I don't know how many of you have inspected your slipper discs and aluminum pads but they gall up really bad and don't allow for much slip at all if any. I "THINK" this is adding to a lot of the front diff deaths. I saw the 1/10 Yeti robinson Gen 3 kit and it looked real beefy. The 1/10 Yeti and the Yeti XL have the same output shaft diameter. It is the same set up.... I have had Robinson Racing stuff in the past and now on my big block Maxx so I ordered it up. I purchased part # 1564. You will have to remove the trans and open up the output shaft hole in the plastic front trans case a little so the Robinson steel support hub clears. Now this spur is 64 tooth so you will need a smaller pinion. Stock is 68/15 which is 4.53:1 ratio. So I used a 14 tooth pinion...Thats a 64/14 which is a 4.57:1ratio. Pretty much the same..Just a touch lower gearing than stock. I also ordered a 13 tooth pinion which will be a 4.92:1 ratio. That's a bit lower than stock so we will see. I can't test it because of the three million feet of snow here in RI right now but it all fits and should work great. Here it is installed.
