Alcoa225392 Stabilizer Extension Kit for 22.5 Wheel Center Hole H-2225 HE-392

Extensions were too long on the valve end. Had to machine them to access the tire pressure and/or inflation. The collar was too long and center pin too short. I regularly air down for driving on the beach. So they've been a pain. I must say they've been air tight and the stabilizers work well. Another point to mention, the threads on the extensions are poorly machined and have made a mess of the threads in my aluminum air downs. In short don't waste your money. You're just buying a whole lot of headaches.

I have these on my 2021 Georgetown 34M5 with 19.5 inch Alcoa Aluminum rims.

If you have metal valve stems you must make sure it is a straight shot to the extension and the stabilizer. You do not want to accidentally bend the valve stem. In my case they would not work because of this. Luckily, I had a set of braided flexible extenders to use with the stabilizers. While the stabilizers are a great idea, they are extremely difficult to install. Or I ordered the wrong ones. I heated them, put soap on them and finally got them in the wheel hole, but time will tell if they stay.

Just as described

These worked perfectly with my aluminum 22.5's.
