This is a driveline spacer, a precision-machined component used to set correct clearance or alignment in a driveshaft, differential pinion, or bearing assembly.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It fits between two components—such as a pinion gear and its bearing—to maintain the precise gap required for proper gear mesh and bearing preload. You typically replace it during a differential rebuild, pinion seal replacement, or when correcting driveline vibration caused by worn or incorrectly set spacing. It comes from Post Onsite’s driveline shop in Knoxville, so it’s likely intended for heavy-duty commercial truck or trailer applications.
