I put on new Simmon's Ski's on my SRX this summer.They come with the standard 4"-120 degree carbide runners.Are these good enough or should I update to the 4"-60 degree or 6"-60 degree carbide runners.I have a new 1" Predator 6-pitch track and am not running with any pics this seaqson.What would work on these dual runner ski's the best?
 

I run Simmon's just the way they came and they work fine for me. Not sure it is a good comparison but I do ride an occasional trail. I was 144x2 and now I am 151x2. I love the way they track on the sugar - no darting. I would think that for the cost of 4 runners to upgrade it would be worth at least trying what you have before you spend the $.
 
I run the 6" with a 121, 144, & 151. Rock solid on the hard stuff with all 3 sleds.
 
Thanks nben,I will stick with what I have for now.It would cost me over $160.00 to put new ones on,I'll wait and see.

And Mtn-Track,good to hear they are great on the hardpacked snow to,thanks.
 
I have the deflectors mounted on the ski's already.Should be interesting to see how they work.How does your sled steer in the corners at a high speed?Like on ice and then on hard packed snow and also loose snow.Some say that these ski's push into the corners and don't bite as good as single runners.That is why I ask about the standard runners that come with these ski's.I know on my lawn they don't grab and I need to take a wide turn,were as my single runner's on the SXR turns great and carves the grass.
 
I really never ride on Ice so I do not know. Hard packed and powder I love the handeling. I got 2,500 miles out of my last set of hyfax and still had 1/16" to go when I changed them. Never have over heated, so I think the fins work very well. Some credit for the good wear has to go to having Anti-ratchet drivers also.
 
I have the 6" I think, but I got them that way from my dealer. on the trails (where I ride, no mtn or off trail to speak of) they handle great and dont dart. I had to readjust my skid and front end though, I needed a LOT less ski pressure after I put them on lol!! good luck!
 
Well once we get the snow and the rivers freeze,I'll see how they grab on the corners which are usually hard packed after a couple of thousand sleds have run the same river.The 6" carbides are for a more aggressive ride,so I still may order them ahead of time.Won't be a waste because eventually will have to replace the carbides after a season or two anyways.The 4" carbides are 120 degrees and the 6" carbides are 60 degrees.The degrees tell me what exactly.60 is a sharper cutting angle I assume..being more aggressive and responsive.
 
I did it!!!!

Well I ordered 6" carbides /60 deg. :). They are definitely more beefer and aggressive looking then the stock 4"/120 deg. ones.The stock ones look pathetic compared to these.They cost a few $$$$,but they should really dig in on the corners and on icey turns.Only the best for me,it is only money...right.
 
Be sure to put your 6" runners on the inside position on skis as they do most of the turning.Most the guys that I ride with who run simmons put whatever on the outside even just a set of hard weld bars and it works great, plus it keeps the cost down!Also put some 1/4 in. shims under the back bottom side of your rubber ski stoppers.I can about gaurantee that your skis are out of balance and will wear the runners much faster in the front, most simmons need this to balance them out.It will also dart less, steer easier and more positively and wear more.These shims make a huge difference, I learned this trick from Scott Bergstrom at bergstrom skegs, he says the only ski that he shims the front is slydog and all others need the rear shim.
 
Really!!!!!!

Are you sure about that with the carbides...6"-60's on the inside and perhaps the original 4"-120's on the outside.I know from the simmon's video that the ski will pivet on the inside runners.And them carbides are expensive,saving anything helps.I shimmed my ski rubbers before I installed them on the back under side already.

Yes, it'll work great and when you need runners next time just buy new inners and take the best two from the old four runners for the outside.You don't really need carbide for the outside that much ,but you already have the 4" might as well use "em.Thats great that your already on the shim for the stoppers, I like the change you get with that.I have saw simmons runners without the shims in the stoppers where the carbides are tottally gone in the front and barely touched in the back, not good!I like to check how the carbide is sitting on a flat surface after sitting them up to make sure the carbides are running level or slightly lifted in the front, the little details sure can make a difference between a ok turning sled and one that works great!
 
So basically if I do that,then am I not getting the full Benefits of the dual carbides runners.So basically running straight,mostly the inside carbides are doing all the work,the outside ones then will touch a bit.
 
Just want to set these ski's up properly.Got the chamber at "0",ski's are aligned parallel to each other,did the 1/4" rear ski rubber mount shim.I have read some guys on here do the opposite with their carbides.They put 6" on the outside, 4" on the inside.I realize as you are turning right,the ski will pivet on the right outside edge of the right ski,and the right inside edge of the left ski.Wouldn't you want the more aggressive carbide on the outside edge of ski so when it is piveting on that edge,the carbides really dig in.I guess it is a no win situation here because you can say the if the 6" is on the inside of the left ski...it is digging in good to.But because you are turning right,seems most of the weight will go to the outside of the ski on the right side,not the inside of the left ski as much.This is my thinking...tell me I am wrong.
 
Dual carbides will make it slightly more aggressive, but when it comes to turning the insides do most all of the work.For normal running on snow you still get the dual runner advantage of better tracking and the way the skis pack and hold snow between the runners in the concave section of the ski.Do whatever you want, some of it will come down to setup and personal preference, just sharing how I've helped some friends with setting up theres.
