High winding combinations need limits well above what a street engine uses, and on a module-based ignition control the limit is whatever module is plugged in. This kit covers the 7,000 rpm range on the odd hundreds, so the limit can be set between the values the even series kits provide.

MSD 87471 7000 Series RPM Module Kit Features:

• Five modules covering 7,100, 7,300, 7,500, 7,700 and 7,900 rpm.
• 200 rpm spacing, offset from the even series kits.
• Plugs into ignition controls that accept rpm limiter modules.
• C.A.R.B. E.O. number D-40-29.
