Is there gonna be a set up like this for the ascender, drop rolled case ?

How are these going to hold up to abuse?

its the stock shaft out of the new 2018 Cats. But we put our drivers on it and true them, and have a lower price so the 2012-2017 guys get a great deal on the upgrade with all of the parts needed to do it.

Track-shaft???

Thanks; It seems intuitive that 3 lbs less rotating mass would make a difference, BUT I would like to hear from some sledders with first hand experience on the Suzuki Pro-Climbs changed out to the lighter track-shaft before shelling out $250 and my labor.:light:

And then if you add our new lighter brake rotor, it's 1.15 lbs lighter than cats vented rotor, or 2.5 lbs lighter than their standard brake rotor, so you can drop a lot of weight between the two. The rotor is only $109.95

I looked at this trackshaft at hay days and it has an extruded "X" through the entire length of the shaft. It looks very sturdy. I do not see that you will bend them. Maybe SSI could post up a picture for us of the internal bracing

Please do tell us more

I also would like to know the durability! Would it hold up to a boosted sled?

Well, my glued and clamped shafts have never failed for me but this Cat shaft has soft aluminum splines and that makes me nervous. The Polaris shaft has steel inserts on both ends.

Pick your poison, time will tell.

That is a good point as I was only thinking of bending the shaft not wearing the spines off of the end of it. The belt drive manufacturers all use aluminum pulleys so you're essentially relying on aluminum splines with those???

AC tried coming out with a light weight drive shaft in 2014 when the chassis lost 17 lbs, was supposed to be 18 but sent it back to the shelf for durability reasons after long term testing

Guys, it's a cat shaft that they tested and it comes on a factory sled for 2018.
We just put our drivers on it to reduce the price to you guys as a kit.

One thing about Arctic Cat's gears is the spline for the sprocket is quite large.
We have been using aluminum hubs on belt drives now for a couple years and they hold up just great.
Including several drag race sleds with over 600hp.

There is plenty of strength on the splines of both the shaft and the gears, especially with that many teeth.

Actually the Hex outer shape of the shaft with the X on the inside of the extrusion makes the shaft very strong.
