MSD 7915 Pro Mag Lite Magneto 12 Amp Ford 351W Billet Aluminum

The MSD 7915 Pro Mag Lite Magneto is a race-proven, lightweight magneto engineered for Ford 351W engines competing in sprint cars, drag racing, and other high-performance motorsports applications. MSD took the proven foundation of their original Pro Mag 12 and shed approximately 3 lbs from the design, delivering the same championship-level spark energy in a lighter, more competitive package — the Pro Mag Lite.

Key Features:

• 12-Amp Primary Current — delivers 300 millijoules of spark energy at the gap for complete combustion of race fuels
• 40,000 Volt Secondary Output — powerful, high-energy sparks that last through up to 26° of crankshaft rotation
• 16 Rare Earth Magnets — magnetic pickup design provides rock-steady triggering without the need for recharging
• All-Billet Aluminum Housing — polished finish for superior strength and durability under race conditions
• Built-In Rev Control — supports engine speeds up to 12,000 RPM
• No Points, No Adjustment — precision magnetic pickup replaces mechanical points for consistent, maintenance-free ignition timing
• Compatible with MSD Crank Trigger Systems — integrates with MSD's crank trigger for maximum timing accuracy
• Bronze Gear Included — supplied with bronze drive gear, band clamp, cap, and rotor
• DuPont Rynite Cap and Rotor — injection-molded from high dielectric-strength Rynite material; rotor features a clamp-style retaining bolt assembly
• Racing Use Only — designed exclusively for competition vehicles not registered for street use

The MSD 7915 Pro Mag Lite requires the MSD Electronic Points Box (PN 8106, sold separately) to complete the ignition system. The compact housing profile also sits lower for improved clearance around fuel injection setups, and the band clamp mounting design simplifies installation. For racers who demand maximum spark energy without the extra weight, the Pro Mag Lite is the benchmark magneto for Ford 351W-powered race cars.
