Holley is the legendary American carburetor and fuel-injection brand — over 100 years of induction history. From the iconic 4150 four-barrel to today's Sniper EFI conversions, Holley remains the choice for muscle car restorations, Pro Mod, and gasser builds.
Achieve rock-solid ignition timing with the Holley 12-1X Hall Effect Crank Trigger Kit, engineered specifically for Big Block Chevy engines equipped with an 8-inch balancer. This flying magnet trigger kit is designed to provide the high-resolution signal required for modern EFI systems, ensuring your engine runs at peak efficiency across the entire RPM range. By moving the timing reference directly to the crankshaft, you eliminate the inaccuracies caused by timing chain stretch or distributor gear wear.
This kit is a must-have for high-horsepower BBC builds where precise spark delivery is critical to preventing detonation and maximizing power. The Hall Effect sensor technology is significantly more reliable than traditional magnetic pickups, offering a robust signal even at high engine speeds. Whether you are drag racing or building a high-performance street machine, this kit provides the consistency you need. Experience the difference in ignition stability with high-quality components from GGCRACING.
