  • Chrome Super Bezel with 2-1/4" outer diameter
  • Silver dial face with fluorescent red pointer for easy reading
  • Flat, clear domed lens for distortion-free viewing
  • Modern white LED through-the-dial lighting provides excellent nighttime visibility

Complete Installation Kit Includes:

  • High-accuracy 1/8" NPT temperature sender
  • 3/8" and 1/2" NPT adapters for flexible installation options
  • Direct plug-in wiring harness for simplified installation
  • Mounting hardware and detailed instructions
