Zhigu's custom offroad wheels are built for extreme terrains, offering dual-phase forged 6061-T6 aluminum construction with 5mm-thick barrel walls and reinforced spoke roots. Customization includes 8-12 lug patterns, beadlock rings (3/16" 7075-T6 aluminum), and offsets from -44 to +25mm for lifted vehicles. The proprietary RockGuard finish combines powder coat with a 2mm-thick elastomeric layer, resisting impacts from 3" rocks at 30 mph. Internal stress-relief grooves reduce cracking risk by 40% during articulation. Load ratings exceed 3500 lbs per wheel, compatible with 35-40" tires. Each wheel undergoes 10,000 cycles of dynamic impact testing simulating 12" drop-offs. Optional integrated valve stem guards and anti-corrosion wheel weights ensure reliability in saltwater environments.
