Wilwood 270-12127D Starlite Wide Disc Brake Hub - 55-XD 5

The Wilwood Starlite 55-XD hub delivers exceptional strength and performance for racing applications without the penalty of excessive weight. At just over 7 pounds, this advanced hub design represents a significant evolution of racing's most popular wide 5 hub pattern, featuring engineering improvements that enhance durability and reduce stress deflection.

Key Features:

• Bolt-on rotor mount plate design eliminates brake torque loading from the main hub body
• Transfers braking stress loads to the thicker, stronger section near the inner wheel bearing
• Measurable decrease in stress deflection compared to traditional hub designs
• Versatile rotor mounting: supports both fixed and dynamic mounting configurations
• Dynamic mount compatibility with t-nut rotor bolt kits isolates thermal expansion stresses
• Black e-coat finish seals castings and provides corrosion protection
• Wide 5 bolt pattern for racing applications
• Lightweight construction at approximately 7 pounds

What's Included:

• Hub assembly with rotor mount plate
• Bolts to attach mount plate to hub
• Snap Cap dust covers (front hubs)

Note: Rear drive flanges, bolt-on dust caps for using rear hubs in front locations, and rotor bolt kits must be ordered separately. The rotor mount plate design allows you to switch between fixed and dynamic mounting simply by changing bolt kits, providing flexibility for different temperature and racing conditions.
