Powder extreme gearing for 151" track

472man · Oct 26, 2010

I just found a cheap track to see if my 97 powder extreme has the power to actually be a low budget mountain machine. Anyway I am just getting back into sledding and need some advice on what to use for gearing. Since this is a super cheap build gears that can use the stock chain would be preferred. I don't like trails so top speed is of no concern I just want enough track speed to be able to climb. Any advice would be greatly appreciated. Also any tips on what rail extensions are best would be appreciated as well. Thanks all, Blair

Did you get that mod done yet? if so where did you get the gears and chain. Looks like you actually aren't to far away from me. I am in Twin Falls Id can't wait for the snow to hit. Thanks, Blair

I put a 151 on my powder special 580 last year.

It has 18 top and 43 bottom gears. It really pulls hard but wont win any flat land speed records.

How fast will it go? I would be happy if it would go 60 or so as long as it climbs well. Since your sled is similiar to mine do you have any info or pics of how you did your long track? Also where did you get your parts. Thanks, Blair

if your still wanting to use your original chain, from the gears you are at now try to keep the same tooth count as you drop and gain like from a 20-40 to a 18-42, some good rail extensions if your goin that way are from wps, or tracksusa
I put a 162 on a 96' t-cat mtncat chassis with an 800 zrt motor, and thats the gearing i went with and pretty happy with it

If possible keep you top gear 20 tooth or more. When you use a small top gear like an 18, the chain has to bend a pretty sharp corner, one it robs power, and two it wears the chain and topsprocket quickly. That vintage of sled we used to gear 20/42, easiest safe low gears for a mtn sled with 8 or 9 tooth drivers.

I started by getting a whole rear skid from a i think it was a 2003 Mt cat. The previous owner has already installed the 9" big wheel kit. All together it fit a 151 inch track. I had a local shop bend me up a aluminum tunnel extension ( basically a box with a missing side. I made a new rear bumper out of electrical conduit. My brother in law is an electrition. I got a new snow flap from the local Arctic Cat shop. Its for an M sled but I just modified it to fit. Most of this was just making it work. I extended the heat exchanger lines and mounted it under the tunnel extension.

No comments about the messy garage.

Hey thanks for all the pictures and info. It is great to be able to see it. Does it perform as well as you had hoped? Also I looked today and I could not find gears that low so if anyone has any good sources for them I would appreciate it. BTW that sure is a nice clean garage you have there

Thanks again, Blair

For gears I ended up getting some from a newer mt cat somewhere around 2004 model year. If I remember right you just need gears the same width . I think most are 11 wide in from 04 back. The newer M sleds are different. I wish I could remember better now.

Correction I am pretty sure it is 13 wide not 11... edited

Thanks a bunch for all the tech and charts and pictures. Looks like I have some work ahead of me as soon as I can get the real job to slow down some. Later, Blair
