This was my plan with my matryx assault , 2” track and put 39” front end then the sled would be a great 60/40trail. I say 60/40 because I find the assault has many other things that need to be changed to make it a true 50/50. I ended up ordering a khaos 146 and I’ll add a set of small idler and snow flap. Then I’ll be happy. I’m gojng to do a post later about the assault , more of a review and then I’ll shut up.Buying an Assault and narrowing it up would be the best, you gain alot better suspension and snow flap. Who really needs a cut tunnel in areas that dont get snow like out west does? The 2017 SBA I had with Zbroz 39 front end was very complete.
