There are different top 10 or top 8 lists for this part, yet all the ones that made one list were not mentioned for sale at any of the stores we highlighted here. The only exception was pacific and it was listed on Amazon for sale but not in any of the auto parts stores above.

The best one will be the one that does the job for a long time. You have to be careful with the braided versions as they tend to leak more than other designs. They may be handy and easy to maneuver but their strength is another issue.

Are Valve Stem Extenders Safe?

The may issue we found was that they are safe unless the extenders are installed improperly. If they are, you may have some problems as you drive. Another issue that came up is that you may have to have the rubber valves replaced with metal ones or you may still have problems.

But those are not the only two issues you may have. If you use tire covers and they come off while you are driving, then those covers can break the longer extenders in half, etc. That means you would have to replace those extensions and check for any tire issues due to lost air.

The biggest issue will be leaking. Some extensions are known to leak a lot, like the braided kind, so you have to be careful Then if the extensions go beyond the rims, you may break them when you rub them against a curb.

What makes these extensions unsafe is the loss of air in your tires which will impact handling and performance.

How do You Install Valve Stem Extensions on a Dually?


The most difficult aspect of this task is reaching the cap on the installed tire valves. These valves can be hidden behind the rim and very hard to reach without using proper tools. You may not be able to get your fingers inside to unscrew the cap.

But once you get the cap off, you just reverse the process. If the extension is long enough, you may not need to use a tool to start the installation. Then use a pair of needle-nose pliers to tighten the extension up. Just do not over-tighten it.

Once the extension is in place, you attach the stabilizer to hold it in place.
