This aluminum rear suspension arm mount and gearbox support is an RC-scale hop-up intended to replace the B8 rear mount on compatible TAMIYA chassis listed in the product name. Built as a direct-fit component, its role is to stiffen the rear mounting area and provide a more rigid interface between the suspension arm and the wavebox assembly during typical buggy use.
Compatibility is limited to the chassis named: Thunder Shot, Thunder Dragon, Fire Dragon, and Terra Scorcher. The part is manufactured from aluminum alloy and is supplied in red; it installs in the same mounting location as the original B8 part and uses the radio-controlled model's existing hardware and fasteners.
Installation notes: remove the stock B8 rear mount and align the JAZRIDER mount with the gearbox and suspension arm pivots, checking for flush seating and smooth suspension travel before final tightening. No changes to servos, ESC, motor, or gearbox internals are required for fitment. For setup, consider this upgrade when you want a firmer rear end for consistent handling on hard-packed tracks.
Maintenance and tuning: inspect mating faces for burrs after installation, keep the mounting screws torqued to prevent loosening during running, and check clearance with nearby chassis components. If you adjust rear suspension geometry, re-verify that the arm clears the mount through full suspension travel.
