This means using only the finest ultra-clean chrome silicon high-tensile steel alloys, executing proprietary heat treating and shot peening processes to ensure ultimate fatigue life and limit load loss.\u003c\/p\u003e \u003ceol\u003e\u003cp\u003eManley titanium retainers are manufactured to strict tolerances on the finest dual-spindle CNC machines to provide a superior, jewel-like finish. We use tough, certified, heat-treated aerospace-grade titanium bar stock. Retainer angles are held within 6' (minutes), which is one-tenth of a degree, and installed heights are held within .005\". Titanium retainers are a must for high RPM sport compact engines; their reduced weight allows the tuner to increase engine speed and avoid dangerous valve float without sacrificing reliability.\u003c\/p\u003e \u003ceol\u003e\u003cul\u003e \u003ceol\u003e \u003cli\u003eOuter\/Inner Diameter: 1.180\"\/.870\"\u003c\/li\u003e \u003ceol\u003e \u003cli\u003e.865\"\/.660\"\u003c\/li\u003e \u003ceol\u003e \u003cli\u003eSeat Pressure: 84 @ 1.315\"\u003c\/li\u003e \u003ceol\u003e \u003cli\u003eOpen Pressure: 199 @ .945\"\u003c\/li\u003e \u003ceol\u003e \u003cli\u003e245 @ .815\"\u003c\/li\u003e \u003ceol\u003e \u003cli\u003eStock\/Max Lift: .370\"\/ .500\"\u003c\/li\u003e \u003ceol\u003e \u003cli\u003eCoil Bind: .765\"\u003c\/li\u003e \u003ceol\u003e \u003cli\u003eRate (lbs\/inch): 310\u003c\/li\u003e \u003ceol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\n\n\u003c\/ul\u003e \u003ceol\u003e\u003cp\u003eSpring Part Number: 22185-16\u003c\/p\u003e \u003ceol\u003e\u003cp\u003eRetainer Part Number: 23185-16\u003c\/p\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e \u003c\/eol\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eBefore You Order\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e〇 Regarding Import Consumption Tax\u003cbr\u003eAt Shafutoya Shopping Site, we pay the import consumption tax incurred during importation on your behalf, so there will be no additional charges beyond the total amount paid at checkout.\u003cbr\u003e\u003cbr\u003e〇 \u003cspan\u003eConfirmation of Fitment\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eSince our entire product database is based on North American vehicles (USDM), please confirm whether or not parts can be installed on Japanese vehicles (JDM) before ordering.
