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

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

Easy to add the sensors to your system. I have a 31 Class A RV and two a Jeep. I did not install the range extender. Works great without it!

Adding these tire pressure caps to our tow vehicle gives me much more peace of mind. We drive a 45’ diesel pusher, being able to monitor the tire pressure and temperatures is added security. Have driven about 3,000 miles since installing, no issues so far.

A must if you are also using the TST Tire monitor. Was less expensive ordering additional tire monitors to go along with the TST kit, that comes with 4 monitors , than to order the bulk kit with 8 or 10 tire monitors! Thanks for offering this product at a great price! Arrived as promised and quickly. Would purchase again from this shop.

these keep you in constant touch with your tires. could really save the day if something started going wrong while out on the road

Package arrived as promised. Package not sealed and did not include user manual. 4 Sensors, two tools and one little plastic package with tiny screws, o ring seals.

Bought these to add to a vehicle Im now towing behind my RV. They work as expected. However, be aware that they are longer and in my case stick out beyond the tire sidewall. Also, they use a different battery than the non-flowthru sensors. The battery is a smaller 1632 and I suspect will not last as long the 2032 installed in the non-flowthru sensor.

had a different brand for years. This one out does it by a land fall. not at all sorry went to theTST

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

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.
