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 Hondas 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.
