HKS high performance camshafts are CAD designed to optimize torque and horsepower over the widest possible power band. Each camshaft application is offered in multiple profiles, each with their own lift & duration characteristics to suit various levels of tuning. Lower profiles offer substantial gains in power and a broad useable power band with little compromise in drivability. Higher profiles offer greater increases in power, but are tailored for the higher RPM range and racing applications.
HKS camshafts are not reground OEM units; they are machined from new billet cores which are constructed from a high nickel content iron alloy. By manufacturing all camshafts from billet cores, HKS is able to produce camshafts that equal or exceed the quality of the OEM units they are designed to replace. HKS camshafts are direct replacements and are designed to be compatible with the factory valve train components. However, due to the higher profile of HKS camshafts, HKS high performance valve springs are highly recommended, and required in certain applications.
HKS Adjustable Cam Gears allow fine tuning of the camshaft timing to maximize engine performance and tailor power characteristics for various driving conditions. Either with OEM or HKS Camshafts, adjustments can be made to tune an engine%u2019s power band to the optimum RPM range for a particular application. HKS Cam Gears are made completely of anodized Duralumin with nickle plated gear teeth except for applications with timing chains which utilize an aluminum slide with steel teeth.
HKS engineers chose Duralumin as the core material for HKS Cam Gears because its lightweight properties decrease drag on the engine. Precise valve timing can be adjusted and set within the range of ± 20° along a Vernier scale of 2° intervals. Each interval index is laser-etched into the Duralumin and \"A\" (advance) and \"R\" (retard) directional markers are also laser-etched on to the cam gear face.
