New-in-box Roadsafe replacement balljoint. These are supposedly OE Holden in a Roadsafe box. Kollar only sells in pairs, so if you just need one... here you go. Comes with a prevailing-torque class 10 lock nut, which should hold a bit better and be stronger than the nylock nut roadsafe supplies with it.

shipping is included because it's smol.
