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 90-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

  3. Attach the hoses with 90-degree-angled extenders to the valve stems on the outer tires.

Stainless-steel-wrapped hoses take the hassle out of inflating and checking the air pressure of tires on dual aluminum wheels. Kit is designed for aluminum rear wheels without wheel liners. Hardware included.


It was an exact replacement for the dual wheels on my 2009 Safari Cheetah motorhome.


The wheel master WM8110a valve stem extensions for hub mounting on my 22.5 dually's worked great. I was able to to install the valve stem brackets on huds with the supplied parts (pop rivets and SS brackets) without removing the wheel hub cap by using an offset electric drill. Complete kit and easy to install


A good product. My only suggestion is that stainless steel screws with Philips button heads and locking nuts be supplied rather than aluminum rivets. The screws are stronger and don't react with the stainless steel hub like aluminum will. I also slipped a nylon hose over the air hoses where they pass through the slot in the wheel to prevent chafing and eventual failure.


I was looking for stainless Steele’s braided valve extenders for our motorhome with a 3” 90 degree turned me find the perfect kit. The kit arrived after only a few days and each piece was a perfect match. Easy to install and now no more worries about tires losing air.

Thankyou Phyllis and etrailer!

Still working great!

Great product from etrailer as usual


Needed some vehicle specific valve extensions, wanted two day shipping . . . reasonable price, excellent packaging, shipping and even a call to let me know when they were shipping. As a 20 year veteran I find this to be one of the best companies I have ever dealt with. Highly recommend and I will be back, thank you . . .


One of the extenders with the 90-degree angle connector acted like it wasn't depressing the tire stem which made it hard to either add air to the tire or to obtain an accurate reading. I removed it for that reason. The other one seems fine


Didn’t end up using them. Did feel would work well for my application. Found valve extensions that work much better for me


These make life so much easier and are really essential with dual wheel setups.


Exactly what I needed for my 2004 Monaco Windsor Motorhome with 22.5 wheels.


Exact replacement for my Holiday Rambler Imperial


Great product and great knowledgeable staff. Professional and friendly.


The parts are just what I needed.Very happy with the product.


Worked as described. No leaks.


Installed easily and made checking or putting in air very easy.



looks good in the package, have not installed yet.


Excellent service and response.


Great service and product

  • Will 90 Degree Hose Work on Valve Stem Pointing to Inner Tire
    You will not need any type of special tool to install the Wheel Masters 4-Hose Inflation Kit # WM8110A and you will be able to use the 90 degree hose on the outer tire whose valve stem points to the inner tire. The reason for this is the flexibility of the the hoses; they are designed so that you can flex them if needed so you won't have an issue with the angle. I have added a link to a video of a similar inflation kit being installed which should help give you a good idea of the installation...

  • Availability of Valve Extenders for Inner Dual Wheels
    Most of the valve stem extenders we offer, such as the # WM8110A that you referenced, are 4-piece kits. But we do offer inner-wheel-only extender sets such as the Wheel Masters # WM80092. This kit features two 8-inch stainless extenders that mount on hand-hole brackets which are included. This kit fits inner dually wheels from 16 to 19-1/2-inches.

  • Actual Dimensions of Wheel Masters 4-Hose Dually Inflation Kits WM8001 and WM8110A
    The Wheel Masters 4-Hose Inflation Kit # WM8001 fits dually wheels from 16- to 19-1/2-inches. I went to our warehouse and pulled a kit to measure the actual length of the hoses. I also measured the similar kit # WM8110A which fits 22-inch aluminum duallys. In both kits the straight hose (without the right angle bend) measures 13-inches tip to tip. In kit # WM8001 the right-angle hose measures 10-inches from bend to tip; in kit # WM8110A the right-angle hose measures 14-inches from bend to tip.

  • Wheelmasters Inflation Kit that Fits 22 inch Diameter Wheels
    Wheelmaster does offer an inflation kit that was designed to fit 22 through 24 inch dually wheels with the part # WM8110A but the kit you mentioned would not fit as it is designed for smaller wheels.

  • Difference Between Wheelmasters Valve Stem Extenders # WM8110A and # WM8004
    The difference between the two kits is the type of wheel they are designed to fit. So since you have aluminum wheels without wheel liners you need the part # WM8110A which were designed for attaching to that specific wheel style. The part # WM8004 is for wheels with wheel liners and attach to them instead so the clips would not work for you.

  • Valve Stem Extenders for DRW 2022 Ford F-450 Super Duty
    I believe the 2022 Ford F-450 Super Duty has 19.5" wheels, verify this for your vehicle. I suggest the Wheel Masters 4-Hose Inflation Kit, # WM8001 which is for wheels up to 19.5".
