Product details
Left-hand vane orientation is required for this side of the HD scalloped rotor pair. Its smooth pad faces and 0.81-inch section combine with an 11.75-inch perimeter, making the exact casting and mount important when replacing a race brake ring. Established in 1977 by Bill Wood, Wilwood develops its range around complete disc brake systems. The Camarillo, California manufacturer designs and manufactures calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. Installation geometry, pad selection and braking duty should be considered together when choosing this component.
