The Sonnax wide reaction sun gear bushing 77010-01 is one-and-a-half times the width of the OE version and fills the entire sun gear bushing groove. This wider bushing maximizes support. The bushing is steel-backed bronze that is precision machined to provide minimal clearance with the mating shaft.
