Hot Bodies 2-Way Diff
Coming as standard with the Cyclone TC, the new HB 2-Way Diff is available as an option for the standard Cyclone. This unique drivetrain part gives you the option of having one part act as a super-durable one-way diff as well as a locking spool, giving you the best of both worlds and letting you set up your car for both tight, twisty tracks and wide, sweeping courses. Comes complete with everything necessary for assembly and installation.
