Ok ya i didnt like the pressure they put on the studs either do you recommend circle.or square backers? So are you going to wait to order yours until you get ur side winder so you can see if the taller studs will affect the heat exchanger. Thanks

I've got the set already...but I might be trying/show casing a new traction product (about the same length) which I can't disclose just yet...otherwise, I'm running them!

Id say 6 per row is about max.... on the 137' thats 288...thats a crap load of studs....and not what I would do...Id focus on a top quality item and balanced pattern around the 200+- mark

I bought a new sidewinder Ltx and am also trying to figure out a stud pattern I've always hated studs but know they are a must for this machine I was going to go 2 up the middle for a 96 count but was told it was pointless for this beast was thinking 2 then 4 all the way around which is 144 i believe but do not want any more ! Thoughts?

After a year on the snow is there anything to be worried about with studding the 137incher? What is everyone using for a tunnel protector? I'm assuming cat/ Yamaha have protectors? Is there any special way it needs to be studded up the middle? I thought I remember guys saying it could not be done Last season?

I ran stock tunnel protectors... but since I stud aggressive... if I was doing it now... I'd go with someone's add on protectors...You can stud pretty much wherever with about a 1.50 stud... including the centre 3.5 inches which has that tunnel vent you front...i say about because most studs net different protrusions... but if mac traction is important... like if you plan on adding power and lining them up for fun.... then studding on both sides of the rail and quantity with length are king... too little quantity puts stress and increases chances of failure i.e. strength in numbers... if you are a touring stock power trail rider...i say 3/4 stud per h.p. is a good rule of thumb...but if you are more aggressive and hit it from a dead dig ...1 per h.p. minimum...doubles add strength but can bring vibration depending on install.. there's much more details besides these details... but a good starting point

So SJ you ran all year without adding anything to protect the exchangers other than what was on the sled from the factory? And I am thinking of just doing a Woody's stud of 1.325 inches. I would like to use double backers and stick just to the center but on Woody's website it doesn't show the use of double backers with the cat quiet pad track. Not sure why?I ran stock tunnel protectors... but since I stud aggressive... if I was doing it now...

I use only Woodys products, but Stud boy has a nice pattern(not a fan of their studs)So SJ you ran all year without adding anything to protect the exchangers other than what was on the sled from the factory?

So is 96 up the middle of a 137 ok for a winder?

IMO you need at least 144 studs in the 137" track which is three per window. IMO anything less than that puts too much stress on the studs and track.
I will probably go with 144 Fast-Trac Top Gun II 1.500" down in the middle with the round Air Lite XL Polymer backers. I have had excellent results with these Fast-Trac studs and backers on several sleds over the years.
I used to stud the outside years ago and that is where all of my tear outs occurred. Since then I have only studded in the middle and have had zero tear outs. I am also from the school of thought that studding on the outside makes cornering more difficult. I like to be able to get the back end to break loose in the corners.
