RZR170 Transmission Cover Output Gear #20

This is the genuine Polaris OEM output transmission gear, part number 0454557, position #20 on the RZR 170 transmission cover parts diagram. Factory tooth geometry, factory hardening, exact drop-in fit — the smart play for internal gearbox parts where tolerances actually matter.

Heads up on naming: this is the output gear, not to be confused with the output gear shaft (OEM #0454558) or the output shaft oil seal. If you're deep in a full transmission rebuild, it pays to inspect the whole gear train while the cover is off — we stock the ring gear (#18, 0454555), counter gear (#22, 0452527), counter shaft (#23, 0452526), bearings, and seals to do it right in one shot.
