Hi Guys, looking to swap tracks on my 25 SB Assault. Has a 1.35 Cobra, want to mount up a 2". Anyone have a line on good track prices or looking for a new take off 1.35 Cobra?

Try tracks USA. They may have an exchange program

And often they have takeoffs in stock for less. I've bought a bunch of them from that cheaper that way. Including an emergency one they let me pick up way after hours. Great company

Tracks USA for the win - replaced both my XCR tracks through them.

Also getting mixed answers whether the 2" track off a 24 Boost is same pitch as 1.352 Cobra. Anyone.

2" track uses 19/40 gearing and a different chain than the 1.352 which uses 23/40

plus helix and clutching....

Camso Back Country X2 - 146" 9417C

The precision-engineered Camoplast Track BACK COUNTRY X2 - 146" 9417C is sure to improve performance on your snowmobile.

idk what your end goal is but the 1.75 BCX2 seems to be a well regarded track and you're gaining 1/2" over the Cobra which is in reality a 1.25" lug. pretty sure the 1.75" was available on previous SB's and even some XCR's which might make gearing/clutching more straightforward. SB's with 1.5/1.6 ran 22/41 gearing. if you aren't reaching target peak RPM...

the Internet is an amazing thing... 🙄

I use CB Performance for tracks

if you have the camso number, i can check price through my warehouses. i can sometimes beat bruce at tracksusa but not often

TUsa always has a bunch of brand new take offs for less as well. I just call and then drive up and grab them.

Not to mention, they know what fits everything.

Customer service is great as well. I called them after close and they answered. Had a catastrophic track failure and was leaving for a trip the next morning. They helped me out and let me pick it up well after close. Managed to get there, back, and swap the track to leave the next AM. I will ALWAYS buy from them.

I asked my dealer if they had a track for one of my sleds, he said they don't stock them anymore, just get it from TracksUsa, that's where we get them from.

Made the call on Monday, track was at my house Tuesday.

Tracks USA has always been a great company to work with. They specialize in snowmobile tracks and do a very good job with it. Good enough a lot of dealers will tell you to call them.
