CNC Custom 5 Bolt Pattern Quick Release Steering Wheel Hub Adapter for Racing Car. CNC-machined from premium aluminum and high-tensile alloy steels to guarantee ultra-precise tolerances, eliminating steering play entirely. Features a unique tapered clover/D-shaped core to provide effortless, multi-directional orientation and zero-galling compared to traditional splined hubs. Engineered with a standard 5-bolt steering wheel mounting pattern to seamlessly fit major racing steering wheel brands with exact bolt-circle alignments. We offer comprehensive custom processing based on your technical drawings or physical samples, allowing specific adjustments to heights, bolt spacing, or core profiles. Our factory delivers an integrated, one-stop solution encompassing raw material sourcing, CNC milling, hard anodizing surface finishing, and safety inspections. The structure is extensively lightened through CNC weight-reduction pockets without compromising the high-torque rigidity needed for competitive racing. Treated with a heavy-duty, wear-resistant hard-anodized black finish to resist sweat, oxidation, and constant frictional scratching from daily track use. Our advanced CNC infrastructure allows us to offer global B2B buyers highly competitive factory-direct pricing and reliable lead times for small custom batches or mass production.
