GMC 3500 DRW

[yellow_dog]

Anyone make any modifications to the tire valves on a GMC / Chevy 3500 DRW? Outer and inner wheel I find are difficult to air up and check do the location of valves on aluminum wheels. I am planning on adding extensions to inner wheels, but outer valve faces inward making access somewhat awkward.

I have a few of these but they're not the right angle to go on the valve stems.

Have to wedge my meat hook sausage finger hands into the hole with a standard chuck to get a straight shot on the stems.

Absolutely, I've tried three different extensions, and they all leaked eventually. One leaked immediately, and the other two took 6 months, and a year...but they all leaked.

I put 4" curved metal extensions on the inner rear wheel. They are short enough that they don't vibrate against the wheel. The caps are close to the rim and difficult for me to take off so, I changed the caps on the other valve stems to a longer cap I can easily take off to check the tire pressure or add air. After 2 years they haven't leaked.

Howdy!

Thanks.

I have a couple of those and still can’t connect to air it up.

I prefer the straight shaft for dinner, obviously rear angle for outer. Some rims have really small openings, you can't get the angled inner dual to work. I have this issue with my IHC. Did not have the issue with my 3500 series dually s. I do admit, the straight inner works better.

Yep the above is the trick.

I’m having a even harder time with my rear DRW now that I have added TPMS. I installed flow through TPMS thinking I would be able to access them and now it is even worse.
