Crossfire Dual Tire Pressure Equalization System, 90 PSI, one per pkg. (CF90STABT)

I have a 2008 F450 with simulator wheel covers. Even though the company specifically states these are not made for wheels with simulators, I bought them anyway and figured I could make my own brackets if the ones that come with it wouldn't work. Installation on the first side took about an hour. To my delight, the supplied large bracket worked just fine. Most of the time was spent trying exactly where to position the outer wheel to get stem distances that would work for my specific installation (ended up being about 145° or two holes away). In my photo, the stems are indicated by red arrows with the rear stem being the left one. The only problem I ran into was that my simulators sit high at the hand holes. This meant the 180° fitting for the outer wheel wouldn't clear it. I carefully opened up the bend at the end of the hose enough to clear it (from 180° to about 135°) and it worked great - easy to open up with little force and no crimping or deformation of the tube. I'm guessing the tube is chrome or nickel over brass. The other side took about 15 minutes. Tightening the hoses to the stems was like building a ship in a bottle with a ½" wrench, or in my case, just like trying to air up the inner tire previously. I knew it was the last time I would have to stuff my hands in there so I was just fine. I'm looking forward to the safety and the convenience!!

If you don't have a tire pressure monitor already installed inside of your tire and you want to add an aftermarket monitor, you will need an adapter that goes on the air hoses to be able to install the sensors. They also make a flow through sensor on some models of tire monitors if ordered originally otherwise they cost more.

The hook on the braided hose was too sharp for my RV wheels. I called the Dual Dynamic guys and they were great. Apparently the hook has options. Should have purchased from the their website. They sent me two hoses with 90 degree hooks which should work. Unfortunately installing these with the Wheel Master covers will require modifying the mounting bracket. I'll also have to remove the outer tire. Not a fun thing.

Had to grind a little from bracket to fit. Fits well and works great for peace of mind

Do not buy!! Installed as instructed. Both units read 10 lbs. higher than actual pressure (measured by 2 known to be correct gauges. One unit had 15 lbs. per week air leak. I removed the suspected leaking unit and my air loss is about 1 psi. per 1-2 months which is normal. E-mailed, called Crossfire and have hade no response.

A little extra work to install on a duelee but well worth it.

We had purchased these for our 2005 Motorhome, but did not have them installed before we upgraded to a new motorhome. Camping World installed the Crossfires for us at no charge. Yay! Camping World in Springfield, MO--the best!

Piece of mind, every time I stop for gas.
