An engine’s camshafts must be set at their proper positions relative to the crankshaft in order to maximize horsepower. The Pro Series Cam Gear Set for Honda's K20/ K24 engines enables serious tuners to optimize horsepower and torque by being able to further adjust camshaft timing, 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.
