For Gen Iii And Iv Ls 6.56-Inch 12-1X Crank Wheel-556-183Upgrading 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

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

As expected. Good for medium chewers but not heavy chewers.

Wish I could give more stars after 8 months 🙌🏼
Size: Large (5" x 3.25" x 9")
I purchased this in June and I've come back in January to leave a review. This was the first toy I bought my dog I had it delivered while she was still in the shelter and it has lasted longer than any other toy. Not only can she not destroy it when she's actively trying but she still loves it she plays with it all the time I don't even need to put treats in it she just enjoys the texture. This toy was such a win. I have wasted so much money since then on other toys that say their indestructible and turn up in pieces. I wish I could give it more stars

Dog loves it! For tough chewers for sure
Size: Medium/Large, Color: Dog Ness Monster - Large, Size: Medium/Large, Color: Dog Ness Monster - Large
Dog absolutely loves it, he’s super rough on all of his toys they usually last about 10 minutes bore they are torn to shreds. It’s lasting through his chewing so I’m happy. It’s also super cute.

Cute toy, dog really likes it. I had my doubts when I pulled it out, and honestly so did she, but the soft part bounces, so that got her going. We've had it for about a week. My dog is ~70 lbs and a moderate chewer, and this monster still gets regular play and is holding up well.
