Aluminum RIGHT C-hub is designed & recommended for use within high-traction conditions. Increases steering out of the part, and makes the car more stable going into corners. Roll center position can be easily and quickly adjusted by inserting various thickness of shims on the top of the caster block between your block as well as the vertical ball stud. The caster blocks feature large spaces for faster & easier assembly/disassembly associated with the CVDs. The entire CVD installation can be simply inserted/removed through the C-hub without the need for disassembly. The big spaces also prevent collision of the CVD with the C-hub in serious crashes. CNC-machined from premium Swiss 7075 T6 aluminum. Additionally black colored coated and laser etched. Use with matching #322221 Aluminum C-hub Left. Fits XB2, XT2, SCX
