Every good air suspension kit should have a high quality air tank to store the air produced by the air pumps. Most air tanks on the market are going to require you to run valves externally, meaning you will have more to deal with during install and more plumbing that will be visible. Our patented ENDO-VT™ valve integrated air tank provides a cleaner install by having the valves integrated into the air tank. This allows for quicker installs and an overall nicer presentation in your trunk, truck bed, or anywhere else you choose to mount your tank. The ENDO-VT also represents AccuAir’s next generation of solenoid valve technology that includes VFC™ (variable flow control) in addition to D.O.T. approved fully filtered and rebuildable FFPTC (fully-filtered push-to-connect) fittings. About ENDO Tanks AccuAir’s ENDO-Tank product line is the result of years of engineering accomplishments and represents the largest leap forward in air tank technology for 100 years. The system allows tanks to be built modularly with all precision machined aluminum components and with a bolted construction. As a result, these tanks are weld-free and leak-free. Ports are machined directly into the solid aluminum body and are flush with the outside of the tank. Modular construction allows the end-caps to be removed allowing for never before imagined feature combinations to go inside the tank. These tanks are offered in raw aluminum. What Size Tank Do I Need For Air Suspension? One of the most common questions surrounding air suspension air tanks is “what size tank do I need for my air suspension kit?” Most air suspension systems are going to utilize a 3 gallon or 5 gallon air tank. The size you will need will depend on how often you plan on using your air suspension and the type/quantity of air compressor you are using. If you plan on airing out every chance you get, you may want to get a 5 gallon tank to store more air for quicker operation. Our ENDO tanks are offered in 3 gallon and 5 gallon options. The 5 gallon ENDO air suspension tank dimensions are: Length: 29.312" Height: 6.625" Diameter: 6.625" The 3 gallon ENDO air suspension tank dimensions are: Length: 18.312" Height: 6.625" Diameter: 6.625" Installation Guide Mounting Template With Bend Line (3 Gallon Tank) Mounting Template Without Bend Line (3 Gallon Tank) Mounting Template With Bend Line (5 Gallon Tank) Mounting Template Without Bend Line (5 Gallon Tank) Plug Diagram
