This 3Racing hop-up replaces the stock rear hub carrier on TAMIYA M05 chassis with an aluminum unit that carries a fixed 2 degree offset. The part is intended for RC-scale adjustment of rear alignment, providing a metal alternative where the original component is plastic.
Installation is straightforward for those familiar with M05 maintenance: remove the original rear hub carrier, transfer bearings and mounting hardware, and refit the 3Racing unit to the stock locations. After fitting, check rear wheel alignment and suspension travel to confirm the intended 2 degree change matches your tuning plan.
Use this hub carrier when you want a repeatable rear geometry option for setup comparisons or when exploring handling changes. The 2 degree orientation is a tuning choice to alter rear tracking and balance during on-track testing or club sessions.
