This is an eyelet heim bearing from Schmidty Racing Suspensions which fit Works Performance shock eyelets. These heims are used in conjunction with step bushings to mount shock(s) onto the vehicle mounting points. They replace the older style metal-on-metal heims which had a groove on the outer race that Works Performance used.
These heims are also stainless steel and are Teflon lined. They are higher quality and have greater longevity over the older style metal-on-metal heims. Each heim bearing comes with two (2) replacement o-rings for the outer step mounting bushings.
You can also update your shocks if you have the thin-walled Delrin sleeve style bushings in your eyelets, and replace them with these heim bearings. That would require new heim step bushings to mount to your vehicle once the switch is made to the heim bearing. It is a bit more expensive up front, but the new bearings will last much longer!
