The differences between these two have been discussed before, but not much on the gear difference, guys that have ridden both(I haven't) have stated they can feel the difference, but what is it????? Sooooo in an ocd moment I got onto Partzilla & Checked them both out, I used my 2017 Grizzly 700 as a base & a 2017 Kodiak, I checked parts that could influence a ratio change, Primary, Secondary Sheave's, Weights, Spring, Front & Rear Diff, Pinion Gears, Ring Gears & High, Low & Middle Gears(couldn't think of anything else) & the result! The front diff LSD started with a different part no. B16 for the Kodiak & 1XD for the Grizz the rest of the part no. was the same, the matching gear was the exactly the same between the two, maybe if it's a LSD or not, don't know, the only real different part no. was in the Sheave Weights, totally different part no. & that was it! This was for the 2017, earlier years may have something different in them idk, interesting that weights would make that much of a difference, well I feel better now :laugh:
