An entry level 88mm tacho from Stack designed to closely match the Stack ST38 range of speedometers in both size & style. The gauge features an air core movement which offers a significant price advantage compared to its stepper motor driven siblings at the expense of a smidgen of accuracy.
The ST100 tacho can be used with most engine configurations (2-8 cylinder applications) and features white LED through dial backlighting.
The dial face of the unit is 88mm diameter, with an O.D. to the outside of the bezel of 95mm, an 86mm hole is required for fitment.
