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. Read about the HKS SR20 Camshaft Step 1 256 EX below.

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.

SS-CAM (STEP1)
HKS SS-Cam are designed to fit unmodified cylinder heads with stock valve springs to be a simple bolt on cam kit that can give added performance without changing any other parts or the valve timing. By changing cams, cam duration and lift are altered making the ideal valve timing different. HKS SS-Cams have been tested on the engine bench to find the optimum valve timing and the knock pin has been relocated in a modified position to offer perfect valve timing, by simply replacing stock cams with no need for measurement or adjustment.

Non-Carb Legal.
As you can see in the graph, for 6000 RPM and above, the output is bigger, so for circuit drive you will have wide range of power band. And when you are driving you can feel the power till rev limit.
- By reviewing the profile, we could employ the 11.5mm STEP2 lift to the stock Valve Spring (maximum RPM: stock rev limit)
- If you want more than rev limit RPM changing the strengthen Valve Spring will let you have it. (maximum RPM:8000 RPM)
- In case there is no NVCS, we have set the valve timing for enough torque for the power at a high RPM. Depending on your need, with slide cam sprocket to adjust valve timing, you can have more control on torque.
