing?
Check the available mounting space against the tank’s listed dimensions, then compare its port count, thread type, and port sizes with your plumbing. Also confirm that the mounting arrangement and installation requirements suit your truck. If the product listing does not provide enough detail, contact the seller or a qualified installer before ordering.
What maintenance does a truck air tank need to limit moisture and corrosion?
Follow the tank manufacturer’s maintenance instructions, and check the tank and connections regularly for moisture, corrosion, leaks, or damage. Use the listed drain or drain valve as directed to remove accumulated moisture. Do not assume every tank has the same drainage or inspection requirements; consult a qualified technician if you find damage or are unsure how to service it.
How can I tell whether a tank is suitable for my truck’s air-brake system?
Verify that the tank is specified for your truck’s air-brake application and that its pressure rating, capacity, ports, dimensions, and connections match the vehicle’s requirements. A general-purpose air tank is not automatically an air-brake replacement. For a replacement, check applicable OEM numbers against your truck and have a qualified technician confirm suitability before installation.
How should I compare port layouts when choosing a tank?
Match the tank’s port count, locations, thread type, and sizes to the fittings and plumbing your setup requires. The listings include different layouts, such as four-port and seven-port tanks, and some specify mixed port sizes. Confirm that the listed details suit your installation; do not rely on port count alone.
How much tank capacity should I choose for a truck setup?
Choose capacity based on the requirements of your air system and the space available for installation. The listed options range from 1.6 to 8 gallons, but the titles alone do not establish which size is right for a particular truck. Check the equipment requirements and confirm fitment before selecting a tank.
Final Words
For a versatile air-suspension or train-horn setup, the Vixen Air 6 Gallon Tank stands out for its stated 200 PSI rating and nine mixed-size ports. Choose the STAYTOP 8 Gallon Tank if stated capacity is your priority, or the Mytee Products Twin Chamber Tank for a Peterbilt air-brake replacement after verifying OEM numbers. Before ordering any option, confirm pressure, port threads, dimensions, mounting, and installation requirements.
