FAST 301285 Magnet Crank Trigger Kit Small Block Chevy 8-Inch Balancer Hall-Effect

The FAST 301285 Magnet Crank Trigger Kit is engineered to eliminate the timing inaccuracies found in traditional inductive crank trigger designs. By replacing the conventional 2-wire inductive pickup with a digital Hall-Effect sensor paired with Samarium Cobalt magnets embedded in the trigger wheel, FAST delivers crankshaft rotation measurements accurate to ¼ of a degree across the full operating range of 0 to 13,000 RPM.

Key Features:

• Digital Hall-Effect Pickup — significantly less susceptible to electromagnetic interference (EMI) than traditional 2-wire inductive designs
• ¼-degree timing accuracy maintained from 0 to 13,000 RPM
• Voltage-independent accuracy — performance is unaffected by electrical system fluctuations between 7V and 30V DC
• Samarium Cobalt magnets installed directly in the trigger wheel for precise, consistent signal generation
• Clean square-wave output — compatible with standalone ignition boxes and major EFI systems including FAST EZ-EFI 2.0, XFI Sportsman, and XFI 2.0
• Integral LED indicator for simplified timing calibration and on-car diagnostics
• Billet aluminum construction — trigger wheel and pickup brackets are CNC-machined and black anodized for corrosion resistance in demanding race environments
• OEM-quality braided wire wrap protects the pickup pigtail from abrasion and heat
• Weatherproof Deutsch connector terminates the wiring harness for a secure, moisture-resistant connection
• Designed for Chevrolet Small Block engines with an 8-inch harmonic balancer
• Plug-and-play compatible with FAST XFI EFI systems
• All required hardware included

The FAST 301285 is designed for serious racing and high-performance EFI applications where consistent ignition timing is critical. Its broad ignition system compatibility, durable billet construction, and advanced Hall-Effect technology make it a direct upgrade over conventional crank trigger setups.
