Overview:

For a long time, racers have known that one of the best things to do to an engine to improve its performance is to stabilize the ignition timing. The MSD Flying Magnet Crank Trigger system does exactly that by using four magnets embedded in an aluminum wheel. Although similar in appearance to other crank triggers, the MSD Flying Magnet design works on a different principle. Most crank triggers have a wheel, with steel studs sticking out, bolted to the harmonic balancer. As the crankshaft turns, the studs pass by a stationary magnetic pick-up, triggering the ignition. This pick-up can be triggered by other bolts, debris or even vibrations which will cause a loss of power or engine damage. The MSD Flying Magnet Crank Trigger uses four magnets secured in the aluminum trigger wheel that pass by a stationary non-magnetic pick-up to trigger the ignition. This "flying magnet" design produces accurate trigger signals and the non-magnetic pick-up cannot be false triggered. Each Flying Magnet Crank Trigger includes a two-piece mounting bracket for the non-magnetic pick-up that in most cases will work on either the passenger side or driver's side of the engine (the SB Chrysler and SB Ford brackets mount on only one side). The CNC-machined aluminum bracket securely holds the pick-up in place and is slotted to provide a wide range of timing adjustment. Spacers are included so you can mount the bracket on engines with standard motor mounts or engines with a .25" motor plate. These systems will trigger MSD 6, 7 and 8 Series Ignitions and all MSD Timing Accessories.

    Nice Phone mount
    Great phone mount—stable, easy to use, and gets the job done! I’ve been using this phone mount for a few weeks now, and it’s exceeded my expectations. It holds my phone securely, even on bumpy roads, and the adjustable arm makes it super easy to get the right angle. Installation was a breeze—took less than 2 minutes. The grip is strong without scratching the phone, and it feels sturdy overall. Highly recommend if you’re looking for a reliable mount!

    Perfect Phone Mount: Secure, Versatile, and Easy to Install!
    This phone mount has truly exceeded my expectations! It’s incredibly easy to install and holds my phone securely in place, providing total peace of mind while driving. What really sets this mount apart is its impressive versatility—I've never seen anything quite like it. The base attaches firmly to the air vent, and the adjustable arm allows me to position my phone precisely where I want it, with the freedom to tilt it up, down, left, or right. Plus, it doesn’t interfere with air flow from the AC, which is a huge bonus. Although my wife's phone case isn't MagSafe-compatible, the included metal ring works seamlessly with it, and my MagSafe case connects just as smoothly. I couldn’t recommend this product more—it’s been an absolute game-changer for us! This is a personal purchase, and I’m thrilled with it. I’ll be sure to update if anything changes.

    Secure and great fit
    I gave this product a chance and it did not disappoint! I did not need to read any instructions for installation and was able to quickly and easily figure it out. Installation takes less than 5 minutes. Just align the mount to the top corner of your tesla screen and turn the dial to adjust the tightness. Once tightness is set, just test to see if it’s really fitted by wiggling it around to check for looseness. I like the fact that I can adjust the angles of the mount easily. My phone can be angles to be on top or side of the Tesla screen. When driving, my phone does not shake one bit. When it’s time to remove my phone, just give it a quick pull to detach and that’s it. The build quality is also very nice and I like the design of it overall. I think it’s a well thought out product. Definitely would recommend to friends and family with Teslas.

    Good mount but…
    This is a solid mount for the Tesla monitor but the mounting points on the corner of screen caused my screen protector to bubble up. I had to return it unfortunately.

    Tesla 😋😉 jeep phone mount.
    Bought this to go in my jeep, perfectly attached to the corner of the screen of the screen, the only down side is since my screen raises and lowers over time with the vibration of the jeep it does make the screen slide down. But the magnet holds the phone very well as long as it is aligned properly to the back of the phone. I know it say tesla mount but my choice of smart stereo for my jeep is not a flush mount, it sticks out and has a cd player in the deck. As well the screen raises and lowers for access to to the cd player. So perfect for my jeep.
