A-22490-5 or A224905 is a Hendrickson Spiralock hex flange nut, a genuine Hendrickson part from Pro Gear and Transmission. It is suspension hardware and is sold individually.
A locking nut like this one resists backing off, which helps keep chassis and suspension joints clamped through road vibration. It is a small piece of hardware, but a joint that loses its clamp load can work loose, so it is worth fitting the correct nut. Call us if you want help confirming it is the right one for your Hendrickson suspension.
