OEM Honda Ball Joint Castle Nut & Cotter Pin Kit – Civic, Accord, CR-V, Odyssey, Fit, Pilot & More

Genuine OEM Honda Ball Joint Castle Nut and Split Pin Kit

This OEM Honda ball joint castle nut and split pin kit is commonly used when servicing the front suspension, lower ball joint, control arm, or knuckle assembly on many Honda models. When a ball joint is separated for repair or replacement, the cotter pin/split pin should not be reused, and replacing the castle nut is a smart way to keep the repair clean and secure.

This kit is ideal for suspension repairs, ball joint replacement, control arm service, or replacing missing, worn, rusted, or damaged ball joint hardware.

Why replace this hardware?

The castle nut secures the ball joint stud, while the split pin/cotter pin locks the nut in place to help prevent loosening. Honda parts catalog sources commonly identify this type of pin as a lower ball joint cotter pin or suspension ball joint lock pin, and some OEM catalog notes state that these pins cannot be reused/reinstalled.
