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

Its a shame TST doesnt sell these in a two-pack. My boat only has two wheels, so Im paying for two extra sensors that I may never use.

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.

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!

They seem to work well. I would however make sure you use the security nuts that come with it. I didn’t and one of the caps worked itself loose. Lost air immediately in the tire. Once I put the security screws on we ran about 2000 miles with no issues

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

Did just like product said driving down the road noticed the pressure was dropping off slowly told off look for a nail nothing. Folding the truck stop filled up air entire took off down the road again. About three miles down the road the system let me know the air was leaking out faster than normal and alerted me before it got too low on pressure turned around put on the spare should have done that the first time

Great price ..... works and thats what matter, piece of mind

Product was exactly as advertised. And at better price than any I found.

Shipping was fast , install easy, set up was easy with well written directions

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.
