This is the WPL transfer case I replaced the stock gear motor with a 485rpm 20:1 servocity economy gear motor..but the out put shaft was a little long so I drill out a little head space in the transfer case, the walls of the case are pretty thick and I was able got get enough room to mount the new gear motor but it was still kind of underpowered.. So I used a 56rpm 171:1 gear motor and replaced the motor with a 25turn Traxass 7575 and it seems to have the torque and speed I wanted
