Permanent Valve Stem Replacement Kit | Heavy Duty Metal Emergency Valve Stems for Tubeless Tires | Quick Install from Outside of The Wheel | Made in USA from Quality 360 Brass Components

These things really work! Our aftermarket TPMS system was causing the rubber valve stems to flex and contact the wheel at highway speeds.These seen pricey, but it was much less expensive than having the tires dismounted to install conventional metal valve stems.Installation was very straight forward, easy and fast.

As the title says, these things work. I had an old, crusty valve stem on a tubeless tired used motorcycle I purchased. After about a year, it suddenly developed a catastrophic leak through the cracks in the valve stem, leaving me stranded temporarily. I didn't feel like paying tons of money for a shop to remove the tire and replace the valve stem, and I didn't have the means to remove a tire at home easily, so I figured I would give these things a try after someone recommended them on stromtrooper.com. What do you know? They work great, and they're dead easy to install, even without removing the tire. I tried to remove the old valve stem as best I could with some needle nose pliers and a flathead screwdriver and managed to get most of it out from the outside of the rim. Some pieces did fall inside the tire, but I haven't noticed any negative effects from there being a few small pieces of rubber in the tire. I put this thing in the rim, tightened it down, and voila, solidly sealed tire. This nicely machined replacement valve should probably be the default valve as it works, is easy to install, and is made of metal, not rubber. I pumped the tire up and it has held the same psi for about a month now. Very satisfied. Also, made in the USA.

Works great. Installed on a John Deere bunker drag.

you can’t beat this if you can’t get to the back of the valve for whatever reason. It simply bolts in and effectively does the job. I think it’s about 10 bucks too expensive, but it is a quality product. they are selling as a pair, I would like to see them sell it as a single unit to reduce the price.

I was skeptical about buying a valve stem replacement kit because I was unsure if I could make it work. However, I was tired of inflating my tractor every morning before I started working so I did some research and Colby had the best reviews and the easiest instructions. I did exactly as written and I was done in less than 10 mints and the tractor tire is holding air just fine!

I knew the 25 412 rubber valve stems I bought from Ebay for $5.00 seemed too good to be true. Yep, they started cracking 2 months after install. I run a scooter repair business out of the back of my home. I just installed 3 of these Colby stems in 1 week. Beats the hell out of breaking the bead, replacing the stem and re-setting the beed. You either take the wheel off the bike, or take on the brain damage of trying to do it while still on the bike. I'm keeping these on hand from here on out.

Easy to install. Worked great

I bought a set of these for both my trucks & tractor and have used one for each & they work great.I bought spares after installing them on my tractor & my son's truck.If you've got heavy equipment or just a truck or 4 wheeler get a set for each of them.They come in 2 different sizes, one that fits large tractor tires etc & one's for smaller wheels like mowers, 4 wheelers etcThey'll save you a trip to a tire store.I highly recommend these.
