This means utilizing only the best, super clean chrome silicon high tensile strength steel alloy and performing classified heat treatment and shot peen processing to insure the ultimate fatigue life and limit load loss.\u003c\/p\u003e \u003ceol\u003e\u003cp\u003eManley titanium retainers are manufactured in the very best dual spindle CNC machines to exacting tolerances rendering a superior jewel-like finish. We use rugged and certified, heat treated aerospace grade titanium bar stock. Retainer angles are held to within 6' (minutes) (this is a tenth of a degree) and installed heights are held to within .005\"! Titanium retainers are a must for your high RPM Sport Compact engine. Their lighter mass allows the tuner to turn higher engine speeds and still avoid dangerous valve float; without sacrificing reliability.\u003c\/p\u003e \u003ceol\u003e\u003cul\u003e \u003ceol\u003e  \u003cli\u003eO.D.\/I.D.:  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.\/in.):  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\u003c\/ul\u003e \u003ceol\u003e\u003cp\u003eSprings Part #:  22185-16\u003c\/p\u003e \u003ceol\u003e\u003cp\u003eRetainer Part #:  23185-16\u003c\/p\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\u003c\/eol\u003e\n\u003c\/div\u003e\u003c!-- tt-ap-content v1 --\u003e","brand":"Manley Performance","offers":[{"title":"Default Title","offer_id":67806107861311,"sku":"MAP MAN 26185","price":532.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1639\/5151\/files\/Manley-Performance-Pro-Series-Valve-Spring-Retainers-EJ20EJ25-26185.jpg?v=1792419239","url":"https:\/\/www.mobileigo.com\/en-ca\/products\/manley-performance-pro-series-valve-spring-retainers-ej20-ej25-26185","provider":"mobileiGo.com","version":"1.0","type":"link"}
