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 F20C/ F22C engines enable serious tuners to optimize horsepower and torque by being able to adjust camshaft timing in one-degree increments; allowing tuners to tailor the power curve appropriately.Skunk2 Racing Pro Series Cam Gears have laser-etched timing and directional marks that help to make precise camshaft adjustments that can be made quickly and easily. The F20C and F22C gears feature precision-machined steel teeth to reduce premature wear and utilize our signature six-bolt design that eliminates gear slip. We also retained the factory backlash mechanism for noise reduction and an OEM fit.+/- 10 Degree Range
