I had 2" on my xc 700 and I could have went another 1 1/2" at most.
Now on my xcr 440 I have about 3" of extra brake line. So I could go about 4-5" before I would need to extend brake hose. With the current throttle I could go about 4" max.
Every sled is different. Best thing is to check for yourself. Take off mounting bolts and use a block of wood to check how high you can go. Remember to turn bars both ways to make sure wires or cables dont get pinched.
