Speedmaster PCE680.1002 Chevy SBC 350 7" Aluminum Magnetic Crank Trigger Kit

The Speedmaster PCE680.1002 Magnetic Crank Trigger Kit delivers precise ignition timing for high-performance Chevy small block 350 engines. By triggering ignition directly from the crankshaft rather than through the distributor, this system eliminates timing variations caused by mechanical flex in the timing chain, gears, and camshaft.

Key Features:

• 7-inch aluminum trigger wheel with embedded rare-earth magnets for reliable triggering
• Non-magnetic pickup sensor for consistent signal strength at all RPM ranges
• CNC-machined aluminum mounting brackets with extended adjustment slots for precise timing control
• Reversible bracket design allows installation on either side of the balancer for installation flexibility
• Magnets are press-fit and riveted into the wheel to withstand extreme RPM and vibration
• Multiple spacers included to accommodate various pulley and accessory configurations
• Direct crankshaft position sensing for the most accurate ignition timing possible

This crank trigger system is essential for serious performance builds where consistent, stable ignition timing is critical. The crankshaft's direct relationship to piston position makes it the ideal reference point for ignition triggering, eliminating the mechanical variables present in distributor-based systems. Compatible with most aftermarket ignition systems designed for magnetic crank trigger input.
