A Simple Solution for Reading Vehicle Parameters
Holley's analog-style gauges are a simple solution for monitoring engine and drivetrain parameters. A highly accurate pointer is driven by a high-torque internal stepper motor to ensure accurate movement during rigorous street and racing conditions. The design is shallow and space-saving within a dish or pillar gauge pod. Each gauge comes with the applicable sending unit it is designed to read.
