TST 510 Tire Pressure Monitoring System With 4 Sensors

Description

The TST 510 system has a 5 year battery, so no more replacing batteries, for a long time! In 5-7 years when the batteries need to be replaced, just send the sensors in to TST and they will replace the battery for a minimal fee. The 4 sensor system is great to cover a dual axle 5th wheel, or a class B RV.
