Yokomo YD-2 aluminium ball diff kit
Yokomo have introduced an aluminium ball diff kit for the YD-2 series of RWD drift cars. The lightweight unit features aluminium outdrives that weigh in at only about one third of the weight of steel outdrives, making for lower rotational masses and thus quicker throttle response and a reduced gyroscopic effect. The set includes all needed parts and as well as thrust bearing and diff ball grease.
