Review on C508 Rubber Valve Stem (100-Pack) - Topline by Larry Cho

No complaints. They were easy to install, all have worked so far and you can't beat the price. I later found 100 packs of different valves (25 of one type, 25 of another, 50 of another) which might be better for someone who just wants to have a supply on hand at a great price but if you are looking for one fairly short (but not too short) valve stem, that's a good bet. By the way, I understand that there are two different sizes (for the hole in the wheel). Whatever it was, I was lucky that it fitted my Ford wheels perfectly. (If anyone knows what size this is or that it doesn't fit, please share!)
