• Please note that installing knurled ball joint bodies permanently alters and creates unrecoverable wear in the end forging and knuckle bores. Knurled bodies should only be used only as a last resort. We sell knurled versions to accommodatecustomers who previously had competitors' ball joints which may have enlarged or wore the mounting location installed and now are switching to Dynatrac.
