The Yokomo D-139 upper A-arm shock tower is an aluminum conversion intended for the DriPack drift package on 1/10-scale RC drift cars. It replaces the standard front mount and provides an A-arm style upper mounting pattern compatible with the SSG front tower arrangement cited in the source.
Tuning role: by offering multiple upper mounting holes the tower lets you change camber gain and roll behavior to suit different drift setups. As a conversion item it modifies suspension kinematics to help drivers refine front traction and transition feel.
Compatibility and constraints: this component is specified for DriPack drift setups and must not be used with the D-102 Imadoki Conversion. Always double check chassis mounting geometry before fitting the D-139.
Installation notes: place the tower so all holes align and inspect steering and shock travel clearance before final tightening. Install with the correct fasteners and follow a measured torque sequence to prevent bending the aluminum mount.
