This JAZRIDER JR-THS09-RD kit supplies a rear suspension crank assembly and a coordinated red ball rod set for use with the TAMIYA Hotshot RC chassis. The parts correspond to the Hotshot E2, E4 and E6 positions and are offered as straightforward replacement pieces for repair or organised spare use.
Installation follows the usual Hotshot procedure: remove the rear arm assembly, move any required bearings across, and secure the ball rods onto the crank ends with the original ball studs. Cycle the suspension to confirm smooth travel and that no binding occurs at full compression or droop before finalising fastenings.
Use the kit to restore factory pivot geometry after long service life or as a like-for-like spare to maintain consistent rear behaviour during setup changes on Hotshot models.
