All APEXi camshafts are precision engineered on CAD systems delivering unparalleled performance. All cams are designed for competition high horsepower output. Few companies possess the technology to develop high quality cams. The GT camshafts have been primarily developed for optimal matching with our AX turbo series or comparable sized turbo. The VMAX SPL series are an aggressive camshaft lineup made for the RB26DETT Skyline GTR engine. These camshafts have already proven themselves on our 8 second 1100HP V-MAX test car.
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.
Skunk2 Racing valve springs are made from the hightest quality chrome silicone wire from Japan. These valve springs are designed from experiences in touring car and drag racing. The dual interference fit valve spring design prevents harmonic spring surge and valve float. All valve springs are race tested and proven and can be used with both forced induction and naturally aspirated engines.
Skunk2 Racing retainers are CNC machined from super-strong aerospace quality titanium and are designed to significantly reduce overall valvetrain mass. They are machined to extremely close tolerances in order to ensure properly installed spring heights and pressures.
Made from SAE EV8 stainless one piece forgings which are heat treated using a proprietary heat treatment process. After CNC-machining and swirl polishing, a PVD black nitride coating is applied to reduce friction and increase wear resistance. Skunk2 Racing valves are lightweight, durable, and offer excellent heat and corrosion resisitance. They are available in stock and over sizes in both standard and high compressions styles.
