Checking and maintaining proper tire pressure is important for ensuring a safe, smooth ride and maximizing fuel economy, but it can be a real pain with dually tires. The Wheel Masters inflation kit takes the hassle out of checking air pressure and inflating your dual tires.


Two hoses extend the valve stem location of the inner tires to the outer wheels. This means no more crawling around on the ground or blindly reaching for the valve stem on the inner tire. Two 135-degree hoses are also included to make it easier to access the valve stems of the outer tires. And the stainless steel wrapping on the hoses helps prevent them from cracking or leaking.


Hub-Mount Installation

Inflation Hose Kit Hub Mount

The dually inflation kit is designed for steel or aluminum rear wheels with wheel liners.


  1. Install 2 of the included brackets on the hub of each outer wheel. Make sure to align the brackets with the valve stem and a hand hole.
  2. Attach the hoses with straight valve extenders to the valve stems on the inner tires.
  3. Attach the hoses with 135-degree-angled extenders to the valve stems on the outer tires.
  4. Run the hoses to the outer wheels and attach the hoses to the hub-mounted brackets.
  5. Screw on the valve caps.

Very slow leak over winter storage. Caught it before tires were damaged. May disconnect next off season. Its almost impossible to get the inner tires without these units so kinda stuck in the middle. Seems well built otherwise. 634878

Just received, fast shipping. Have not had chance to install but look like good quality product. Will be replacing some that are 5 years old and have slow leaking problem. 416646

The angled hose fitting DOES NOT fit 2017 F450 dually. It's not bent tight enough to fit in the hole in the wheel. I did use the straight hose and it's ok. 551369

Installation was relatively easy. Initially I thought I may need to remove the outer wheel assembly to access the inner dually. I was able to squeeze my fat hand through and thread the hose on without much of a fight. The stiff hoses are a little tough to manipulate into place to determine where to mount the brackets. I opted to drill my decorative axle cover and pop rivet them in place. I did foul up on one bracket though. The instructions stated for my Ford to pop rivet from the inside. Obviously this is to give more surface area on the plastic cover. I drilled the last bracket holes without paying attention and one hole was too close to the lug attaching point. No way to get the rivet gun on that one. Had to install it from the outside. If it gives out I'll re-do it with a back up washer. Just pay attention when/if you drill yours. MAKE SURE OF YOUR CLEARANCE! So far I like these things! 445314

Makes checking air pressures very easy. Having a class B on a Sprinter chassis, the outside tires were extremely difficult to monitor...now easily handled. Not difficult to install. 522314

The only reason I did not give a 5 star review is I had to make a slight modification to the outter wheel hoses. On my 2017 Ford F-450, the 135-degree bend did not allow me to connect the hose to the existing valve stem. I used a vise and carefully adjusted the bend to approx 140 degrees on each hose and they worked fine. I also recommend you use longer pop rivets and use backers on them to ensure long term durability of the mount. Now, the the kit itself: I really like it. After install, I was able to check the tire pressure and easily inflate both sets of duals to the recommended 80 psi. With this kit, maintain proper air pressure is going to be much easier. I expect a long service life from this kit and I'm very happy with the purchase. 734196

2016 F350 duallie. This air valve extension kit solved my issue. It was a battle getting air into my inners through the stock stems. I bought different chucks and a couple worked... ok. OK doesn't cut it in the middle of winter in NH so I wanted a good solution. This was it. Valves are right up front for easy access. Doesn't look half bad either. You would think the downside is that there is no balancing valve like pricier units. I have to fill each tire individually. Not really a bad thing since I run the inners a little lower when the truck is empty, most of the time. Bump them up even with the outers when hauling. Couldn't do that with a balancing valve. 747480

    I suggest the Wheel Masters 4-Hose Inflation Kit # WM8208 for your 19-1/2-inch dually wheels with wheel covers. This kit is shown on the linked page along with our other inflation kits. I also linked a review video so you can see more about the components in this kit.

