Weld Racing 83B-512212F Alpha-1 Forged Beadlock Drag Racing Wheel 15x12

The Weld Racing Alpha-1 (83B-512212F) is a forged, three-piece drag racing wheel built for serious sportsman competitors. Engineered to bring WELD's proven Delta-1 technology into 15-inch sizing, the Alpha-1 delivers race-level performance with a 15" diameter and 12" width, making it ideal for wide radial and small tire drag racing applications.

At the heart of the Alpha-1 is WELD's exclusive hubless design, a technology pioneered and proven at the highest levels of NHRA competition — including Pro Stock, Funny Car, and Top Fuel. This hubless architecture removes unnecessary mass from the center of the wheel, reducing rotational weight where it matters most for acceleration and elapsed time.
