The difference between pro and khaos length is half an inch. I haven't had any issues doing that with two Khaos sleds now.

It’s not Thomas racing TRS is completely different you can use your factory skid shocks if you like. TRS has longer front arm and moves the rear idler wheels back but is designed for easy removal to go back to stock setup. Thomas racing skid looks exactly like a lynx but I have no experience with that skid have only seen photos.

Here’s TRS setup. Might confuse people because it’s Toby Shepard edition NOT Thomas racing

LOL I have a serious problem buying snowmobile parts yet I constantly ride with people that consistently show me there are no shortcuts or substitute for rider skill/ability the best way to improve what your sled will do is ride more and challenge yourself to improve your skill
It's true. Also, the faster and more aggressively you ride the more you can execute. Ride more, slay more.
I thought 1 may be to much of a point load on the antistab / cross shaft
But should be ok ..
For those interested Iceage has a pre drilled limiter thwt is swtup with the pro rmk position khaos and a maxed out khaos option hole in it.
For guys on the 155 3.25 especially the khaos is honestly obnoxious and gets stuck in wheelies. Even woth additional preload and max stiff dampening on rear track shock it's very easy to completely overpower the skid in deeper snow.
My 24 khaos 155 3.25 I have sucked to the pro position with added rts preload and compression dampening. This is still a wildly playfully sled but is much more usable and less exhausting in tech terrain.
Is a 165 going to be more planted? Sure. I think with some minor adjustments tho a 155 is still the best all around combo and with just a. Few adjustments for firmer snow can be crazy and playful still vs being stuck on a 1 65.

There are definitely benefits to the 155. It's very popular for a reason.
I'm just a 165 guy... but was glad to have the 325 155" for a short trial period.
Full wet weights.
Significant weight difference between 155 and 165
8# difference between them is pretty minimal IMO.
Same as 1.31gal of fuel, or an empty small volume airbag pack.
The actual weight difference between them is minimal but the feel is quite a bit more.
It's interesting you say that.
I mostly notice the downhill "push" on the front end you get from a longer track, especially the 325, while descending or maneuvering around corners at lower speed.
The shorter track does get on edge (static, not moving at all) easier, which is likely because the distance between the points of contact (carbide and back of the track) is shorter. Makes turning around in small areas easier.
Haven't noticed any difference in moving/rolling/loading 155 vs 165 sleds.
Every option has benefits and drawbacks. For our snow, and the zones we ride, long tracks rule.
But there are of course better/younger/stronger guys who can make 155s or even 146s go anywhere. 8lbs isn't the difference maker for them... it's momentum and double tennis-sized balls between their legs.
