Made for 2WD off-road SO series models, this aluminum rear hub carrier replaces the standard resin unit to boost structural stiffness and deliver steadier handling.
On the track the stiffer aluminum carrier limits flex during sudden loads such as hard landings or aggressive acceleration, helping the chassis maintain line through jumps and tight turns. The carrier accepts the same height insert as the stock part, so roll center and skid angle adjustments remain available without altering mounting geometry.
Final machining improves fit accuracy, so it is advisable to fit new bearings when installing this hub carrier; pressing in worn bearings may complicate later removal. As an upgrade component it emphasizes predictable handling and tuning flexibility rather than cosmetic change.
As an aluminum replacement for the stock resin carrier, this part is intended for drivers seeking firmer suspension feel and more consistent line holding; fit fresh bearings and recheck roll-center settings after installation to tune handling.
