MSD 6ALN IGNITION CONTROL BOX - MSD-6430

Originally designed with NASCAR in mind, the 6ALN is equipped with the mandatory 6-Pin weather tight connector to meet NASCAR’s ignition wiring rule, 20-6.1. This special connector provides a tight, positive locking connection with individual seals to keep dirt and moisture away from each connection. Inside the strong cast aluminum housing, the multiple sparking CD circuits are encased in a clear two part silicone elastomer for the ultimate in vibration protection. A special clear base plate is also installed for easy tech inspection. The 6ALN has a built-in Rev Control. These rev controls are adjustable with plug-in modules and will save your engine from over-rev damage caused by missed shifts or driveline failure.
