This is the rear axle for the 2016 YETI. It is a different design than the original axle and it is round vs. the hex shaft that the original 2016 YETI came with, and it is made from 7075 material vs the 2016 out of 6061. It is a direct replacement and we suggest you purchase new rear titanium axle nuts with it and the “C” clips that stop the axle nuts from falling off.
