Since 1957, AutoMeter has set the standard in performance, accuracy and durability with their legendary Tachometers. The absolute pinnacle of engineering and technology, our classic and digital tachometers have made a bigger impact on professional racing than anyone else. The patented air core meter movement, wound in house to exacting standards, can move the needle from 0 - 8,000 rpm in 333 milliseconds. Built for accurate measurement and a lifetime of service under the harshest conditions, we have the no compromise tachs for no compromise builds. With our playback tachometers, record up to 80 seconds of engine RPM (Revolutions Per Minute) data and playback at slow motion speeds to analyze vehicle and driver performance following a run. Identify key performance data such as burnout, launch RPM, tire spin, gear changes and engine speed through the traps to fine tune your setup and trip the win lights. Purchase your analog or digital tachometer from Autometer for an accurate reading of your engine’s speed. FromUltra-lite toPro-Comp andCobalt toCarbon Fiber, when you're ready for the best, there isn't another choice.
