The goal of the OS Giken Close Ratio Gear Kit is to reinforce the transmission internal components while maximizing an engine's potential by providing custom gear ratios for performance driving.\u003c\/p\u003e\n\u003cp\u003eEach OS Giken gear component is designed and created from high-quality forged materials, and then undergoes hard shot peening, resulting in increased strength and durability. Furthermore, the gears are helical-cut rather than straight-cut to maintain quiet, smooth operation, providing full comfort for street driving as well as reliability for racing.\u003c\/p\u003e\n\u003cp\u003eOS Giken close-ratio gearsets offer greatly increased gear strength, along with closer gear ratios to suit racing applications. The retention of normal synchromesh parts and a helical gear design means the gears are still almost as quiet as a standard gear set, so this is an excellent upgrade for street-driven vehicles too.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0508\/9312\/7879\/files\/OS_GIKEN.jpg?v=1781759559\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3 Speed Gear Set\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eOS Giken 3sp ratios: \u003cspan\u003e1st: 2.714 2nd: 1.742 3rd: 1.267 4th: OEM 5th: OEM\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eStandard ratios: 3.483, 2.015, 1.391, 1.000, 0.806\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eVehicle Compatibility:\u003cbr\u003e\u003cbr\u003e- Mazda FC3S RX-7 13BT\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e \u003cspan\u003ePlease prepare genuine Mazda part numbers R502-17-316 (spacer) and R502-17-306A (roller bearing). \u003c\/span\u003e\u003cspan\u003eSince it is a genuine replacement, please refer to the assembly manual.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"OS Giken","offers":[{"title":"Default Title","offer_id":43279213756615,"sku":"OSGEARSET3SPD-R5M-D","price":3734.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0508\/9312\/7879\/files\/os-giken-3-speed-cross-gear-set-r5m-d-fits-mazda-rx-7-fc3s-13bt-transmission-747.png?v=1781764927","url":"https:\/\/justjap.com\/products\/os-giken-3-speed-cross-gear-set-r5m-d-fits-mazda-rx-7-fc3s-13bt","provider":"Just Jap","version":"1.0","type":"link"}
