I don’t have any vibration while running a fully clipped track and can’t really see how this skid can be blamed to cause a vibration. The approach angle is better then the mono and the rest of skid is only touching at the sliders and wheels. Nothing complicated here. I do think this skid tightens the track as it compresses. Having that said, maybe some people had track tension set to tight and slightly warp the drive axles while suspension was stroking? Seeing that many people installed this skid right around the time and mileage range where many others ended up breaking drive axles.
So many things can cause a vibration and I just can’t see how this skid is to blame.

My new drive axle had about 1,000 miles on it when the ZX2 was installed. Again: the day before the skid was installed the monoshock ran 100% smooth. After installing the ZX2, the first ride showed immediate vibration. I guarantee if I throw my mono back in it will not vibrate.

.....I don’t have any vibration while running a fully clipped track.....
If it is the clipping, I would just like it explained to me - the same track does not vibrate on the stock skid - does not make sense - three things I have taken notice to though - the front wheel on the ZX2 is back 4" farther than the Pro - maybe an additional wheel? - second, the width between the idlers is not exactly the same as the Pro possibly causing the wheels to hit the internal lugs? - additional spacers? - and last, the Pro has two sets of wheels at the top of the skid at the upper mounting shafts - the ZX2 only has one - without these the track could be hitting on the bumpers of the front mounting shaft - that would transfer directly to the frame and explain why it so pronounced - I don't know if wheels could be added at that location or not - would probably need to change the axle!! - those are the only causes I can figure out!!!

Fully clipped, 108 studs down the middle, tightened, several times, till no ratchet. No vibration. I will admit, she does wander on the track alignment, but a happy medium seems to work well. Rebound dampening, count me in! I just blame my stock shocks - front, but from riding enduro bikes, it's definitely the rear.

If someone has got some time and snow would you try removing the very front set of wheels that are mounted on the inside of the rails. It is the set that has a shaft running between the two rails.
I was looking for a source of the vibration today and found the spacing between these wheels and the lugs on the track is way too close. Take a look and see if yours is the same.

The very front inside wheels may be the source of the vibration. On the 151 kit you remove these wheels and place them on the extension kit. I have some minor (very minor) vibration but it may be from my new extroverts or the fact that my new track isn't fully clipped. My old predator was closed every third.

The spacing on these wheels is 5" center to center along with the two bigger ones at the inside rear - on the stock Pro they are 4-7/8" center to center - along with this the two sets of lower idlers are a bit tighter than stock - good place to look first then I'm going to look at the bumper on the front mounting shaft!

I have looked this skid over again and again trying to find this annoying vibration. I know the fins look like they could be the cause but I am not sure that they are. My reasoning is, they may appear close but there is enough of a distance that it should not mattter. When I sit on my sled I am not sure it moves at all, maybe a hair but that is it. So the track would still be in the same position when driving. Now those front wheels and maybe even the rear axle wheels are so very close to the cogs on the track that even the slightest shift they would be running over the cogs and cause the vibration we are feeling. Maybe if we still have some snow next week I will head out to the power lines and remove the front set of wheels. The rear ones will be much more of a pain to do. I just hate to touch the skid now that the bolts are staying put.

I guess I am real lucky when I installed mine I just eyeed up the alignment and never touched it again and took random measurements throughout the year and it never moved it was same distance on each side of the tack to the rear wheels. Maybe its a bad wheel somewhere?

I removed the front wheels and tested for a short ride this weekend. I still need to test it more but I do not think these are the issue. Although the wheels have some pretty major damage due to the track clips. The wheels are split from running over the clips. I will post pictures later.
The vibration is strongest all they way up front in the foot wells. My drivers have over 13,000 miles on them and do show some wear. The edges of the teeth on the drivers are worn down. Could the new approach angle of the ZX2 be causing the track to not ride correctly on the drivers or could they be causing the track to skip?
The people that have no vibration how many miles are on your drivers?
The people with vibration, how many miles?
Just a thought, searching for something as the manufacturer refuses to help.
I will be replacing the drivers and drive shaft during the summer and will not be able to test until then.

I had 2,000 miles when ZX2 was installed and always had vibration since installed.
Where is Jeff he always answered every question when selling last summer this thread is two weeks old and not one post on it from him?

My drivers are brand new doo extros and little vibration.

I've gotten close to 4000km on the ZX2 this year and it seems that the vibration is quite prominent lately.
My track seems to be a little on the loose side and my inner idler wheels are getting pretty much chunked up, much like my Proactive suspension did.
I don't know how much tighter I can adjust my track however, as the tensioners are pretty much maxxed out.
The theory on the inner idlers causing the vibrations are interesting though, and I may try removing them, or replacing them to see if this has any effect.
