CNC-machined highest-quality aluminum LEFT C-hub for ARS suspension system. Caster pre-set at 2 levels. Helps create more traction but in once yields more off-power steering and cornering speed versus standard back suspension system. Suitable for medium-traction conditions. Machined from premium Swiss 7075 T6 aluminum and black colored coated. Etched with "2L" for simple identification. Includes two nylon bushings. The C-hubs are available in standard caster angles (0°, 2°, 4°).
