Upgrading to an MSD Flying Magnet Crank 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

Long lasting and safer alternative to sticks
Color: Dogwood & Calming, Size: Medium
These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do.
I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.

Your dog will thank you.
Color: Dogwood & Fresh Breath, Size: Large
My dogs loves to chew on these. They make a small mess but not as bad as other chews. They are food for keeping teeth clean.

Nice chew toy
Color: Dogwood Mushroom, Size: Medium, Color: Dogwood Mushroom, Size: Medium
Super durable and puppy loves it. It was a bit hard for her at first but now at 5 months it’s one of her favorite things to gnaw on! It is heavy for the size but seems to be great quality and has given many hours of chew time with minimal wear.

Puppy loves these sticks!
Color: Dogwood & Calming, Size: Medium
Dogs love these sticks! Must smell and taste like real wood because it keeps my puppy from bringing real sticks in the house from outside. She is a heavy chewer and these sticks keep her occupied. We are on our 2nd set.
