A simple, reliable, responsive steering assembly complements the ultra-reliable drive system and features a servo horn with integrated servo saver.
The self-bleeding, oil-filled shocks utilize an attempted and checked, coil-over design for simple maintenance and incredible handling. Their innovative rod end has a molded-in spring perch for additional durability. High chassis guards restrict the quantity of dirt and debris that can enter into the chassis tub.

With the power module removed, the slipper clutch can be reached quickly for modifications by securing three screws that attach the equipment cover. The power module design likewise makes sure that pinion and spur equipment mesh is best every time, utilizing numbered holes for different pinion equipment sizes.
A two-piece molding screwed to the truck's chassis acts as its electronics module, consisting of a waterproof radio box, servo mount, and ESC tray. The radio receiver mounts inside the radio box for defense from dirt and wetness. The ultra-compact ESC is screwed to the top of the module, enabling quick access to the on/off switch, while the servo mounts to the side. All three components can be gotten rid of together, rapidly and easily.
