Mudder American Flag Valve Stem Cap, Tire Valve Stem Caps, Anti-Theft Hexagon Design fits Cars, Trucks, Bikes, Motorcycles, Bicycles, Dustproof Seal, All-Weather, Lock Tight Fit (8 Pieces)

These replaced an earlier and cheaper set of locking valve caps. They cost a few bucks more, but are clearly better made. I'm in sunny and dry SoCal, so don't know how they perform in salty ice and rainy weather, but so far they look brand new six months later. Once you lock them down with the tiny allen key, they are impossible to remove with a bare hand. I have also noticed they seal very well, and I am not having to add air to my tires as often as with the stock plastic caps.

WARNING! DO NOT BUY!! These seized on our stems. The mechanic and the dealer were unable to remove them without possible damage to the sensors. Estimates for the cost to remove the stems and replace the sensors was to be $500. We were very lucky that repeated applications of pb blaster got them off. Hopefully sensors are not damaged. Both mechanics and a tire store told us to never use metal caps. They almost always seize. NOT worth the risk. The cost to remove and replace stems without sensors was quoted to be $150 + depending on how much time was involved. BEWARE.

They are just cute to add to my truck

They are well done, but didn't work for me. To hard later to put in and reinstalled.

These look great.The only thing I am not liking, ever since putting them on my new 2020 vehicle, the tire pressure light has been staying on or tuns off when I am nearing my destination. And I have checked the tire pressure, and they are all within good range (and match my readings on my Toyota app).The light came on the very next day I drove the vehicle after installing.Has any other buyer had this problem come up with their car?It shouldn’t matter what is on the air port... but it is a big coincidence that it happened immediately after, and all readings are fine.

I don't like how you cant get the bit piece on the way in from not being able to see it. Although when standing up or away you cant really see it in the end. Its just the thought I know. Plus this doesnt screw all the way down. You can still see a little but again its hard to see unless ur looking for it

The valve covers work like any other valve cover. Then you use an allen wrench to tighten the locking screws. Well after about 2 weeks I went to check on them as I was about to purchase new tires and all the locking screws must have vibrated out of place. They were all gone. Valve covers still look good. So much for a locking system.

Corroded the threads on the valves. Do not recommend
