This aluminium rear suspension arm mount and gearbox support is an aftermarket hop-up designed to replace the factory B8 rear mount on the TAMIYA models listed. It fits as a direct replacement to reinforce the rear mounting area and create a sturdier interface between the suspension arm and the wavebox during typical use.
The item is compatible only with Thunder Shot, Thunder Dragon, Fire Dragon and Terra Scorcher. Manufactured from aluminium alloy and finished red, it installs in the same footprint as the original B8 part and uses the model's existing hardware.
Installation: remove the stock B8 rear mount and align the JAZRIDER mount with the gearbox and suspension pivots, ensuring flush seating and unobstructed suspension travel prior to final tightening. No modifications to servos, ESC, motor or gearbox internals are required. Fit this part to achieve a more consistent rear feel on compact or abrasive surfaces.
Servicing guidance: inspect mating faces for burrs following installation, maintain correct torque on mounting screws to prevent vibration loosening, and verify clearance to adjacent chassis components. After any change to rear geometry, re-confirm full travel clearance to the mount.
