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.

    Great for kids

    Super convenient and easy to use especially with kids! Not sticky and doesn’t leave any residue. A little bit of a white cast.

    Easy peasy!
    Size: 3 Fl Oz (Pack of 1)
    Babybun is a healthier option for sunscreen! We use it for our little and the spray for ourseves. This roll on is so convenient! No breathing in the spray for the kids and less struggle. Just a couple quick swipes, rub it in and good to go! Plus it smells like bananas, the kids think its funny with the monkey logo so it has become a game when getting sun ready, winner winner!

    Easy to apply
    Size: 3 Fl Oz (Pack of 1)
    Easy to apply on my baby. We were on a trip to Punta Cana and were out in the sun a lot and this did a great job protecting his skin.

    Go to sunscreen for toddler
    Size: 3 Fl Oz (Pack of 1)
    We love the sunscreen for our toddler (and ourselves) so much! We've tried so many sunscreens out there and we love this one for our 18-month-old and we use it every day. It's awesome that it's roll on so we can apply it easily to our wiggly son and then simply rub in. Our whole family has a very sensitive skin and the sunscreen is not caused any problems. It's gentle and effective. It does have a white cast but all you have to do is rub it in for about 10 to 15 seconds and then you're good to go! We love that it's water resistant because we can't keep our toddler out of the water. I'm going to buy more for Grandma and Grandpa's house and to have in our diaper bag as well.

    Slightly messy but easy to use and fun for toddlers
    Size: 3 Fl Oz (Pack of 1)
    My 3 year old loves this sun screen! The roller ball makes it easy for him to have a bit of independence when it comes to applying. He can roll it on and then we can rub it in together. My only complaint is it is a bit watery which has caused it to leak a little around the cap and sometimes drip as you put it on. For me though it’s a minor inconvenience if it gets my toddler to put on his sunscreen without too much of a battle
