This Gen III hub features precision 46-tooth splines designed for exact fitment with DMI and Winters 46-spline axles, delivering quality performance in sprint car and racing applications.

Key Features:

• 46-tooth splined inboard hub design for DMI and Winters axles
• 5-bolt rotor plate attachment for enhanced stiffness and rigidity
• Compatible with 8 x 7.00" bolt pattern rotors
• Improved rotor plate design with optimized OD to ID dimensions
• Thicker rotor plate material for extended service life
• User-friendly assembly and disassembly process
• Rotor plate can be removed without removing axle spline saver
