MSD Extreme Duty 6ALN Ignition Control

Every MSD Ignition is designed for performance use but the Extreme Duty 6ALN is ready to take on nearly any harsh performance environment!
Originally designed with NASCAR in mind, the 6ALN is equipped with the mandatory 6-Pin Weathertight 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. All of the MSD’s primary wiring meets MIL-86A specifications with special tinned conductors for superior crimps. 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.
