Every Stewart Warner speedometer, tachometer, and gauge features “Face-Forward Design”, which enlarges the dial and pulls it forward, providing more viewable dial space and better viewing angles. Inside, they have rugged air-core movement, sealed bobbin construction, and high-torque gauge motors for stable and fast pointer response. Resin cases resist moisture and abrasion, and computer-modeled light pipes produce optimal light distribution behind the dial and toward the pointer. Customization is easy, with changeable light colors and outer bezels. Stewart Warner is so confident in these gauges!
