All, I too bought the Bronco AU-04404 adjustable shocks for the rear of my 2017 500 HO EPS two up mechine. They fit perfectly both upper and lower eyes were a direct fit. They have plenty of adjustment as they came from the factory too stiff and I backed them off below the half way mark on the threaded body. They use counter tightened spanner locks to lock the shock in place. I'm 240 and wife is 133. With cooler and gear, nice ride. I do have different tires and rims, installed stock grizzly rims, tires on my rig as they are much lighter than OEM CFMoto. Just wanted to share. The modified rear shocks I made two years ago were lower in height, so the bronco's provided much needed suspension lift.
