Zhigu's aftermarket auto wheels provide performance upgrades for everyday drivers, featuring A356-T6 cast aluminum construction with T6 heat treatment for enhanced strength. The low-pressure casting process ensures uniform density, while CNC machining provides precise tolerances (±0.15mm). Available in 15-20" sizes with 5-8 lug patterns, they support most passenger vehicles and light trucks. A 10-step finishing process includes e-coat primer, powder coat, and UV-resistant clear coat for 500-hour salt spray resistance. These wheels are 18% lighter than steel OEM alternatives, improving fuel efficiency and handling. Load ratings range from 1,800 to 3,200 lbs per wheel, suitable for daily commuting to weekend adventures.
