Auto Meter "Factory Match" Rail Pressure Gauge 4th Gen Ram 10-15 Ram 6.7L Cummins

Monitoring your rail pressure is crucial, especially on performance applications in which a tuner and other power adders have been added to the truck. Many times, programmers increase the rail pressure over stock levels that can cause damage to the injectors. Furthermore, other power adders can actually cause you to drain the rail, which will lead to inadequate performance and damaged injection pumps. This sleek gauge from Auto Meter is designed to match the factory dash of the 2010+ Rams for a factory finished appearance.
