• Perfect ignition timing once and for all
• Self-contained ignition system features Hall Effect magnetic sensors which are not sensitive to RPM changes or affected by dirt and oil
• Improves overall performance by changing the timing less than three degrees, extends plug life, and eliminates the use of points and condensers
• Can be easily installed
• Used and endorsed by many championship racers
• Made in the U.S.A.
• Operation with the Dyna S ignition system requires the use of an aftermarket 5 ohm coil such as part # DC7-1 or a stock points coil from early Shovelheads. Not recommended for operation with OEM coils.

Street applications require use of a 5-ohm coil.
