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.

    Glow in the dark dog ball
    If u shine a bright light on these balls they glow for 15 min. My dog has a double coat and I live in fl so I play outside at night and this glow ball fits the bill. Lots of fun. The ball is made well and so far has survived the jaws of my king shepherd. Im happy with my purchase and have also purchased them for family and friends

    Glowing Orbs can be fun.
    My dog loves these balls. He can’t break them, which is hilarious. The fact that they glow and double as a cognitive toy when you hide treats inside is a huge bonus. My dog is literally darker than the night. We leave the ball near a lamp for 10–15 minutes, then take it outside and throw it. Watching a pitch-black blur sprint at full speed and suddenly seeing a glowing orb bouncing through the night is unreal. Great toy. Highly recommend.

    The ideal fetch ball
    Our dog is obsessed with these. They bounce well, they’re squishy enough to meet his chewing needs but strong enough to not get destroyed. We do replace them every 8-10 months because after 2-3 20 min fetch sessions almost everyday they do rip. They have a nice weight to them so they’re easy to hurl 20-30 yards.

    The best for fetching enthusiasts
    We have two lab mix dogs that love to play fetch but also have very strong jaws and sharp teeth. Tennis balls last about 10 seconds. I have used these for several years now and they are the best. They glow in the dark for night fetching, have two holes and are hollow so they whistle when you throw them. The dogs chew them like gum when not fetching and they hold up. They last about a year before starting to tear (this is with almost daily use). These balls are their favorites and get they upset if I use something else.
