I switched from the RRP 48t spur to the HPI 52t metal spur from the XL and it's been holding up fine. The downside to the HPI spur is that it's thinner and only uses 1 slipper pad.

When I was running a Feigao 8XL geared 48/16 my motor temps were in the 180-190 range, but I was running stock size tires. Regardless of your gearing, you may be asking too much from the 9XL. Big wheels and tires and a 14lb truck are going to raise your motor temps. Put the stock tires and the 16t pinion back on and you should be good....

As long as you get a better battery. :)
