MSD Two Step Module Selectors

4.92 out of 5 stars 24 Customer Reviews

These MSD 2-step module selectors let you choose from two different rpm limits that can be activated at different times. For example, you can use a lower-rpm module for staging and then automatically switch to a higher-rpm module after you release your trans-brake or line lock. They require the use of plug-in modules, which are available separately.
