-10% 4-1/2 Inch Speedometer, GPS (0-160 MPH)

Holley’s line of analog-look digital precision gauges is made even more incredible with the addition of the matching Speedometer and Tachometer. This gauge is a full 4 1/2 inches in diameter but a smaller 3 3/8-inch diameter version is available for smaller dashboard layouts. This speedometer is one of the finest GPS-based speedometers on the market today. No wiring to the transmission is required whatsoever, so it is a breeze to install. The included GPS antenna with 15-foot long cable allows the installer to place the antenna in the most convenient location nearly anywhere in or on the vehicle. A hot-start feature means that the GPS is usually displaying speed data within 2-3 seconds of power-up. Once operational, look at these incredible features in addition to MPH:

  • 1/4 Mile Time
  • 0-60 MPH Time
  • Mileage / Trip Odometer
  • Direction
  • Time of Day
