Bent Springs trail 1039 and went about half way up with just the wife after installing new axles. A pretty rugged climb in first gear all the way to where we turned around to save for next weekend yxzmonster. Stock 2016 gears with Weller ecu flash, tubeworks clutch oil mod with jutter spring removed and full size oem clutch plates all the way thru which makes it easy to change out clutch without removing basket/drum. Grabs and climbs like a billy goat with plenty of power at low rpm’s, drops as low as 1500 and i can power right up. Who dares to say the yxz will not climb? I really need video feed as the wife will not take pictures for some reason when we are climbing up hill at a good pace.
