Description:

For a long time, racers have known that one of the best things to do to an engineto 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 othercrank triggers, the MSD FlyingMagnet 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 andis 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 .250"motor plate. These systems will trigger MSD 6, 7 and 8 Series Ignitions and all MSD Timing Accessories.

Features:

  • 6.25" Diameter
  • Absolutely the most accurate way to trigger the ignition.
  • The non-magnetic pickup cannot be false triggered.
  • Powerful magnets are embedded in a billet aluminium trigger wheel.
  • Kits feature special brackets and mounting hardware for a variety of engines.

Quality and durable socks
Size: Large, Color: White (6-pairs), Number of Items: 6
Great quality socks. This pack was a lot taller on the cuff and bigger than previous batches I have had. Not sure what the change was, but giving it 4 instead of 5 because I preferred the smaller shorter ones they previously made. But these are great quality socks, and last a long time.

A Game-Changer for Comfort
Size: Medium, Color: Black, Number of Items: 6
I recently upgraded my workout gear with the Under Armour Training Cotton Quarter Socks, and I must say, these socks have revolutionized my exercise experience. Comfortable, durable, and stylish, they truly stand out in the crowded world of athletic socks. First and foremost, the comfort level of these socks is unparalleled. The blend of cotton and synthetic materials provides a soft and plush feel against my feet, making every step a pleasure. The quarter length strikes the perfect balance, offering ample coverage without being too restrictive or too short. It's like walking on clouds, even during the most intense workouts. One of the standout features is the moisture-wicking technology. I've worn these socks during high-intensity cardio sessions, and they have consistently kept my feet dry and comfortable. The breathability is remarkable, preventing that uncomfortable feeling of sweaty feet that often accompanies strenuous workouts. No more distractions – just focus on pushing through your fitness routine. Durability is another strong suit of these socks. After numerous washes, they maintain their shape and elasticity, showing no signs of wear and tear. The reinforced heel and toe areas provide extra support, ensuring longevity and preventing the dreaded sock holes that often plague other brands. The sleek design of the Under Armour Training Cotton Quarter Socks adds a touch of style to my workout attire. The subtle logo and choice of colors make them versatile enough to pair with any athletic shoes. Whether you're hitting the gym, going for a run, or simply running errands, these socks seamlessly blend fashion with function. In terms of sizing, I found that they fit true to size. The elastic band around the arch provides a snug yet comfortable fit, ensuring that the socks stay in place throughout any activity. While the price point may be slightly higher than some other options on the market, the quality and performance of the Under Armour Training Cotton Quarter Socks more than justify the investment. When it comes to comfort, durability, and style, these socks have become an indispensable part of my workout wardrobe.

Socks work really good. I have very rough and dry feet that tear up my bed sheets. They hold up to my destructive feet. They are soft and comfy!
