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.

  • Recommended Valve Extender and Suspension Enhancement For 2018 Ram 3500 Dually 4x4
    The Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88295 is the best choice in air bags to help stabilize your load. These air bags are going to reduce the strain on your rear suspension. They're going to help increase safety and compensate for uneven loads. They allow you to level your vehicle front to back and help maintain safe headlight aim, and they adjust independently for side to side leveling of off center loads, and it's really going to help improve steering and braking...

  • Will The Wheel Masters 4-Hose Inflation Kit # WM8001-135 Fit A 2018 Winnebago Vista 29VE
    Hey Chris, From what I can find your 2018 Winnebago Vista 29VE has 19.5" wheels so the Wheel Masters 4-Hose Inflation Kit # WM8001-135 would work. Based on the photo the 135 degree bend is likely going to be the best fit but you might have to play around with it to get it perfect. These inflation kits can easily be installed at your home so you aren't wasting money on labor. I've attached a short video below where Dave will walk you through the installation process.

  • Valve Stem Extender Fitment For A 2023 Ram 4500
    From the connection point to the end of the bend in the Wheel Masters 4-Hose Inflation Kit # WM8001-135 is approximately 1-1/2" in length. You could try sticking a tape measure in there and measuring out 1-1/2" at a 135 degree angle to see if it will clear the handhole in your wheels.

  • 2020 GMC Sierra 3500 Valve Stem Extender Recommendation
    I recommend checking out the Wheel Masters 4-Hose Inflation Kit # WM8001-135 which is designed for 16" to 19-1/2" Dually wheels. These kits are universal fits so you might need to move some stuff around to get them to fit correctly.

  • How to Easily Access Thor Challenger Dually Valve Stems for TPMS Kit
    We have some kits like the Wheel Masters 4-Hose Inflation Kit # WM8001-135 that essentially extend the valve stems out so they're easier to access, but we don't do any kind of work on valve stems. These are compatible with a TPMS kit as well so you'll still be able to make this work like you're wanting to.

  • 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. They can save a lot of headaches trying to get to that rear stem with standard air chucks. I've attached a video David did on them to give you a little more insight into the installation...

  • Using TPMS Flow Through Sensors And Valve Extenders On A 2024 Ford F-450
    Hi John, TST Flow Through Sensors # TST-507-FT-S2 are approximately 2-1/8" long so they do add a bit to the overall length of the coming from the valve. TST likely told you that the sensor has to be directly after the valve to avoid any movement with the sensor that could damage it or the valve and to help prevent any false readings. With valve extenders like the Wheel Masters # WM8001-135 you'll be able to tuck the excess cable up since you'd be mounting the end of the extender to the...

  • Valve Extenders for Outer Dual Rear Tires
    The 45-degree bend valve extenders like the Wheel Masters # WM8029 that you referenced are usually the best option for the outer wheel on dually wheel setups. We do also have 135-degree bend extenders with part # WM8029135 if your particular wheels don't allow the 45-degree units to be a good fit. Another option you might consider is the Wheel Masters 4-Hose Inflation Kit # WM8001-135. This kit will let you relocate the inner tire's valve stem to the outer wheel while also extending the...

  • Recommended Valve Stem Extenders for E-450 Super Duty Chassis
    The 135 degree hoses are not offered separately from the Wheel Masters 4-Hose Inflation Kit unfortunately. I wish I could tell you exactly what you need but these are not vehicle specific parts, they are universal therefore up to the installer to determine compatibility. That said, the Wheel Masters 4-Hose Inflation Kit part # WM8001-135 is pretty common for dual axle motorhomes so they should work for you as well. They are compatible with TPMS.

  • Inflation Kit Installation on a 2018 GMC Yukon 3500 Dually
    The access to the GMC Yukon 3500 with dual wheels is so limited that to my knowledge we have not had anyone install the Wheel Masters 4-Hose Inflation Kit # WM8001-135 on one. The inflation kits are typically sized by wheel rather than vehicle specific. We do have the Wheel Masters 4-Hose Inflation Kit # WM8001 as well, which would have a 90 degree bend opposed to the 135 degree bend the # WM8001-135 has. These kits include the hardware. The bend you choose for the outer wheel really just...

  • Determining the Correct Valve Extenders For A 2018 Chevy Silverado 3500 High Country
    There unfortunately isn't a guide to tell us what the correct degree bend you'll need for easier access to the valve so you'll want to take a look at your valve stems to see how they're sitting and determine the route out to the front of the wheel. For most dual wheel applications the Wheel Masters 4-Hose Inflation Kit # WM8001-135 has been the best fit in my experience. This has a 135 degree bend but there's also a 90 degree option # WM8001 as well. Without really seeing how everything...

  • Recommended Method For Installing TPMS Sensors On Inner Dual Wheels
    The easiest way to install the TST TPMS for RVs # TST-507-FT-6-C on hard to reach dually valve stems would be to first install some valve extenders like the Wheel Masters 4-Hose Inflation Kit - 16" to 19-1/2" Dually - Hub Mount - 135-Degree Bend # WM8001-135. This would allow you to easily install or remove the sensors for charging without having to struggle every time.

Another way to go is the Wheel Masters 4-Hose Inflation Kit # WM8001-135. This kit will let you relocate the inner tire's valve stem to the outer wheel while also extending the valve stem on the outer tires.

This will allow you to mount the fill points near your hub center for much easier access. The front wheels will need the Wheel Masters Tire Pressure Valve Extenders # WM8029135.

  • 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.

There are different kits depending on how your valve stems are set up on your wheels on your RV.

    I do have options for you, but the Wheel Masters Inflation Kits are not vehicle specific parts. They are going to depend on the wheel set-up that you have. However, I can provide you with a couple of the most common options we typically see on the E-450. If you have wheel liners on your wheels then you want to use the 135 degree bend kit part # WM8001-135. If you have wheel covers on your wheels then you would want the 90 degree bend kit part # WM8208 instead. Both of these will fit wheels...

  • Recommended TPMS System and Valve Stem Extenders For a 2017 Winnebago Minnie Winnie M31K Ford E-450
    Yes, the Wheel Masters 4-Hose Inflation Kit # WM8001-135 will be the extenders you want for your 2017 Winnebago Minnie Winnie M31K on the Ford E-450 chassis. You should really consider using a system like the TST TPMS # TST-507-INT-6-C which uses internal sensors. This will give you the most accurate information about what is going on with the temperature inside the tires. With external sensors like the TPMS # TST-507-FT-6-C uses at the end of the extenders they will not give you an accurate...

  • 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.
