Here’s the same set on Amazon. if you can afford to spend more I would look around at other brands . But having said that 232 4.5 star reviews isn’t bad , do some google research on real world first hand reviews from guys that have ran them .
That's one of the many knock off versions similar to the ams slingshot. I had a set of them on my 700 Kodiak the day I bought it. They would not balance, shook the teeth damn near out of my head.
