This Arrowmax AM-931017 busing, sized 6.35x9.5x5.5, is intended as a replacement journal for pan car geardiff assemblies used on 1/12 and 1/10 platforms. It provides the internal sliding surface that supports diff shafts and reduces sideways play.
Intended application: the component fits housings that accept a 6.35mm inner shaft and supplies a controlled bearing surface to maintain gear mesh and steady rotation under load. It is a routine service item for rebuilds or when worn bushings cause slop or inconsistent performance.
Workshop notes: remove the diff housing per your chassis instructions, check bore condition and mating parts for wear, press the new bushing flush into the bore, then reassemble and confirm smooth rotation with minimal endplay. Regular inspection keeps diff feel consistent for tuning and race prep.
