This RPM Activated Switch enables you to activate and then deactivate a circuit at adjustable rpm points. This is a great feature for engines using nitrous systems so the nitrous can be turned off just before the high rev limit of the engine. The Switch will provide a ground to activate a circuit and can handle up to 1.5 amps. The rpm levels are easy to adjust with the same plug-in modules used with other MSD rpm controls. It can be used on stock inductive ignitions as well as high performance capacitive discharge controls.

You used to have to send the regular switch into MSD to be modified for use with the LS1 motor. We have taken care of this step so the switch will be ready for installation when you receive it. The modified version is $129.99. You can save $50. if you purchase this along with any NOS or Nitrous Express kit. Just note this offer when you place your order.
