13.5 in track swap

[skidoober800ptho]

does anyone have any experience with a 13.5 track on their apex, i have one laying around and would like to see how the apex rides with a 128x13.5 under it, i know with the arctic cat f series that one would need an off set bearing kit, is this so with the apex, or is it a direct swap, no modifications required?

i have this track in my sled with a tracks usa rail extension,i did move the upper wheels inward by moving washers around and same with rear axle,also welded extensions on the little metal loops on the top front skid to keep track from getting squeezed between them,i circled them in red on the pic,ive run it 2 years with no issues,the front 2 idlers run kinda close to the edge but no issues
