Wilwood 170-15977 Big Brake Dynamic Lug Drive Rotor Hat

The Wilwood 170-15977 is an innovative Big Brake Dynamic Lug Drive rotor hat that revolutionizes rotor mounting through a bolt-free attachment system. This advanced design allows rotors to move independently of the hat during thermal expansion and contraction, eliminating thermally-generated stress at attachment points for superior performance and longevity.

Key Features:

• Dynamic lug drive system eliminates traditional rotor mounting bolts
• Allows independent rotor movement during heat cycles to prevent thermal distortion
• Spring-loaded stainless steel inserts protect aluminum hat from wear during brake torque application
• Single snap-ring retention system for quick rotor installation and removal
• Eliminates pad knock back, rotor drag, and bolt hole alignment issues
• Maintains consistent brake response and pedal feel throughout use
• Lightweight construction reduces rotating mass on the driveline
• No torquing or safety wiring of rotor bolts required

This rotor hat is engineered for high-performance braking applications where thermal management and precision are critical. The innovative lug drive design keeps rotors flatter and truer throughout their service life, while the replaceable stainless steel inserts ensure long-term durability. Compatible with Wilwood's stainless alloy disc rotors designed for the Dynamic Lug Drive system.
