MSD 8611 Flying Magnet Crank Trigger Replacement Wheel - SBC 7 in. Red

The MSD 8611 is a direct replacement 7-inch Flying Magnet crank trigger wheel designed for Small Block Chevy applications. Built to replace the wheel from MSD's Flying Magnet Crank Trigger Kit (p/n 8610), this component restores accurate crankshaft-based ignition triggering without the need to purchase an entire new kit. A centering ring is included for proper installation.

Unlike conventional crank trigger systems that rely on steel studs passing by a magnetic pick-up — a design susceptible to false triggering from nearby bolts, debris, or engine vibration — the MSD Flying Magnet system embeds four powerful magnets directly into a billet aluminum trigger wheel. These magnets pass by a stationary non-magnetic pick-up, producing consistent, noise-free trigger signals and eliminating the risk of false firing events that can cause power loss or engine damage.

Key Features:

• Replacement 7-inch crank trigger wheel for MSD Flying Magnet Crank Trigger Kit (p/n 8610)
• Four magnets embedded in a 3/8 in. thick billet aluminum trigger wheel
• Non-magnetic pick-up design prevents false triggering from bolts, debris, or vibration
• Red anodized finish for corrosion resistance and easy identification
• Centering ring included for accurate wheel positioning
• Racing use only — not legal for use on emissions-controlled vehicles

The MSD 8611 is the ideal solution for racers running the SBC Flying Magnet Crank Trigger system who need a precision replacement wheel to maintain stable, accurate ignition timing at the crankshaft.
