Arctic cat snowmobile handle Bar riser Blocks?

I am looking to put a handle bar riser block on my 2008 arctic cat f5. I have been told that i can get a 4in block in it? Is that right?|||You can get a 10'' riser you just have to make your lines ( brakes, gas, choke lines) longer then they will fit. the factory gives you some play with the cables most of the time.
