HKS high performance camshafts are CAD computer designed to optimize torque and horsepower over the widest possible powerband. Each camshaft application is offered in multiple profiles, each with their own specific duration and lift characteristics to suit various levels of tuning. Lower profiles offer substantial gains in power levels and a broad useable powerband throughout the RPM range with little compromised in driveability. Larger profiles offer greater increases in power levels, but are tailored for higher RPM range use and race oriented driving characteristics. Increased performance from the HKS camshafts are achieved by widening the degree of opening of the valve, which increases power in the higher RPM range, and by increasing lift, which raises overall torque output. All HKS camshafts are made from new billets of high nickel content iron alloy, not reground stock units, therefore equaling or exceeding the OE units they are designed to replace in terms of quality and workmanship. The camshafts are direct replacements and are designed to be compatible with the factory followers and valve springs. HKS also offers high performance valve spring sets for limited applications that can benefit from stiffer springs when using Larger profile HKS camshafts. Normally with a good tune, camshafts can provide additional 20+ whp on turbocharged applications.
