I figured I would start a thread on what it takes to install the 2013/14/15 1,000 and 2015 800 XMR rear diff into the G2 chassis. This is the bigger Differential with more pinon support and Hypoid gears.:clapsmilie:
For 800 single seat bikes (renegade or outlanders) the 2015 800 XMR "short" drive shaft 703500858 is the easiest swap.
For 2 up bikes it is the same thought process, just using the 13-15 1000 xmr drive shaft will work for 1000 bikes. For 800 bikes you could use the 1000 shaft and swap your input "gearbox" side yoke.
The final way for any g2 bike is to shorten your shaft 1.75" and swap out the output "differential" side yoke for the xmr yoke.
