But since you are in the states, can get them from Fett Bros or Chris at C-TPower.
GW's seem to have nice lookin ones although ive never tested em' myself.
Super good roller change vidya
Hi-torque are definitely the way to go, we have them installed on all 3 of our renegades
 
Unfortunately, rollers are a bit like belt life. Some get much longer life than others depending on riding style. However, I would say that you should at least get 5000 miles and 10000 would be on borrowed time.

The rollers are very cheap and when one breaks it ruins a good ride. So with that in mind, it’s worthwhile to switch to Hi-torque or similar - just not OEM’s.

As for tools, yes you’ll need a few but Chris sells them and they are worthwhile to have. Not crazy expensive and they should be good for many years. When I purchase tools I always feel they are a wise purchase as if I had to get someone to do the work it would cost substantially more.
 
anytime the helix slams into the rollers, there's the potential to shatter them and that's a frequent occurrence when riding. buddy's sled went down due to this at only 400 or so miles on it and ended the day. doesn't take cumulative wear or age for the rollers to crack.
 
We haven´t installed Hitorque rollers for couple of years now. Too many problems, quality isnt where it used to be. These ones lasted for 700km on a summit expert.


What comes to GBoost Extreme Rhino rollers, not a single set has come back yet.

2023 850TurboR is gonna have new stronger rollers, interesting to see how those are like

You must have received a bad set or something. We have sold hundreds and hundreds of sets for the last ten years and never had an issue or complaint. If these were not a quality and dependable replacement part we would not be selling them.
Not trying to knock the G boost at all but they haven't been on the market very long.
 
Yeah we used to install a lot hitorque rollers and for a long time and it was my recommendation too. Problems begun back in 2019 and for two seasons I would say at least 50% were broken way too early, especially with sleds that had clutchkit with aggressive setup and higher angle helix. Also the large distributor here saw the issue as lots of complaints flooded. And I believe lot of people dont bother to even complain, they just buy new ones from another brand or change back to stock ones. My first thought was also that it must be a bad patch of products, but afterall all shipments 2019-2020 were the same. We even contacted the manufacturer straight but they claimed nothing had changed, even though you could see the color difference between 2018 and 2019 rollers. I really hope they have got their product back to quality it was but in my opinion there are better options nowdays.
 
@Driver#96,
thanks for posting that vid which i'd seen before but missed the part about new factory rollers.
in the pic you showed, is that what hi torque rollers look like after they've been used? the larger pieces look metallic as opposed to what looks almost like phenolic material when they are new.
 
At least 50%?? Haha! What a crock! LMAO! Complete BS.
I'd be willing to bet that at least 25% of the members here on this forum run Hi Torque. If there were many failures you would see it right here in this thread.
Feel free to promote your favorite roller to help increase your sales but no need to bash the others.
 
Personally I dont sell anything, but do a lot clutching, testing, r&d. Promoting here does not even do anything in our market, as in Dootalk 99% of users are north americans.

One thing to consider that here in Europe we ride quite low elevations. That means we are able to use steeper angle helixes and harder secondary springs even on deep snow conditions. That equals more pressure and stress for the rollers. I have visited BC twice, and can say that conditions, clutching and problems with machines are quite different than we have here.

I bet rollers are more of an issue here than other side of the sea. And the same goes with belts, 2018 was catastrophical. But companies only look numbers, something that is major issue here can seem as minor inconvience on corporate numbers. After all its a numbers game.

Lets hope these new rollers are strong and in the future no need to replace them with aftermarket ones. Im a bit surprised that doo didnt promote them at all.

Yes those rollers in the picture are from my ex 2020 expert and lasted around 700km. Hitorque rollers are some kind of fibre material an they tend to "compress" in use as you can see. All hitorque rollers looke like that after some riding.
 
Roller longevity depends a good bit on how you ride and how easy you are on the reverse to forward/vice versa transition, that smacking noise heard most times is the rollers hitting the opposing helix face. I replace mine seasonally (average around 3k miles a season) just to be extra safe and not ruin a ride. The Gboost Rhino Rollers are awesome pieces, the Extreme version's even better.
What are the Extreme versions?
 
It's not a matter of if they'll break, but when. I swapped my sled, my old sled, and all of my friend's sleds to Hi-Torque rollers. They're the original, their customer service is truly exceptional, and I agree with Chris @ C&T (who knows just a little bit about clutches ;) ) that they're so ubiquitos that if there was an issue, we'd all know about it.

It's only very recently that other companies have started coming out with competing products, and they may well also be very good. But I stick with Hi Torque because they were the original, are by far the most proven, and have really, really, really good customer service. All "wins" in my book.
 
Was changing mine to hi- torques . Glad I did as one of the originals was cracked right threw. Sled has 2800 miles.

I have a set of high torque rollers on my 2015 600 Adrenaline with no issues and had one set on my 2006 REV 600SDI.
The fiber rollers in my REV shattered. Ruined my S8R4 helix, I just found another used helix since they don't make them anymore and still have to install them as my sled sits in the woods up north aby my brother's cabin in an enclosed trailer. Wasn't happy when the roller took out the helix. I found another secondary and ran that last time I took that sled out.
So, the fiber rollers do go bad. I am sure they are better than stock, but no idea if the Extreme Rhino rollers are better or worse?

Need to find out what the polymer material is of stock and then the Extreme Rhino. Being a Plastics Engineer, I may be able to get the specs on the plastic, but no idea which resin they use to make them and probably won't be able to find out.

You sure got lucky. You were down to seconds before a rough ending of a fun day. I had 7500kms on hi torque rollers on my 1200 when changed out. They look ok to me but want to replace around that mileage or 2 seasons of riding. Bolt broke backing it out but was lucky enough to use a screw driver to back out the little bit stuck in the clutch.

Sounds like you BOTH got lucky! :O

Yeah, I'll probably swap in a new set of Hi Torque every ~10k km. Cheap and easy piece of mind.

I just got a set of the Extreme Rhino rollers in the mail today. Judging by the color of them, and the mechanical properties GBoost states on their web site, I think they are made out of PEEK.
