Wilwood Cotter Pin

The Wilwood Cotter Pin is a hardware fastener used to secure retaining components in Wilwood brake and hub assemblies. A cotter pin (also called a split pin) is inserted through a drilled hole and its legs are bent over. This keeps nuts, axles, and retainers from backing off under vibration and load.

Key Features:

• Made for use with Wilwood disc brake calipers, hub assemblies, and related brake hardware
• Split-leg design locks into place once the legs are bent over
• Corrosion-resistant construction for dependable service in demanding braking applications
• Works as a replacement or service item when reassembling brake and hub components

Wilwood is known for high-performance brake components used in racing, street performance, and custom builds. Use a new cotter pin whenever you reassemble a retained fastener. This helps keep the assembly secure and reliable.
