HKS high performance camshafts are CAD designed cams to optimize torque and horsepower over the widest possible power band. Each HKS camshaft is offered in multiple profiles, each with their own lift and duration characteristics to suit various levels of tuning. Lower profiles offer substantial gains in power and a broad usable power band with little compromise of drivability. Higher profile camshafts offer greater increase in power but are accustomed for higher RPM range and racing applications.
