Grand National Drive Flange ADW570

The ADW570 Drive Flange is designed for use with Grand National-style hubs with 5" x 5" or 5" x 4-3/4" bolt patterns where strength, durability, and precise fit are critical. Machined from lightweight, aircraft-grade billet aluminum, the ADW570 provides high strength while minimizing rotating weight.

The ADW570 features a pressed-in steel spline insert that improves wear resistance and helps extend spline life. Fully CNC-machined construction ensures a consistent, accurate fit, while the mill-scalloped design further reduces weight without sacrificing strength.

When used with Strange Oval axles, closely controlled spline tolerances provide a more uniform fit between the axle and drive flange, helping to extend spline life of both components. The ADW570 is compatible with virtually all 24-spline outboard axle ends.
