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.

    A better topper from a company I trust
    Color: Black, Size: Twin
    I have a memory foam daybed that has seen better days. The top layer has started to shift from regular use, and I wanted something that would help hold it together. The Bedsure Twin Mattress Topper does exactly that and made a huge difference right away. This is a high quality, well constructed mattress pad. It fits securely over an extra thick mattress and stays in place. The corner bands under deep pockets are strong and keep everything aligned without slipping. The measurements are accurate. There are instructions to dry it, then leave it out to expand. There was no weird smell. What you see is exactly what you get, in a good way. The cushioning is even and comfortable, and the fabric feels thick and smooth. It adds structure while still improving comfort. It has a more premium look and function than expected, similar to what you would find in a Five-Star hotel. It feels expensive. I also appreciate that the color is not white. It looks cleaner over time and feels like a more practical choice. I have used several Bedsure products, and the quality has been consistent. I also like that it is a woman founded and owned brand, and they continue to improve their products.

    adds a touch of comfort!
    Color: Black, Size: Queen, Color: Black, Size: Queen
    I ordered this mattress topper for our guest bedroom. It is soft and adds a little plushness to the existing mattress. I ordered the queen size for our queen size mattress. It fit well, without much overlap from the mattress topper. The topper has elastic corner bands as well as the fitted sheet like band around the edge, so the topper should stay in place. The color is black, as shown and if you use light colored sheets, it will likely show through. To combat this, I used a white mattress protector overtop of the pillow topper. You cannot see it through our protector and white sheets. The topper is more like a padded mattress protector than a true topper. It reminds me of a pillow top, it's not foam just filled to add softness to the mattress. I think it's a great addition, it adds a little height and comfort to the mattress. Overall, I think this is a nice upgrade to our guest room. It fits well, and serves its intended purpose. I would recommend to anyone wanting to improve the comfort of their mattress.

    Try it but have lower expectations
    Color: Black, Size: Queen
    Pros: -fairly heavy -fits right -soft enough to dream on -not too expensive Cons: -kinda lumpy feeling and that’s hard to shake -not the classiest wrap/attachment -a little stinky out of the box that can take a while to offgas or whatever It definitely upgrades a futon mattress, even if it doesn’t want to bend easily with it. It’s meant for a stationary mattress.

    Feels Like Sleeping on a Cloud
    Color: Black, Size: Queen
    This mattress topper completely transformed my bed. From the first night, I noticed how much softer and more comfortable my mattress felt. The pillow-top design adds a plush layer of cushioning without making the bed feel overly soft or unsupportive. I was especially impressed by how breathable it is. I tend to get warm while sleeping, but this topper stays comfortable throughout the night and doesn’t trap heat. The moisture-wicking fabric is a nice bonus and helps keep the bed feeling fresh. The deep-pocket design fit my mattress perfectly and stayed securely in place without shifting around. Installation was quick and easy, and the black color gives it a sleek, premium look. After fluffing up, it provided just the right amount of extra comfort and made my mattress feel much more luxurious. For the price, this topper offers excellent value and has greatly improved my sleep quality. I would definitely purchase it again and recommend it to anyone looking to add softness and comfort to their bed.

    Feels Like Sleeping on a Cloud — One of My Favorite Bedsure Products Yet
    Color: Black, Size: King
    I’ve had really good experiences with Bedsure products over time, so whenever I get the chance to try another one I usually do, and this mattress topper definitely did not disappoint. This one went on my mom’s king size bed and the difference was noticeable immediately. The topper has a soft, cloud-like feel while still giving enough support underneath so you don’t just sink straight through it. It added a much more comfortable layer to the mattress and made the bed feel cozy and inviting without being overly heavy or hot. I also appreciated how easy it was to put on. The deep pocket design fit securely over the king mattress without struggling to stretch the corners, and once it was on, it stayed in place well through the night. The material feels breathable and smooth, which is especially nice for warmer nights. My mom commented that she slept really well with it and woke up feeling more comfortable than usual, which honestly says a lot. Overall this feels like a high-quality mattress topper that makes a bed instantly more comfortable. Bedsure continues to be one of those brands I trust for soft bedding and reliable quality.
