Product Details

The Honda OEM Cotter Pin is a genuine factory replacement designed to secure compatible suspension, steering, and other mechanical assemblies on Honda and Acura vehicles. This essential retaining fastener helps prevent castellated nuts and other compatible hardware from loosening or backing off during normal vehicle operation.

Manufactured to Honda's original equipment specifications, this genuine cotter pin provides the correct factory design and dependable retention for applications requiring part number 90701-SX0-003.

Cotter pins are small but important safety-related components commonly used in assemblies where secure fastener retention is critical. Once installed through a drilled bolt or stud, the ends of the cotter pin are bent to prevent the associated nut from rotating beyond its secured position.

During suspension repairs, steering maintenance, or other vehicle service, cotter pins are typically removed to access the associated mounting hardware. Because they are designed for one-time use, a new cotter pin should be installed during reassembly.

Whether you're replacing worn suspension components, servicing steering hardware, or restoring factory mounting components, this genuine Honda OEM Cotter Pin provides a reliable factory-quality replacement.
