Circuit Performance Chrome Bolt-in Flush Mount Valve Stems (Set of 4)

Very good, clean looking

Fits good no leaks

I used these because my three-piece wheels use outer lips as inner barrels (don't ask). These allow for a flush fit on the inside and a clean look on the outside. So far all of them are holding air. We'll see how the finish holds up to wheel cleaners etc. So far no issues.

Great

I do like the quality but no instructions or at least a diagram of what parts go where. I was able to figure it out but still it would be nice to have some sort of explanation of what goes where.

After buying a set of Neuspeed lightweight wheels I was looking to add a nice touch to them. I've never had flush mount valve stems and found these after a little searching. They are constructed of good quality materials and installed easily. I've only had them on the car for a couple days so I'll have to update long term performance. They add a seamless look to the wheel that doesn't subtract from the wheel design. Satisfied customer here!

I came across these after i ripped a regular valve stem off with a tree limb. Easy to install, and easy to use, very happy.

I'm a mechanic for Toyota and didnt find it hard to install these the only problem I have with them is the stem in which you use to fill your tire with air. It bent the first time using it so I had to straighten it multiple times for it to be useable then when it was useable all the air gauges I used would leak air because the needle was too long after grinding about an 1/8 of and inch or more off it works correctly you need to make the stem valve out of something a little stronger and work on getting it the right size after that it's a great product

Was exactly whatbit was supposed to be
