I might be wrong but I don't think they make them for snowmobile anymore, or unless your getting them second hand. A friend of mine has a set on is Nytro, they work realy well.
just have one in my rear skid sweet shock works great.i think racers edge sells the elka shocks now,if i didnt have exits already i would have the elkas.
I have stage 5 elkas on my nitro. Top notch shocks for the nitro. Baker sent them to me 2 years ago. The same time Laird from revelstoke had a pair for his nitro also.
PM Tethair, he sells Baker`s stuff. I got Baker`s number somewhere, in my work phone I think. Somebody from Cowtown should be able to help you out. Lotsa guys using his stuff. If you can`t find it, PM me, I`ll get it.