  • Tire Valve Extenders for 2017 Winnebago View 24J Class C Motorhome
    I linked our main page for valve extenders so you can see all the items we carry but since your Winnie Class C has dual steel rear wheels I lean toward the Wheel Masters kit # WM8029135. These have a 135-degree bend and are USA-made with nickel-over-brass construction. Of course, you're free to use whatever length and bend works best for you. There are lots of different opinions on this subject to be found on Winnie forums and you might care to review some of those.

    If you have wheel liners then you want to use the 135 degree bend kit part # WM8001-135 but if you have wheel covers then you need the 90 degree bend kit part # WM8208 instead. Attached are demonstration videos of each for you to reference.

  • Wheel Masters 4-Hose Inflation Kit for 16 Inch Tires With Wheel Liners
    I recommend the Wheel Master 4-Hose Inflation Kit part # WM8001-135 for 16 inch dually wheels. The Wheel Master hoses install with your simulators and are designed with a 135 degree angle to make accessing the valve stems on the inner tire easier. I have attached a video for your reference.

    Yes, the Wheel Masters 4-Hose Inflation Kit # WM8001-135 that you referenced does fit your 2018 Ford F-450 dually. I checked the wheel size of your vehicle (19-1/2 inch diameter) and found that it uses the correct size to use this kit.

  • Recommended Valve Stem Extension for Thor 24F Motor Coach
    I looked up the wheel size of your Thor Motor Coach 24F and it uses 225/75-16 dually wheels like what the Wheel Masters kit part # WM8001-135 you referenced is designed to fit, but I'd recommend going with an airless kit like the part # WM82082 instead. The airless kits mean that the hose doesn't have any air in the line when it's not inflating/deflating. This means the kit wouldn't leak air if it was somehow damaged.

  • Where is 135-Degree Hose Bend on Wheel Masters 4-Hose Inflation Kit
    The Wheel Masters 4-Hose Inflation Kit # WM8001-135 referenced in your question does include two stainless-steel-wrapped hoses with a 135-degree bend. These will allow for easier access to the valve stems of the outer tires on your vehicle. I have attached an image with this feature highlighted that you can take a look at. This inflation kit will relocate the inner tire's valve stem to the outer wheel and extend the valve stem on the outer tire. A total of 4 hoses are included.

  • Wheelmaster Valve Stem Extenders that are Airless
    The most similar airless style of Wheel Master inflation kit we offer for 16" to 19-1/2" dually setups is the part # WM82082 which instead of 135 degree bends has 90 degree bends. Airless means that the extenders do not hold any air pressure in them. The part # WM8001-135 that you referenced is not airless. If your 2015 Coachman Freelander on a 4500 Chevy chassis has wheels that have wheel covers then the part # WM82082 will fit.

  • WDo Tires Need to be Balanced when adding the Wheel Masters 4-Hose Inflation Kit
    When installing the Wheel Masters 4-Hose Inflation Kit part # WM8001-135 or any other of the Wheel Masters Extenders i have never ran into an issue of the tires needing to be re balanced. They are very lightweight and designed not to effect the balance of the tires. If for some reason you should feel any additional vibrations when driving after installation you can have them balanced but in all cases I have seen it is not an issue.

  • Best Wheel Master Valve Extender on a 2014 Ford F-350 Dually
    For your 2014 Ford F-250/350 Super Duty you will want to use Wheel Masters 4-Hose Inflation Kit part # WM8001. The bend on the Wheel Masters 4-Hose Inflation Kit part # WM8001-135 causes the hoses to be in contact with your rim as soon as it comes off the valve stem. I like the decision to get these.

    It sounds to me like either Wheel Master Inflation Kit can work for you. It more depends on how you wish for them to be installed and what will work best for your wheels.

If you want to include the 45-degree valve extenders with the # WM8001-135 you can add them using # WM8029. The other advantage of the # WM82082 kit is that it is airless so if the...
