You will have to file some to get the maxx tranny to fit. Then the four main tranny holes will have to be elongated to reach the maxx tranny holes. If you want more stability than four holes, you can drill four more.
Strobe slipper is a high performance alternative to the stock method (which melts under BL power). It is all explained
here. You'll need a few extra parts and the 51T spur, but that's all explained there as well. Note: make sure the slipper is tight or you'll wear out the strobe slipper pads.
Sliders are the driveshafts. The Revo uses tubes that slide in and out for easy removal, but due to the way the maxx tranny sits, those shafts will rub against the bulkhead. So, you'll need custom dogbones made. Mike can set you up.
As to a roller, I can set you up the the front/rear ends, custom dogbones/cups, and other stuff. It's used though. PM me if interested.
