Snowmobile question

We do all our riding in Northern Wisconsin and the UP......my fleet of sleds are all from 2004 to current and rack up big miles every year...... The question I have is..... do any of you change out torsion springs when you do shock rebuilds ????

I have had the shocks rebuilt on a few of the sleds, but have never changed out the torsion springs ( don't know if they wear out) we are talking 19,000 miles down to 5,000 across the sleds with original springs, some sleds after shock rebuild seem to still have sag.......

Thanks for your advice.

Thru the years I have changed both shock and torsion springs. Torsion springs more often than shock springs. As to how often I guess it depends on your riding style. Trail rider like me? 5K on the torsion and 7-8K on shock springs. On average that's about 2 years on the torsions and 3 years on the shock springs. In the grand scheme of $$, they're fairly cheap to keep fresh.

Just my .02

It depends on your riding style and how much you care. They do wear out. I always swapped mine out for stiffer ones when I had torsion spring style sleds.

It also obviously depends on the weight of the rider. I have a little bit of unique experience on this matter. I am collecting 2003 ZR 900's. I have 4 of them now. They are 12 seasons old. The two non SnoPro's both sag on the front. Neither of the SnoPros seem to sag at all in the front. There are lard-butt springs on the back of one of the SnoPros. It doesn't sag as much as the other 3. Duh. So I think that it depends on the sled to some degree. Some sleds come with better springs than others. Base models use the cheapest of the cheapest. When I rode Apexes the straight Apexes had terrible shock/spring setups. You had to go with a GT or an Air-shocked RTX. So it translates across brands. When we were young and stupid and rode 1986 Indy triple 600s we bottomed out the front ends all the time hitting field crossings really hard. So, being from farm country we swapped out those front shock springs for John Deere cultivator springs that just so happened to fit just right. Problem solved. Sorry to wander. YES - if you run high mileage older sleds if would probably be a good idea to change springs every 5000 miles. And elevate the sled in the summer to get the weight off the springs.

Shocks don't hold the machine up, they dampen suspension movement. Yes springs do wear out. Depending on rider weight & spring settings, you may be able to adjust the spring block up to the next setting. Also, set them on the lowest setting in the spring, just elevating the sled doesn't remove all the tension (this doesn't either but it helps.)
