New OEM Canam Commander 800 or 1000 rear driveshaft. We install the wear sleeve and protector to make it a straight forward install for you! This is an OEM can am shaft, do not confuse this with sub grade Chinese products. If you have a 2011-13 commander 800 or 1000, please understand the 2014-new commander rear propshaft will not fit! They have a different rear differential. We here at CPG understand the newer shafts are much cheaper, we do not know why there is such a price difference. *Will not fit Commanders with Electric Unlocking rear differentials (this is a rare option, you will have a switch on the dash) 20 spline gearbox end yoke 18 spline differential end yoke Roughly 6 1/4? center of weld to center of weld.
