The absolute pinnacle of engineering and technology, it's no wonder Auto Meter can lay claim to more motorsports victories than every other gauge manufacturer combined. The patented air core meter movement, wound in house to exacting standards, can move the needle from 0 - 10,000 rpm in 333 milliseconds. An inaugural inductee to the Hot Rod Speed Parts Hall of Fame, no other tachometer on the market has had anything approaching its impact on professional racing. Built for a lifetime of service under the harshest conditions, this is the no compromise tach for no compromise builds. When you're ready for the best, there isn't another choice.
