What kind of suspension is this?

[redneckj]

I believe this suspension is from a polaris snowmobile. I dont know what year make and model that it would have been from though. If you know please post. Thank you!!

that would be an Xtra-10 polaris skid from a 97-01 rmk looks to be a 136 but could be 144.

Thanks for the quick reply. The reason that I am asking is that the left torsion spring is bent and both torsion springs are lazy. I would like to replace them with stiffer springs than the stock springs that are used now. Do you have any recommendations on which springs to use ? It is a 136 track.

2000 and 2001 RMKs had the Xtra-lite suspension. The limiter straps are what stands out to me. I have the parts list for a 1999 600 and 700 and the suspension matches that. So it is definitely an Xtra-10 suspension.

What year sled is it currently on? Who did the Drop and Roll on it?

You can have any Polaris dealer order the springs.

1999 stock 600 and 700 numbers are 7041629-067 7041630-067
1999 700 shows the following:

7041629-067 Spring, Rear, LH, Standard (.359/77 Degree)
7041630-067 Spring, Rear, RH, Standard (.359/77 Degree)
7041631-067 Spring, Rear, LH, Optional (.375/77 Degree)
7041632-067 Spring, Rear, RH, Optional (.375/77 Degree)

I believe that may also have a .405 extra heavy duty spring, but I don't have the numbers for it. These numbers will definitely get you in the ball park and hopefully you get a smart part guy that can find the other numbers.
