6ALN Circle Track Extreme Duty High Vibration Capacitive Multiple Spark Discharge Ignition


Circle Track Racing ignition designed for stock cars, late models, modifieds, road racing, desert, and off-road racing applications.

The new 6ALN Ignition was designed with circle track racing in mind and approved for use by NASCAR. It features MSD's race winning Capacitive Discharge Ignition design and are combined with heavy duty vibration protection. The 6-pin Weathertight connector conforms with NASCAR's rule 20-6.1 and the cast aluminum housing provides a solid mounting foundation for the circuit board and transformer. For added protection, a two part silicone elastomer encases the circuit board making it impossible for parts to vibrate loose. A special clear base plate is also installed for easy tech inspection.  It also includes sturdy vibration mounts. The 6ALN features a built-in Soft Touch Rev Control which, at your selected rpm, the soft touch begins dropping the spark to some of the cylinders, and on the next cycle, these same cylinders are fired to prevent loading up with fuel. The result is a smooth and accurate limiting action without backfires or roughness. They'll work with virtually any 4, 6(even-fire only), or 8-cylinder vehicle with a distributor, as long as it has a 12-18 volt electrical system. It includes modules for 3,000, 6,000, 7,000, and 8,000 rpm.
