So stupid question...and I am running my son to school so no time to go through the whole thread...but can we actually run the CMX belt (as is) on the QD set up instead of the Poo belt? If so, how much is the CMX belt and what is the difference, thanks.
CRAZY MTN XTREME DRIVE SYSTEM FOR THE PRO RMK
- Thread starter CRAZY MOUNTAIN XTREME
- Start date
Thank you for your recognition of our hard work. We built the first ground up builds of complete sleds in 1991 and the first CMX belt drive in 1999. The CMXDS for the PRO RMK is a huge upgrade over a chain case and the qd. We did not want to make any compromises in quality, so our system was not designed to use any stock parts. Our belt will not fit the stock qd system.
Nice!!!
Nicely done. i remember the early days of your belt drives. We all wanted one. The first one I have owned is the one on my new Pro. To date I have almost 1000km on it and no issues, however I ride with a couple others who have blown belts. It would bring piece of mind to have a system more like the one you have designed.
I believe belt tension should be a good reason for efficiency but I was noticing the actual diameter of the sheaves which appear larger. This would also be a factor in efficiency would it not? We have run extrovert drivers and changed out to big wheel kits for years to run looser and more efficient track systems... same kind of thing???
I believe another selling feature would be the ease of changing belts. The Pro QD is not the easiest change, especially on the hill in the snow.
My final kudo's is the brake system. I was dissapointed when the Pro came out with the brake on the jackshaft. This is even more important with the number of belt failures that seem to be popping up. I really don't want to lose my sled at the top when brakes may save it (may is the keyword but may is better than won't).
I guess the next would be pricing and availability. I'll visit your site and PM you.

Ok i just have to ask. And not pounding the product. I (my wifes sled, but i do ride it hard when shes not looking) have a 13 pro. No issues as of yet with the QD. Just wondering how to justify the double the price for the cmx over the C3 belt drive?? Yea the shaft,yada yada. It appears to be of great quality. All the fasterer hardware is 70?? aluminum or titanim?? what would i save for weight with yours (CMX) versus the C3? I'll be quite frank and tell you im not the guy that will just dump a load on a great advertisement, i need all the info up front, not after the fact before i decide to spend. In all honesty i have never seen the cmx ( looks heavy)system first hand but in the u tube vid it looks very top notch. The C3 also lacks nothing in the quality department and reviews are also top notch. so the big question is why yours over the C3, help me decide?

Very good questions. Thanks for asking. c3 builds a very nice kit for the cost. Problems that are not addressed with just a simple sprocket and belt kit are: The brake remains on the top shaft which when applied puts a severe reverse torque load on the teeth of the belt. I believe this is part of the teeth stripping problem on the qd system. It also transfers a lot of heat into the shaft and the bearing on that end of the shaft which will cause premature failure. The brake on the CMXDS is on the bottom, so the belt doesn't see the effect of the brake. The only reverse torque load our belt sees is engine braking when going down hill. The CMXDS also relocates the driveshaft down an inch and back an inch from stock location, which give you a better attack angle which helps your sled get up on the snow better. It also will allow you to run a 3" track with full sized drivers. Huge advantage over the baby 7 tooth drivers. There are several other advantages to the CMXDS, but I don't want to make this too long. We started the CMXDS in 1999 and did not want to make any compromises by designing it around any stock parts. That is still true today. The cost of the CMXDS is a bargain for what all you are getting in the kit, and if you can afford it you will be very satisfied. Thanks,
By "full sized drivers" what are you considering full sized? 8 Tooth? 9 Tooth? With your 1" down and 1" back can you run a 9 Tooth, 3" Pitch, Driver and a 3" lug track with tunnel clearance?
ok thats all makes sense. still not sure im down with the $ with all due respect. Pretty sure im adding a 14 pro to the tralier, and due to the QD being a less than acceptable will do a change over to both the 13 and 14, just need to weigh my options which brings me to the question not answered. The C3 claims 4 lb loss over stock (chain and gear). What exactly will i lose with your kit, and how far have you taken things on the bolts, washers ect, are they aircraft 7075 or titanium? I really like the fact of brakes in case of a belt failure. What would one exspect it to take to install in labor, and how involved tool wise is this kit? thanks you for taking the time

i was always understanding you could run a 3'' track no problem with it in the stock form??
I consider 8 Tooth full sized for 2.86" or 3" pitch. We run 9 Tooth 2.86" pitch drivers with a 2 1/2" Peak track on the CMX-X sleds we build. 9 Tooth on a 3" pitch would be pushing it.
The C3 kit is also available with an Avid Extendend Chaincase which will give you PLENTY of room for 8T 3.0"p drivers and a 3" lug. Cost is $1660.00 Yes you still have the brake on the jackshaft which is more than likely a dealbreaker for some should they lose a belt at the top of a chute. In my case that 800+ difference in price pays for four years of sled insurance or a lot of belts....
Kind of where im at with it. Again not bashing the cmx just trying to put it all into perspective where i can understand it all, but its not that cut and dried without having all the info. This was my skipped over post.

I think you need to look at what all you get with the CMX drive system. I am impressed with it 100%, no problems with 260 hp all day long. Everyone else has been trying to copy there design for awile now and they all come up short. Great product, kudos to CMX.

I totally see what you get with the system, my only issue is with who ever is doing the replies for the company. I have said it before and again now, it looks very nice, but im not in favor of the way they have skirted my questions and only answered the ones they wanted. That just seems to show deception in my book. Im not asking for the blue prints for gods sake. I mean is it just me or does anybody else see it? I was going to call them today, but i think as i was on the fence anyway, at this point i think i know which way im going to land. Jett it sounds like you have one and like it, maybe you can answer my questions? I have them posted twice now. The one other question i had was this.. Is rotating weight 7 to one, and how much of that belt drive would be concidered rotating, just the brake rotor?
Pick up the phone and call CMX. Ask all the questions you want. Mark will be glad to tell you about his product. He won't bash other drives, he won't give you a long winded sales pitch, in fact he complimented C3 in this thread. No BS and then I can tune into this thread and not read about 3-4 lbs of weight loss when losing stock gears compared to the 20 lbs of snow on your running boards and 7-1 rotating whatever.
LOl, it is alot more fun to spend someone elses cash for sure. Well im probably about out of reach for even reading or replying to this thread as im not a premium member. All i wanted was the respect of him answering my questions just like he did with the rest of the guys on here. Seems like as soon as i asked some that would jeperdize his product he avoided me and i suspect the questions will never be answered at least by cmx. Sure i could call and post what was talked about, but isnt this fourum all about getting "first hand information" for all to see and not third party he said she said. He diddnt answer the first set, then skipped right over them the second time.At this point i think i got his number.
C3 SyncroDrive 2013 kit has been working good on turbo and non turbo applications. Here are some of the benefits of the C3 kit.
275 Grams (0.61 lb) less rotating mass
Currently available in Gear Ratios from 1.77 to 2.52
No break in period
Available with a belt that will handle 60 degree F higher temperature so will work with most turbo kits
More clearance for the bottom gear
Direct bolt on takes as little as 1/2 hour to install on stock sleds (turbo kits may need modifications)
Gear and belt changes in minutes
Inexpensive 8mm pitch belts
(somewhere in that other thread they said, dont quote me but either 4 or 6 lbs less on the total weight)
