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.

    Solid Product
    Color: Space Gray, Memory Storage Capacity: 32 GB, Size: Wi-Fi
    Product is working very well. Only downfall is charging is a bit slow but, that could be related to the charge cord that came with it and not the device itselft.

    Wow, it’s a bargain in acceptable condition. Works perfectly, and cosmetic condition is just fine (minor scratches on back, screen is perfect). Not buying new again.

    It operates just like a brand new Apple iPad
    Color: Silver, Memory Storage Capacity: 32 GB, Size: Wi-Fi
    The item works great. It hasn’t given me any issues. The battery lasts pretty long clean no scratches no bumps only thing the charger didn’t work, but that’s not a big deal. The tablet is extremely loud. The quality is great. The screen quality is also great strong. It’s just like a brand new tablet the touch screen it’s normal. It works just like a brand new tablet. Everything is great on this tablet. Haven’t had no issues and I’ve always bought used tablets and it was worth the Buy worth the money.

    Reliable everyday iPad with smooth performance but limited storage sadly
    Color: Silver, Memory Storage Capacity: 32 GB, Size: Wi-Fi, Color: Silver, Memory Storage Capacity: 32 GB, Size: Wi-Fi
    The Apple 7th Generation iPad has been a very reliable device for everyday use. It runs smoothly when browsing, streaming videos, using social media, and handling basic apps without lag. The 10.2-inch screen is a great size big enough for comfort but still easy to carry around. The display is clear and bright, and the battery life holds up well for daily use. Setup was quick and simple, and it connects easily to Wi-Fi and Bluetooth accessories. The main downside is the 32GB storage. It fills up very fast, especially with apps, updates, and photos, so it works best if you rely on cloud storage or don’t download a lot. Overall, this is a solid and dependable iPad for students, casual users, or anyone who needs a simple IPAD for everyday tasks, Also I’ve had this iPad for about 3 months now… still in great condition Update : I’ll have to remove a star since the iPad dies very fast out of nowhere unfortunately :(
