  • After a few hours of off-roading on a perfect summer day, you don't want to let deflated tires slow you down. Heat and rough terrain might cause your tires to lose pressure, costing you a reduction in control and MPG, but with a quick stop to make use of your portable air, you can get back out there with hardly any delay. When you have an onboard air system, you can easily fill up those saggy tires and still have enough compressed air to run air tools and dust yourself off. If you're not worried about filling your tires, you can get a smaller unit to make use of air lockers, air horns, and minor pneumatic needs, perfect for camping and small repairs.

    Using Your On Board Air System
     
    A variety of air systems are available including the maximum power viair onboard air compressor to conveniently-sized portable units, depending on if you need to apply a great deal of working pressure or just need light air power. Many OBA systems are easy to install and fit in tight spaces, leaving plenty of room for other accessories and upgrades. The best part of having your own OBA system is never having to worry about where your compressed air is going to come from. Low tires and air-powered equipment no longer require a trip to the nearest air pump.

    The Right Air for You
    Finding the right air unit need not be daunting. 4 Wheel Parts has a wide selection of onboard air, so you can find the right size, power level and convenience for your vehicle at the right price. Whether you're using a lot of pressure to fill tires and run air tools, or if you just need a boost of air for air lockers, 4WheelParts.com has the OBA system you need. The systems available include everything you need from hoses to valves so it's easy to use your new air system without the hassle of finding spare parts.
