Wide 5 Drive Flange - Big Bearing ADW550

The ADW550 Drive Flange is designed for use with BIG BEARING / SMART HUB style Wide 5 hubs commonly used on Northeast Dirt Modifieds. Where strength, durability, and precise fit are critical. Machined from lightweight, aircraft-grade billet aluminum, the ADW550 provides high strength while minimizing rotating weight.

The ADW550 features a pressed-in steel spline insert that improves wear resistance and helps extend spline life. Flanged steel sleeve bushings in the mounting holes resist distortion for increased durability and longer service 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 ADW550 is compatible with virtually all 24-spline outboard axle ends.
