Whats the deepest lug for a Fusion

[Wingwalker]

I want to extend the track on my Polaris Fusion 900 121 to either 136 or 144 using tip up extensions I like the idea better of the 144 with tip up rear as i still get the benefit of a short track on the hard stuff but gain the ability to go into some deeper powder
Does anyone know what the longest lug size that will fit I would like to go to a 1.75 backcountry track if thats possible current track is a 1.0 I think

Thanks in advance for any info you guys can give

i curently have a 121 challenger track with a 2" lug on my fusion and have room to spare with no other modifications, asside from dropping a couple teeth on the top end of the chaincase, so you should have no trouble putting 1.75 on yours. i am looking into extending mine to a 144 as well except im trying to figure out if i can make room for a 2.5

I have had two fusions, and the last one I put a 2" on it and loved it!! Thing would stand up on end in deep snow!!
