Overview
Upgrading to an MSD Flying Magnet Crank Trigger Kit will deliver the precise and reliable signal that a high performance engine requires. This kit gives you the ability to control timing electronically through a Holley EFI ECU (or other standalone engine management system / ignition controller). At the heart of the kit is the 3-wire Hall-Effect Sensor that is easier to set up, less susceptible to EMI/RFI interference/noise, and less likely to have false signals than other methods (Distributors and VR Magnetic Sensors). In addition, they are less prone to mechanical failure since there are no wear parts. With the included high quality timing pointer and the use of a direct bolt-on, degreed balancer (see below list for recommendations), you'll be able to adjust timing in the precise increments required for your engine. Coyote 556-173 We recommend using ATI 918047-MSD but will also work with 918047N and 918047NA LS 8 inch 556-174 Designed to work directly with ATI 917302, 918852, 917264 or 917242 LS 7.28 inch 556-175 Designed to work directly with ATI 917777, 917211 or 917234 LS 6.56 inch 556-176 Designed to work directly with ATI 917776 or 917215

Work well but run small
Size: 1 pair black L
They do seem to run a bit small. I bought them for my bf but snagged them from him because I couldn’t resist! I’m about a W8/12 and they were just a little big but unlike others, I just put them on while sleeping and didn’t walk around with them. If you’re just planning on that, they did a great job at sloughing and moisturizing 😎

Good socks they work.
Size: 2 pairs black L
I normally wear size 13&half to 14 men's, and these fit me ok. They sit just below the ankle. They can get a little tight for me so you should look out for that if you are on the thicker side. But they work as advertised and help moisturize your feet. I recommend wearing them if you're going to just be hanging around home for a bit in one spot as they can be a little slippery to walk in if you go fast. Would not recommend going up and down stairs.

REALLY unsafe to walk around in these
Size: 2 pairs black L
They do what they are expected to do, but should only be used if you are stationary. The gel base makes for very unstable footing if walking around

These work
Size: 2 pairs black L
My husband loves these they help his very dry feet. As others have stated they are extremely difficult to walk in so have to be careful but they do work nicely.
