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

Great quality replacement to my old and crusty Regamaster valve stems. Very happy with the new ones.

I needed the shortest valve stem possible and these fit the bill perfectly

works great

Product arrived and looked good. Once I started installing them on the wheels I found that the treads on the nut holding it in place was slightly different from the body. When checking there is a lot of play when moving the nut up and down. Once installed it was even worse as the nuts started slipping from the treads. I don't recommend this item.

I installed one of these on my new wheels . It was just a little too short for my liking,so I purchased the VS43 valve stems from Circuit Performance. The VS43 version appears to be made from stainless steel. 👍

Its ok carefull not to strip threads there not very deep

I am really happy I found these. The install was very easy and fit great. Almost more importantly, they look really good. Valve stems are inherently ugly and these valve stems eliminated their pronounced appearance.

Looks GREAT, but BEWARE: you will probably need two packages of four (almost certainly) to do just four wheels. And there's more...You will probably need more than one package (more than four valve stems) because these valve stems are made from an extremely soft metal or alloy. My installer messed up two of these valve stems while trying to install a set of four. He forecasted this before he even tried, and he suggested that I find other valve stems instead, but he agreed to try installing them because I didn't want to go shopping again and I didn't want the usual rubber black stems that he had in stock.The exterior tip of the valve stem is not curved in any way, so in order to tighten the "first" nut inside the rim, you will need to put a tiny wrench on the decorative CAP. Then when you try to put the "second" nut on inside the rim - the lock nut - you will need to again put a tiny wrench on the decorative cap. Otherwise the whole assembly spins as you try to tighten an air-tight seal. An experienced installer who knows this ahead of time may still have a hard time installing these without damaging one or two of them in the process.But wait there's more. The fun is not done with this alloy. There is no coating on these valve stems. For example, you may have seen Enkei brand valve stems that are coated blue color. This coating would be corrosion inhibitor. If you leave these valve stems on a wheel for longer than a year or two, then you have a chance of mayhem. Things seize, and sometimes things leak. My installer showed me a couple of examples of similar valve stems that had to be "creatively removed". Imagine your tire is low on air, and you can't get your decorative cap off to put air in the tire. Well that's because the threads on the caps and stems corrode, and the caps fuse onto the valve stem. Decide to use a wrench to remove that cap? Alright decent idea but now you just mangled part of the head right off of the valve stem, and now either (A) the tire won't hold any air until you get a new valve stem because the valve came out when you busted the head off, or (B) the valve stem is mangled inside what's left of the head, but the valve is stuck. So in scenaro (B), the solution from there is to put a hole in your tire in order to deflate it. My installer showed me these old mangled valve stems.So which is a worse outcome - suddenly having a tire that won't hold air, or, getting to a shop to find out that they have to slash your tire before they can remove it to install a new valve stem?You can put anti-oxidation gel on the threads of the valve stem to keep the cap from fusing onto the valve stem, but use it VERY sparingly to avoid squishing it into your valve when you tighten the cap. It can be found in the Home Depot electrical aisle, and is known as "no-locks" (spelled NOALOX, which stands for No Aluminum Oxide), and also known as "Penetrox". Ask for the stuff to prevent oxidation on aluminum-to-aluminum electrical connections.All of this possible upcoming mayhem was so real to my installer that he insisted on giving me four grey plastic valve stem caps for free, instead of using the hex head metal caps that come with these valve stems. He said that he could not install the metal caps himself because it would be such terrible workmanship to let a customer leave the shop with them installed. He gave me the metal caps separately in a bag for if I dared to install them myself. I'll just use the grey plastic ones he gave me.So, I say four stars out of five. They hold air, and they look awesome, but, they came with quite a talking-to from the tire guy who installed them. The next time the tires get dismounted, then I'll be installing a new set of these valve stems. Luckily next time I'll only need one bag, because I still have two leftover from the first eight valve stems that I bought.
