Circuit PerformanceVS33 Shorty Black Bolt-in Valve Stems (Set of 4)

They work, good quality. QC is a little off, I've bought two packs and the second was missing one of the lock nuts.

I prefer these over the WEDS stems because there are no visible fasteners on the outside of the wheel. As well they are quite short and the aluminum caps are nicely machined.I bought a second set for my 4runner because they sit so low in the rim that they'll be much safer offroad.I only put 4 stars foe durability because I haven'thad the 4runner off the pavement since adding them. I have no doubt they'll be great.

Highly recommend to change every time you change your tires. I thought being steel and for the price they would last longer. They last about the same as a tire. I've had several leak. But they do look clean on custom rims

Although the outside of the stem is low profile, it makes up for the length inside the rim. The stem could easily get hit by the install of the tire damaging the tire or valve stem. Also, if you have a low profile tire, these could actually puncture the tire if you have low psi or hit a bad bump. My tire installer would not install these for me.

These are fantastic for the money. Only gripe is that even after tightening to a typical specification for metal stems, upon tightening the caps with a screwdriver style bit driver, they rotate in the hole. No leaks or anything but it leaves m a bit unsettled.
