An engine’s camshafts must be set at their proper positions relative to the crankshaft in order to maximize horsepower. The Pro Series Exhaust Cam Gear for Honda's K-series 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. Pro Series Cam Gears feature precision-machined, hard-anodized steel teeth to reduce premature wear with a signature, six-bolt design that eliminates gear slipping. Skunk2’s lightweight design and CNC-machined, 7075-T6 billet aluminum construction reduces rotational inertia, resulting in increased engine response and acceleration. Skunk2’s adjustable cam gears have also been proven on race cars in the most extreme conditions for more than a decade.
