{"product_id":"hks-cam-pulley-evo-4g63","title":"HKS Cam Pulley Evo 4G63","description":"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’s power band to the optimum RPM range for a particular application. HKS Cam Gears are made completely of anodized Duralumin with nickel plated gear teeth except for applications with timing chains which utilize an aluminum slide with steel teeth.\n\u003cbr\u003e\n\u003cbr\u003eHKS 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.\n\u003cbr\u003e\n\u003cbr\u003eHighly durable and lightweight pulley\n\u003cbr\u003e\n\u003cbr\u003eUsing a super light duralumin (A2014) as its main material that the strength has increased by 50% and hardness by 30% (over previous version). This change in material has allowed the design change that has also allowed the unit to be substantially lighter (10% less load on RB engines) and increasing the engine reliability and power.\n\u003cbr\u003e\n\u003cbr\u003eNickel plating increases anti-frictional properties\n\u003cbr\u003e\n\u003cbr\u003eGear section is nickel plated for surface hardness increase (Hv: 350 → 500 (compared to older version)) to withstand strengthened timing belts and any foreign objects that may get caught between the gear and belt.\n\u003cbr\u003e\n\u003cbr\u003eCAM-SPROCKET\n\u003cbr\u003e\n\u003cbr\u003eAccurate valve timing control\n\u003cbr\u003e (angle adjustable)\n\u003cbr\u003e\n\u003cbr\u003eAs cam duration and other engine specifications changes, the ideal valve timing point will also change. As both intake and exhaust cam duration increase, the overlap amounts can be adjusted for optimum performance. All HKS Camshafts come with recommended valve timing which can be achieved by using these sprockets in conjunction with HKS camshafts. These sprockets are compatible with standard camshafts. \n\u003cbr\u003e (Note: Please ensure that when using these sprockets, timing chain cover must be installed.)","brand":"HKS","offers":[{"title":"Default Title","offer_id":48672881508648,"sku":"22004-AM001","price":139.2,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0715\/5767\/7352\/files\/hks-cam-pulley-evo-4g63-cams-valvetrain-794.webp?v=1717518331","url":"https:\/\/www.tegiwa.com\/products\/hks-cam-pulley-evo-4g63","provider":"Tegiwa","version":"1.0","type":"link"}
