I used the RSI scratches on my 16 Renegade. I mounted them up against the triangle hole just behind the last wheel. I had to fab a small aluminum plate with two holes drilled in it to span the triangle hole on the backside. Worked great and I didn't have to drill the rails.

This is exactly the kind of info I'm looking for, thank you!

 

I've got a 2016 800 MXZ XRS and put rail scratchers on last year. I find them to work much better than the tunnel Mount scratches I already had. At times I use both. For me it's hands down real scratcher for Effective Cooling and lubrication.

 

What style / brand did you go with?

 

I have the tunnel mounted ones in addition to my ski mounted which I think are far better.

 

I didn't mention I have ski ones also, homemade. They do kick up a whole lot of snow. The rail mounted Ski-Doo scratchers aren't designed for my 129 skid. In the off season, with the shocks out I played around and found a spot that they would still work and not interfere with anything. It was worth it.

 

ski scratchers make the most sense to me atleast they loosen up the snow and ice in front of your track so you can throw it up and get the benefits of it, that said i ended up getting myself a set of tunnel mounted for my 16 gade

 

Here's a pic of the backside to show the plate I fabbed up. Simple really.

On my Phazers I mounted the OTTP brand to the Curve XS skis. These have worked really well so far this season.

And here's another odd combo I came up with. I had bought two of the SPI rail mount kits but found out they won't fit on the 17 Grand Touring due to the wheel placement being different than the Renegade. I bent up some aluminum, drilled and notched it to fit into the Curve skis, then mounted the SPI's to it. Also added a stainless rod for a holder when not in use. All this is held on by one of the wear bar nuts, no holes drilled. Works great!

I bought the skidoo rail scratchers first then I bought SPI off eBay, they are exact and had to have been made by the same company. You can get replacement Springs from SPI for under $40 for both. There are sellers on eBay that sell just individual Springs.

 

I wonder if the RSI rail scratchers are the same as Skidoo? and both are the same as SPI...
What about all the bolts and brackets? Identical?

I always tend to go with the more expensive item, within reason of course...

 

Everything looked exact to me.

 

This was already on my 13 renegade when I bought it in fall 2021. Used it a couple times. Seemed to work fine. The only thing that bugs me is after 1000’s of miles it wears a groove in the top of the rail
