Taller gears in the transmission reduce the overall reduction factor of the gearbox. If the engine is powerful enough to pull the taller gears, this modification will also raise top speed. The original gears in some models are quite short; this is where you can gain some MPH even with original cylinders. Different from common gear units, the ones from Stage6 come pre-pressed and are available at an unbeatable price. Simply replace the old gear unit with the new one – and that’s it
