Hughes Performance Billet Planetary Gear Sets are ideal for modern big-displacement engines. Hughes Performance Billet Planetary Gear Sets are extremely stout gear sets featuring new gears, a new forged ring gear, a new forged planetary housing, new 9310 pins, new washers and needle bearings. The forged billet output shaft from the Hughes Performance Billet Planetary Gear Sets offer excellent torsion memory, meaning you can twist it, but it is near impossible to break! Hughes Performance Billet Planetary Gear Sets are available in long, medium and short versions. Many of Hughes Performance's competitors only offer Planetary Gear Sets with steeper gears, but Hughes Performance knows 1.76’s provide superior torque output for modern high-output motors.
