CNC-machined highest-quality aluminum RIGHT C-hub for ARS suspension system system. Caster pre-set at 4 amounts. Generates optimum traction. Suited to very-low-traction conditions. Although the wheelbase may become paid off a good deal using this environment, it really is vital that you lengthen the trunk wheelbase by going the trunk arms totally back. Machined from premium Swiss 7075 T6 aluminum and black colored colored coated. Etched with "4R" for easy recognition. Includes two nylon bushings. The C-hubs can be purchased in standard caster views (0°, 2°, 4°).
