Wilwood 170-14910 Dynamic Lug Drive Hat 7.77" Snap Ring 1.37" Offset

The Wilwood 170-14910 is a high-performance disc brake rotor hat featuring the innovative Big Brake Dynamic Lug Drive system. This advanced rotor mounting design eliminates traditional rotor bolts and allows the rotor to move independently of the hat during thermal expansion and contraction, eliminating thermally-generated stress at the rotor attachment points.

Key Features:

• 7.77-inch diameter with 1.37-inch offset configuration
• Bolt-free lug drive system allows independent rotor movement during heat cycles
• Large single snap-ring retention for quick rotor installation and removal
• Spring-loaded replaceable stainless steel inserts protect aluminum hat from wear
• Eliminates rotor distortion, pad knock back, and rotor drag
• Maintains consistent brake response and pedal feel
• Eliminates bolt hole alignment issues during rotor replacement
• No torquing or safety wiring of rotor bolts required

The Dynamic Lug Drive technology keeps rotors running flatter and truer by removing all thermal stress from attachment points. The spring-loaded stainless steel inserts in each lug-drive slot protect the lightweight aluminum hat from wear caused by brake torque loading. This design significantly simplifies rotor maintenance while improving overall brake performance and longevity.
