Weld Racing Alpha-1 Polished Wheels
Dominating all levels of drag and oval racing in the circuit, Weld Racing continues their legacy with yet another wheel addition—the Alpha-1 Series. Polished Alpha-1 rims utilize an exclusive hubless design in a forged aluminum construction, allowing for multiple backspacing and widths. Optimized for weight reduction, these wheels have been pioneered and proven in NHRA Pro Stock, Funny Car, and Top Fuel racing—setting a new standard for lightweight drag wheels specifically designed for drag racers competing in radial and small tire classes. Alpha-1 wheels are available in a variety of size and bolt pattern options.
