Setting up for two up - Heavy duty torsion springs

[cannondale27]

This is on a cat snopro 137' . Did the same modifications . The kit is for the 146' but you could adjust for your type of rail. You could see the differences on list parts between 146 and 137. The major modification is to extend the groove in the leafs.

Perfect!

Thank you. Still not clear to me whats involved but I ordered the parts. Probably figure it when I see it. Nice guys up at PartsPak if you have ever used them before. $118.30 and a little bit of shipping.

Let us know if you have some issues...

Installed most of this last night. Not sure if I extended the groove enough. I cut it just enough that the spring would mount into the existing hole plus maybe 1/8" or so. Used a drill bit and a file. Took out maybe a 1/2" or a little more. It fits.

It also appears I need to relocate the black plastic activator by drilling another hole into the rail. Not sure where tho.

Any pic?

The pics below show the completed effort so far. I think I need to move the activator somewhere as there is no way its going to stay put where it is.

Is it because you not able to put the leafs down?

Ok to anyone who had done this I have some questions as I am modifying mine right now. On the leafs how much did you slot them I think I am a little over an inch and they will still not lay flat in the down position but I am worried by continuing to slot I am dramatically weakening the leaf strength. Then my next question is did you relocate the activator as if you use the hole in the frame it does not drop over center so when the spring engages it just pushes the activator over and defeats the purpose. and then finally should the leafs be in contact with the torsion spring when in the up position? Mine is still a couple of inches from making contact? If you have done all this does it work well or am I better off doing something else. Thank you for any input.

I never ended up installing mine because of the same issues you’re dealing with. Cut too much out and they’ll just break most likely.
I don’t think it should matter if they aren’t laying flat when not in use. You shouldn’t be bottoming out to hit them anyway.
As far as making contact when in the up position, I don’t think they should. They are just overloads and keep from bottoming. They aren’t really designed to be used in place of stiffer springs.
After looking at what it was gonna take to put them on and weighing the benefits, I felt it was a better option to go to heavier springs. I just cranked my spring up tight and dealt with it. Now my kids are driving their own so I’ve been back to solo the last couple years. If nothing else, get a Fox Float shock so it’s easier to adjust. My brother on his XTX had no issues when I would throw my kid his way because I was bottoming out.

Snowbound98 thanks for the info. My issue it this is for the wife on the back not kids, so the weight will be a little more. I am curious if anyone has actually done this and how it worked. I see the one picture of the artic cat and it looks like he just drilled a hole for the cam over, which I could easily do, I would think just move the cam on the rail in the up position and then mark the hole. Just wondering if I am wasting my time though and should just get heavy springs. If I understand you just increased the stock spring didn't purchase new heavy springs?

Correct. I just cranked mine way up to accommodate my 13 year old son and myself. Together we were probably 370lbs and it got me through the season. And that was on my MTX which has lighter springs to begin with. I would recommend finding heavier spring rather than an overload. Your going to be bottoming out and riding that overload if you only do the overload. I would put on a heavier spring and get it set so the ride is comfortable and if you still bottom out on the bigger bumps, that’s where the overload would come into play. That way it’s not like riding a board on the small stuff just to keep from bottoming on the bigger bumps.
