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

Installed on my charger due to caliper clearance issue and this solved the problem looked great and works wells.

These worked great on my new wheels that would not allow a standard valve stem.

But nothing holding the valve core in the filling extension. Tough to get the tire inflator to push the valve core without bending it. Nice idea, not ready for prime time.

Good product

Did exactly what I need them to do

The filler tube piece *looks* like it's threaded, but it's more currogated in texture, and only part of the tube has this texture. This makes it completely useless for the rims I was going to install these on. I off road, and oftentimes I lower my tire pressures while on the trail, then reinflate before hitting the highway. Both of my portable pumps have threaded fittings and screw onto the valve stem, and this obviously doesn't work with these. Will be returning these.A note to the manufacturer: You've already threaded the base of the filler tube in the correct thread... why didn't you thread the other end of it? I mean sure, the whole point is that it doesn't have a valve stem, and you're not putting little ducky valve stem caps on it, but it would be exponentially more useful if it was just threaded like every other valve stem.

Used to flip my banshee wheels worked great

Work okay, but filling air with the adapter became a real pain.After a few trips one tire always needed air, I pulled the tire to tighten the valve. Only after that did I find that it was cracked. Going to remove and replace with standard rubber valves.
