TST 507 Tire Pressure Monitoring System, 2 Flow Thru Sensors for Metal Valve Stems by Truck System Technologies, TPMS for Caravans, Motorhomes and campervans

Quality product.

Same price as everywhere else. Work great. New design.

They work great bought them for the smart car. They programmed into the main unit perfectly. Since we tow now we can watch to make sure all ten tires holding pressure.

I tow an expedition behind my Mountain Aire- they work great! I am within 1# of my digital gage. I didn’t put on security nuts. I remove when I unhook. Then check and air up before we start to tow again. I have a repeater on RV

Worked as expected, as I have master unit and they work for me.

I bought this for my utility trailer as an add-on to the TST 507 system that I use with our 5th wheel. These paired up with my existing receiver without any issue. Even good quality tires that are within their capacity ratings and expected life span can fail, and my TPMS has alerted me twice so far when a tire was starting to come apart at 65 mph. The warnings came in time to get safely off the road before either tire failed completely.

Work fine.

Just back from 1500 mile trip and these worked great on my trailer.i felt much better rolling down the road and able to keep an eye on my tire heat and pressure

Purchased to replace lost sensor. These newer sensors appear to be improved somewhat and work with the 507 receiving unit which is now 5 years old. Would easily recommend.
