This is a new, reproduction 5300 RPM Redline Tachometer Assembly. This unit is electronic. There is a setting that will make the tach operable with LS engines! Great for Retro-Rods, or cars that have no tach drive generator or distributor. Each individual part in this tachometer is new. The tachometer is calibrated properly using a digital square wave generator.
There is a simple 3 wire hookup and the unit will install in your dash cluster without any modifications should you or any other owner desire to change back to the original mechanical unit!
Why waste time and expense on a used part? If it has not been rebuilt already, you can bet it needs it!
