MSD 3-Stage Retard Control

Product images may differ from actual product appearance.

The 3-Stage Retard Control allows you to retard your ignition timing in three different stages. You can activate one retard for a nitrous stage and another at top end in high gear for more mph and still have another module left over for dual stage nitrous systems. When activated together, the retard amounts are cumulative so you get the total of the three. For example. if you pull 2°, then 4° on the second stage and another 2° at top end, the total retard is 8°. In addition to the individual retard stages, the Three Stage Retard Control has an optional start retard function that retards the timing 20° while cranking the engine. This makes staring high compression engines with locked-out timing, such as crank trigger systems, much easier. Connects easily to your MSD Ignition and can be triggered from points, electronic ignitions, crank triggers or magnetic pickup distributors. Supplied with a 2°, 3° and 4° module and must be used with and MSD 6, 7, 8 or 10 Series Ignition.
