So factory metal skis are junk, bottoms are worn out by previous owner not changing wear bars. I have a friend that will sell me a good set of MXZ plastic skis. (50 for the pair, I figured cant go wrong).

so......

what parts am i going to need to finish this install and do it correctly.

rubber mounts?

carbides, wear bars?

or will they simply bolt on?

or are they not worth the effort and just get new ones..

What year is the donor MXZ? I suspect they will be the standard 2000 era ski doo flex skis. A good upgrade.

Lots of write ups on this mod and yes, it is easy. Do a search and read up on it.

You'll need...

The rubber ski stops for the flex skis.

4, 1/2 locking collars from the HW store or, stack up some washers to make up for the more narrow spindle you likely have.

snorander has a good thread on this mod and he'll be along shortly I'm sure but you can check out his content and see some pics of how it should go.

Google, ebay, the spacers are not discontinued (part # 506133300) I just had the dealer order me a pair this fall. You should have no problem finding what you need. 2 spacers, the mounting bolts and nuts, locking collars (at you local hardware store) and the ski rubbers.

so the locking collars take up the space between the bracket and the spindle?

the spacers take up the difference in bolt size through the spindle?

am i correct.

and just get 10mm bolts and nuts and thats it.

along with new spring rubber?

i think I can handle this.

Yup you got this! You have to remove the old spacers from your spindles. It's a piece of cake. The hardest part was cutting down the rubbers to fit :)

On those collars...most hardware stores will carry them. If you can't find them, simply stack up washers to fill the gap. This works just as well.

Just in case you're unclear what it looks like. If I remember correctly the correct ones are 1/2" thick.

so I picked up my skis yesterday.

got a set of ski doo plastic skis from a 1999 mxz. in great shape, but the holes through the mounts have a spacer in them.. is this all I need? along with the bushings through the spindle.

Also picked up a set of simmons flexi for the wifes polaris for 100 for the two sets..

I've found these at farm supply stores in our area. Fleet Farm in Fargo will have them...yeah I know the distance :smile_old: Tractor Supply or many implement dealers would have them too I expect.

And those red loops are always good for an extra hp or 6.

so tried to install the skis this weekend and ran into a problem

The spacer #506133300 does not fit the spindle on my 1995 Formula STX. I looked at this two ways. If I remove the factory installed bushing from spindle the hole through the metal is way way to large for the spacer to fit correctly. And there is no way to drive the spacer in the factory installed spacer. So I must have the wrong spacer (checked packaging and found #506133300). So I will need to drill the factory bushing out enough for the new bushings to fit snugly into or what?

what gives? do I need a bushing that holds the bushing into the spindle?

was frustrated because I had a warm day and tore sled apart and didnt get to ride. arrrggghh..

So..... Seems that my skis were a bit different than what everyone runs when they swap the skis. My plastic skis were from a 1998 MXZ. Changed the front grab handles to red no problem. the aluminum saddle part has very large holes in it. there were bushings that kinda press into this hole and also take up space between the spindle and saddle. they are 12mm hole after I realized I didnt need the bushings in the spindle. everything is 12mm i guess so all I needed was some longer 12mm bolts, nuts and washers.

Installed and wow big difference. Had to ride on some hard crusty snow and the turning and handling was way above the factory metal skis.

Strange, all I had to do was take the original bushing off the spindle (2 bushings per spindle) and put the new one in. Fit perfectly on the 2 sleds I did. But glad to see you got it squared away. Yes, they make a huge difference!
