An engine's camshafts must be set at their proper positions relative to the crankshaft in order to maximize horsepower. Skunk2 Pro Series Cam Gears for Honda's F20/22C engines enable serious tuners to optimize horsepower and torque by being able to adjust camshaft timing one-degree increments, allowing them to tailor the power curve appropriately. Thanks to laser-etched timing and directional marks precise camshaft adjustments can be made quickly and easily. Pro Series Cam Gears feature precision-machined steel teeth to reduce premature wear and utilize our signature six-bolt design that eliminates gear slip. Skunk2 F20/F22 C cam gears retain the factory backlash mechanism for noise reduction and OEM fit. Skunk2's adjustable cam gears have also been proven on race cars in the most extreme conditions for more than a decade.
