When you manage a fleet that comprises light to heavy trucks and trailers, commercial vehicles, and specialty vehicles, it takes a lot of hard work to ensure that every part and system of these rigs work at peak efficiency. While you can invest in automation and an advanced fleet tracking system to keep tabs on every vehicle's movement and service appointments, you still need to fully grasp the true mechanics of important vehicle systems. A thorough understanding of the ins and outs of your ride or machine helps you make sound and informed decisions regarding your fleet.

For your big rig's pneumatic system needs, go only with the best—APSCO. This industry leader was founded in 1964, and since then, it has been supplying the mobile, automotive, and truck equipment markets with best-in-class pneumatic cylinders, valves, actuators, and controls. Backed by its over five decades of industry experience, innovation, and commitment to customer service, APSCO has cemented its position as an expert on air power. The company has also established its Winter-Fab division, which provides the pipeline, oilfield, and mobile equipment industries with turn-key precision metal fabrication services.

Headquartered in Tulsa, Oklahoma, the Air Power Systems Company (APSCO) Inc. is constantly evolving to address the varying needs of customers. It delivers innovative solutions to address the challenges of the industry as well as various application requirements. APSCO takes pride in being awarded with ISO 9001:2001 certification in 2004. The brand upholds its quality program and is now ISO 9001:2015 certified. All APSCO products are rigorously tested to ensure safe and reliable APSCO products.


APSCO's engineering department works in a collaborative set up to create new products from different creative minds. All APSCO parts are crafted using state-of-the-art equipment and modern design tools to ensure high-level manufacturing consistency. The brand's engineers make use of computer-controlled CNC machines for precision machining. These parts are then assembled by hand, rigorously tested, and subjected to an excellent quality control process. They are also tested for ease of installation and reparability.

APSCO parts are commonly found in various end markets, including oil and gas, construction, fluid power, waste and recycling, utility, and snow and ice removal. The company's biggest market is the heavy-duty dump truck and trailer. With its recent acquisitions, including the Minnesota-based STAC Inc., APSCO broadens its horizon by offering an industry-leading range of hydraulic solutions. This wide range of APSCO parts helped make the brand a market leader in OEM and aftermarket or replacement parts.


APSCO provides the industry with well-engineered generic consoles designed for end dump truck/trailer applications. These consoles are offered in various configurations and options to regulate the hoist cylinder and activate the truck's PTO. Among the standard features of these consoles are:

  • stainless-steel lid with laser-stamped label
  • steel base with powder-coating and access panel

Fleet managers can also work with APSCO to develop a console that's tailored to meet specific application requirements and personal preferences. The company's engineering team will customize a console that will help bring value to customers and savings to business operations. The common features of APSCO consoles include:

  • tailgate air control valves
  • warning lights
  • openings for a tarp switch
  • plugged openings for extra rocker switches or air control valves.


With their compact construction, APSCO actuators give weight savings without shortchanging customers with meager performance. These air actuators are specifically designed to regulate the operation of dump pumps or the opening and closing of hydraulic valves. APSCO's metering air actuators are economical alternatives to cable controls. They allow customers like you to save on labor and installation by eliminating maintenance and service issues common with cable controls.

The brand's DM series air actuators are available with or without metering. They have no exposed moving components, so they offer long years of service-free operation. These actuators are also outfitted with non-binding technology to ensure excellent performance and functionality. With simple three-step installation, these actuators can start doing their job in no time.


APSCO, from the get-go, has been designing and manufacturing products for the mobile equipment and heavy truck industries. With APSCO's cylinders, operators and fleet managers can have peace of mind knowing that the cylinder they will install can withstand harsh environments and applications.

Tailgate Cylinders

Most tailgate locking applications, at present, require a dependable and fast latch. This is what drives APSCO to develop best-in-class tailgate cylinders and latch kits that guarantee fast and reliable latching or unlatching of your truck's tailgate. The APSCO tailgate latch cylinders are available in many different bores and strokes to provide units that fit almost any type of trailer or truck body. These cylinders feature high tensile steel rods with corrosion-resistant plating. To make the installation of these cylinders easy and efficient, APSCO also carries compatible valves and fitting kits.

Hi-Lift Series

Composed of lightweight standard, twin, and round cylinders, the components in the HighLift Series features corrosion-resistant, high tensile steel rods. Standard APSCO air cylinders are ideal solutions for the high lift tailgate need of your dump body or dump trailer. They come with standard rod wipers and bearing blocks on longer strokes. Designed for dump bodies with higher gates and sides, APSCO's twin high lift cylinder delivers the force needed for taller gates while meeting DOT regulations. Round cylinders, on the other hand, are made to help lower the weight of the trailer and body. Their versatile, innovative design eliminates traditional tie rods and end caps and provides up to 60% weight savings.


APSCO engineers are backed by their thorough understanding of various applications and harsh operating environments, making this brand the first and only choice among truckers, fleet operators, and mechanics. APSCO provides the market with a variety of kits for easy servicing and maintenance of your pneumatic system and other components. These include seal kits, repair kits, conversion kits, rod and pin kits, rebuild kits, tubing kits, bracket kits, and a lot more.

The winch kits from APSCO are made for specific winch designs and fitted with brake cylinders, clutch cylinders, tubing, controls, fitting, and necessary mounting hardware. Moreover, APSCO's PTO control kits are easy to install and easy to operate. Offered in two, three, and four positions, these kits come complete with a control valve, fittings, cylinder, tubing, and mounting hardware. This company also offers clutch control kits that allow positive control of the vehicle clutch in remote locations like the cab or bed side. These kits engage and disengage the vehicle clutch and are offered complete with a 3-Way control valve, spring return cylinder, tubing, and fittings.
