The DRC Drag Pak Mid Motor Top Shaft is a replacement for DRC1 chassis' equipped with the DRC Mid Motor Transmission (DRC-10002.1). The primary benefit of this design is it uses the factory Slash 22 tooth top gear (not included), or DRC top shaft gear (DRC-10008) and allows the use of Associated based spur gears and slipper clutch systems.

This top shaft can also be used with the DRC Maxim chassis as a tuning option if you want to use an optional slipper assembly like the Associated Lockout Slipper Clutch (ASC72026).
