Don't use these and I mean don't use these if you ever want to fill all your tires. I installed them on my F250 in May 2019. My tires hold air pretty well and the low 3psi doesn't bother me. I decided to fill today as I had a low pressure of 5psi on a normal 60psi fill. I can't take these things off. They are different in metal from the brass valve stems and now I bet on cheap valve covers that cost me over $150 a tire to get new sensors to take them off. My TPMS is built into my valve stems, they are molecularly welded to my valve stems. I gave 5 for durability, they never come off. I also installed them on my trailer which uses Ford trailer TPMS sensors similar to my 250 sensors. So 150 * 8 = $1200 is a good deal for nice cheap valve covers.
