The xl5 rustler gears will fit on the revo slipper, but I do not know if they will be too large in diameter and contact with the chassis, etc. Not sure if 48p will hold up, the mesh will have to be spot on, and no dirt or sand can come in contact with it. I would try the jato spurs and 32p pinions, like the emaxx pinions. A 54/12 or 58/13 would give the same ratio as the 9/40 and not require any bore reducers as the emaxx pinions are 1/8 bore. The 32p will hold up much better than 48p too.
