When it came to designing a new tire pressure monitoring system (TPMS) it was imperative that ARB developed a system that worked both on-and off-road. The Series II TPMS not only suits both driving styles but also works with four-wheel drive vehicles and trailers.

This is an external system that utilizes valve stem caps that monitor the pressure and send that information to the display that is mounted inside the vehicle. Each cap includes a lock nut and special tools to properly install each cap and lock it in place so they can only be removed with the supplied tools.
