HKS Step 2 cams require upgraded valve-train.
These cams are aimed towards the midrange to top end.
Great for road race applications!
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 cores which are constructed from a high nickel content iron alloy. By manufacturing all camshafts from new 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 some HKS camshafts, HKS high performance valve springs are highly recommended, and required in certain applications.
