24 Catalyst 600 ZR ATAC 137 - STUDS

[Barfy]

Groomed trails, lakes. Moderately aggressive.

It's been some time since I have had a studded track, 02 ZR 800 CCE, 192 I believe. I don't need to be that aggressive anymore.

What did you put in? I looked at the Woody's site and they are either at 96 or 144 with 6" carbide up front.

Looking to see what people have done.

A good friend recommended I try Fast-Tac studs, and I'm going with this kit for my Catalyst:

96 studs on a 137 and we'll see how it goes - basic, entry level stuff.  I don't know what I'm going to do about carbides up front yet.

Thats a lot cheaper than Woody's.

If you're running stock skis I'd probably only 96 studs on a stock 600.  I've always run Stud boy PowerPoints with great success fwiw.

@Not greg b did his I believe... 144 might be rather aggressive for trail riding.

I have ran 144 studs in a 600 for the last 25 years. Works perfect with a 4/2/4 pattern or a 3 per bar pattern. I am running the 3x3 pattern for 135 studs, 1.450 height on my 129 catalyst. It would work out to 144 on a 137.

too much weight imo...

it’s right where it should be. 90 studs is track failure waiting to happen on any sled 600cc and bigger built in this century. The one thing that has stayed in the 90s is stud quantities. A current 600 makes same or more hp than a 800 twin from the early 2000s. I tried running a 135 in my 2014 800 and it wrecked the track. Put 168 in the new track no issues. That was the only sled I ever under studded.

If it had a 2.52 inch track you could get probably get by with 2 per on a 136.

true... and they should be 2.52 imo

That FastTrac kit with the 96 studs is 100% good for your sled, and that's also a very quality product.

I agree. The only good thing about the 2.86 137 track is you can use all the 121 inch patterns that have worked forever. If you want to go on the light side find the 120 pattern for a 2.52 121 inch track

if I had yours I'd convert it to 2.52 128" as I just prefer more lugs/pins on the ground.

I would put the 136 1.5 inch intense track on it and make it a yooper bomber. It would be like a riot but it would turn

What about a four wheel kit for the skid?

JT or Larson kit are worth the money for 2 reasons. They use really good wheels/bearings and they also use a billet axel and adjusters. The only down fall to them is they are the most expensive but they will last forever. The stock rear axle set up is very cheaply made. JT is running a sale right now on their’s for 300 bucks which is a really good price on it. The Larson kit is kinda hard to get. JT has a website you can order it from. 

[Not greg b]

Here is a link to the Jt. Might have to call him to make sure you get the right parts for the catalyst. I think it is the same as the procross.

I have also attached a picture of the Larson kit. This is what top xc teams run. These 2 companies make the best kits on the market.

Thanks

Been running fasttrac for years with good results.

Just an FYI what I've been using for a while the standard 2 ply studs with single ply backers. The single ply backers are slightly larger in diameter offering a little more support

I was talking to a stud company at haydays years back when the 1 ply/2 ply was a thing. They said the ply did not matter. They said the bigger pitch track (2.86 skidoo was the first to use) needed the bigger stud heads because of how it wrapped around the drivers not because of the thinner track. How true that is I don’t know. I bought their smaller heads and ran it on a 1 ply 2.52 cobra and never had a problem. I did run a lot of them. I was planning on buying the big headed ones but they said it wasn’t necessary. I also don’t think the brand of studs matters any more. I have ran a lot of them over the years and no brand was better than the other.

I still ran the smaller head stud just used the single ply (SP) backers.

The Air Lite XL backers with the built in "boss" type support are excellent ... super durable.  Before I started using the Performance Stud Star backers, I used Fast-Trac for multiple sleds.  My buddy and his wife, who alternate into new sleds every year have been using Fast-Tracs for the better part of 15 years I bet.  It really is a good, quality, product & the owner was always great to speak with when we'd see him at Hay Days.

Since you're such a weight weenie with traction products, somewhat perplexing you prefer 2.52 pitch which is heavier.

Someone tell racers to take those studs out they add weight

Not much talk about balancing the sled. If you're drag racing, sure, throw everything at it. If you're running stock stock skis with the garbage staggered stock wearbars plus a bunch of studs it's gonna be push city. Smaller stud quantities are fine depending on the application. If you're worried about track longevity use a double backer setup and avoid the outside belts.
