A one-way clutch, including: an outer race; an inner race; and a rocker assembly. The outer race includes: a first outer race plate defining a first rocker pocket; and a second outer race plate non-rotatably connected to the first outer race plate and defining a second rocker pocket. The inner race is axially disposed between the first and second outer race plates. The rocker assembly is at least partly disposed in the first and second rocker pockets and includes a rocker arranged to contact the inner race, a spring guide including a spring arm, and a spring wrapped around the spring arm and urging the rocker in a pivot direction. The one-way clutch includes: a first annular thrust washer axially disposed between the first outer race plate and the inner race; or a friction-reducing coating adhered to the first outer race plate and facing the inner race.
