These don't fit our 2010 F-350. The bends at the ends of the straps assume your rims are stamped or pressed, and have an edge on their insides. Ours don't: our rims are pretty solid and the holes have 90-ish degree angles inside and out. I had to use pliers to flatten the strap ends so they'd go in the holes in the rim. Nothing secures them once there. So I reached around the back of the outside tires to try to bend the straps' ends to fit, but that's not a sure thing. Any vehicle that has similar rims will have the same fitment problem.

We take our truck camper off road on occasion. The locknut *should* keep the straps in place. However, "should" isn't the best feeling when RVing.

I reached out to Wheel Masters about your installation. They noted that this kit is designed for steel wheels without any wheel covers, liners, or hubcaps. For a wheel like yours, the # WM8002

kit is a better solution.

Work very well on rear inside dually tires. Mount to outside rim to allow easy access to inside tire for pressure test or tire monitor.




by:

This valve stem extension setup was on my motor home duals when I bought the coach and worked well, but only on one tire per side. I wanted the same setup on all four rear tires but had trouble finding them. Someone on a RV forum said to try etrailer and their they were! They are simple and light enough not to affect tire balance and work like a charm. This is one year later and no regrets.


Comments
Still working fine, they did expose a weakness in my valve stems. One tire was low and it turned out to be the valve stem didnt like to be pulled at an angle. The fix was upgrading my valve stems.

I used these on my 2017 Ram 3500 for the inside rear wheels. They work great.




by:

Installed on valve stem with minimal air loss. Afterwards was easily able to inflate the inner dual tire and check the pressure.


Comments

These valve extensions were very easy to screw on. No tools necessary.
The service from etrailer is always fast. They shipped out the same day the order was placed.




by:

I have always found the etrailer web site helpful and my most recent order is exactly what I wanted and as represented by the company.




by:

Order was delayed since not in stock but I eventually got what I needed as described. Would have been good to know they were on back order or not available for immediate shipping. That way if I needed them ASAP I could have looked elsewhere.
