Specifically produced for SO series 2WD off-road cars, this aluminum rear hub carrier supersedes the standard resin piece to increase component rigidity and reduce deformation during heavy use.
In practical running the aluminum carrier offers greater resistance to bending during hard landings and forceful acceleration, which helps preserve setup and maintain handling consistency lap after lap. The same height insert compatibility is maintained, so you can keep your roll-center and skid-angle choices.
Because the bores are finished accurately, fitting fresh bearings is recommended; reused bearings pressed into tight fits may be difficult to extract later. The part focuses on reliability and tunability rather than visual changes.
This aluminum upgrade is for racers who prioritise a firmer rear end and consistent handling; install new bearings and verify roll-center settings after fitting to get the best durability and performance.
