Anybody had any experience with these??? Are they more durable than the stock roller???
Any info would be appreciated!!!!!

just put some on my secondary... i'm not sure if they are better till the snow flies...

my bad kirk, im using hitorque rollers, not rock rollers.. i did'nt hear to many good words for those.... check em out www.hitorquerollers.com do you still run the stock secondary??? i'm gonna try this option from ogden valley sports...uses a torsional spring vs. the stock compression spring... hope this helps keep the rpms up in certain snow conditions

Hi-Torque

No, I dumped the stock secondary for a Supreme Tuner at the start of last season. Much better clutch, easier to work on, and a huge reduction in heat goes hand in hand with better performance.

did you go with the 10.7 or 11??

10.7

kirk i have the same secondary but hav'nt tried yet... what color spring and helix angle? i have a green spring and 50degree helix

what weights and primary spring are you running with that helix? And is that piped or anything or are rpms stock? I have 46 starting angle and I was thinking of going more once i pipe it w/ y pipe. Thanks

well hardcore... i have not tried the supreme secondary yet i have a brand new one but did not take the time to put it on and test it.... i heard you need to lower the cam arm weights around 3-4 grams... i have the speedwerx pipe y-pipe combo should run 7500-7600 rpms .....i did buy some 66 gram weights to try out ..... just curious what you cats are using with the supreme secondary.. yellow white primary spring... like i say havent tried it on the snow yet...

How about the low down on how it performed vs the stocker?
Keep flipping over to his site and checking them out.

stock cat yellow and white is what I have in there currently, I have the dalton adjustables for weights and the are awesome!!! they have infanate adjusability.

Suprised to see you have not worked with it yet after spending the $.

Green secondary is what I used; I started with D&D purple which works well also but, its outer diameter is slightly larger than green and therefore it scrubbed the cover a bit more than I like so I settled with green. As far as helix is concerned, its all up to the type of weights and the spring rate being used. 50 is what Mark at supreme recommends but again weights and spring are key to what will work. I had to drop down to the mid 40s finish angle to achieve 7700/7800 rpm needed for my set up. A 330 shift tension spring is what I used and there are a variety of springs with varying engagement tension available with 330 shift out. Weights; I used D&D Big Dogs around 61 to 62 grams with the four weight clutch which I like much better than three. Those weights carry more weight at the tip which has in my experience worked better for top end. Again its all up to how you are running the sled; trail, drag racing, distance, and hook up.

The XS809 belt is great but, it seems to have a long break in period; it will rev higher when new then drop after 150 to 200 miles then settle. It is very grippy and wears great.

For those wondering about performance compared to stock; all I can say here is that before I spend any money on engine mods, I would buy this clutch!!!! Its that good. Overall performance gain is fantastic once dialed. One thing that guys should be aware of as an indicater of how well there clutching is working is heat. If you cannot hold your hand on the clutches because they are to hot then you are slipping the belt and going slow as well as wearing them out faster. The reduction in heat is the first thing you will notice when its dialed in. Getting the heat out of the stock set up is a lot tougher. Why Cat is sticking with that junk driven? Who knows!!!

well kirk after i bought it i had to much fun on the thing and did'nt take the time because of long trips and such.... will take the time this season though...thanks for your info it helps-out with some first hand info:>)

it performs like i had hoped...i weigh 250lb. and my 150lb. buddy used to get me stock to stock by 3 lengths now its the opposite... right off of the launch to 50 or 60 i pull out ahead then he sits 4 sometimes more lengths back and then we ride that distance apart the same speed to like 109 110 mph. Im still dialing it in. I have some more stuff to do, BTW i forgot about the new prim. spring....scratch the cat one... i went and looked i have the 140-330 spring in there. DO NOT use the D&D white spring its rates are way off IMO.

Much appreciated......................how is it if you both roll on it from say 40 or 50mph?

its not as good as the dead stop when the helix is shifting from its steepest point....both helixes finish out similar. it still has more though, length or so
