MSD Crank Trigger Kit for Small Block Chevy 7" Balancer 8610

Precise ignition timing is the foundation of reliable engine performance, especially in high-RPM racing applications where timing scatter can cost you consistency and power. The MSD 8610 Crank Trigger Kit eliminates timing drift with a flying magnet design that delivers rock-solid signal integrity to your MSD ignition system. If you're running a Small Block Chevy with an aftermarket ignition controller, this is the upgrade that transforms guesswork into certainty.

The four-magnet trigger wheel is CNC-machined from billet aluminum and paired with a stationary, non-magnetic pickup—a proven design that minimizes false triggering and electrical noise. Installation is straightforward: the included two-piece mounting bracket accommodates both standard motor mounts and .25-inch motor plates, so you can dial in the pickup position on either side of your engine. Complete integration with MSD 6, 7, and 8 Series Ignitions means you get plug-and-play compatibility with no additional fabrication required.
