I'm setting my rear suspension on my 600xcsp to the mounts that are below the tunnel.Has any one done this and have you had any problems.I have done this before because I'm a heavy guy and loved it I run studs and 8 carbide.i have never had a problem with ski pressure running this way.I did break the front driver when set up this way but talking to a couple of dealers and they both said it's not a problem.I did put it back down.i rebuilt the shocks and readjusted the track because it's a lot loser.I like that the seat in the rear sits higher.Im a trail rider.The drive on some of theses have broke for no reason before.Just looking for anyone that may have had same issue.Im thinking about drilling hole in frount of tunnel just down 1 1/4 to make not as extrem The back going up almost 3.5in seems to much so that's the only way to offset the difference in back and bring the suspension back to normal riding.Any good advice.Ive had my suspension set up right for over 9500 miles but do like having the rear sit up higher without putting a bigger seat or seat spacer in.lowering the frount I still have plenty of room without the track hiting the front of the rails.Cooling has never been a problem with it on higher setting.
