Save space on your dash and provide a clean look with AutoMeter's Electrictronic Tach/Speedo Combo. Taking the highly precise circuits from the individual speedometer and tach and combining them into one unit gives you the accuracy and the response time you need and the convenience of a one piece solution. Compatible with nearly any factory speed sender and 1-12 cylinder applications, this unit is simple to calibrate and designed with the type of durability you expect in an AutoMeter gauge. AutoMeter's GPS Speed Sender is also compatible for an easy, plug and play solution.
