Special gauging fixtures allow dimensions to be held close to provide exact installed heights when assembling the cylinder head. APE titanium retainers are shorter than stock to provide additional retainer to valve guide clearance for high lift cams. APE is the only manufacturer of motorcycle retainers that also builds cylinder heads. We know how they have to fit, how they have to clear the bucket, etc. No other manufacturer can offer this expertise. You might think this extra precision is expensive.The fact that we are the manufacturer allows us to provide these super precision retainers at a price everyone can afford.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.mpsracing.com\/images\/products\/KPM\/60_60751.jpg\" alt=\"\" width=\"200\" height=\"123\" class=\"fltright\"\u003eKPMI® uses U.S. mill certified titanium bar for our retainers. KPMI® Titanium Retainers are engineered using advanced Finite Element Analysis (FEA) software. FEA stress analysis allows our engineers to lighten the retainer without sacrificing strength. All KPMI® retainers are inspected to insure correct fitment on the valve and on the spring. Correct fitment promotes longer component life and optimizes the Performance of the entire valvetrain.\u003c\/p\u003e","brand":"MPS","offers":[{"title":"71-60-60760   KPM Racing Spring Kit w\/ Titanium Retainers 0.490'' Lift Hayabusa","offer_id":57033282650272,"sku":null,"price":491.23,"currency_code":"USD","in_stock":true},{"title":"18-TVSR1300PRO   APE Titanium Retainers Hayabusa","offer_id":57033282683040,"sku":null,"price":245.95,"currency_code":"USD","in_stock":true},{"title":"18-TVSRS1000GSX   APE Titanium Retainers GSXR1000 01-04","offer_id":57033282715808,"sku":null,"price":245.95,"currency_code":"USD","in_stock":true},{"title":"18-TVSRS1000GSX-2   APE Titanium Retainers GSXR1000 05+","offer_id":57033282748576,"sku":null,"price":245.95,"currency_code":"USD","in_stock":true},{"title":"18-VG1300GSX   APE Valve Guides Hayabusa","offer_id":57033282781344,"sku":null,"price":217.24,"currency_code":"USD","in_stock":true},{"title":"18-VG1000GSX-4   APE Valve Guides GSXR1000 01-04","offer_id":57033282814112,"sku":null,"price":224.76,"currency_code":"USD","in_stock":true},{"title":"18-VG1000GSX-15   APE Valve Guides GSXR1000 2005+","offer_id":57033282846880,"sku":null,"price":224.76,"currency_code":"USD","in_stock":true},{"title":"18-vgk1400   APE Valve Guides ZX14","offer_id":57033282879648,"sku":null,"price":217.24,"currency_code":"USD","in_stock":true},{"title":"71-60-60620   KPM Valve Guide GSXR1000 07-08","offer_id":57033282912416,"sku":null,"price":6.0,"currency_code":"USD","in_stock":true},{"title":"71-60-60805   K P M Base Washers H T Steel Hayabusa","offer_id":57033282945184,"sku":null,"price":136.49,"currency_code":"USD","in_stock":true},{"title":"65-09289-05011   Suzuki Hayabusa Valve Seal Each OEM","offer_id":57033282977952,"sku":null,"price":8.0,"currency_code":"USD","in_stock":true},{"title":"1-0634   MPS Hayabusa and ZX14 Valve Seal (5.0mm)","offer_id":57033283010720,"sku":null,"price":4.2,"currency_code":"USD","in_stock":true},{"title":"65-09289-04003   Suzuki GSXR1000 01-04 Valve Seal Each OEM (4.0mm)","offer_id":57033283043488,"sku":null,"price":9.0,"currency_code":"USD","in_stock":true},{"title":"65-09289-04002   Suzuki GSXR1000 2005+ Valve Seal Each OEM (4.5mm)","offer_id":57033283076256,"sku":null,"price":8.0,"currency_code":"USD","in_stock":true},{"title":"1-0762   MPS GSXR1000 05+ Valve Seal (4.5mm)","offer_id":57033283109024,"sku":null,"price":4.2,"currency_code":"USD","in_stock":true},{"title":"65-12932-24f00   Suzuki Hayabusa Valve Keepers","offer_id":57033283141792,"sku":null,"price":2.5,"currency_code":"USD","in_stock":true},{"title":"65-12932-05C00   Suzuki GSXR1000 Valve Cotter\/Keeper 01-04","offer_id":57033283174560,"sku":null,"price":2.6,"currency_code":"USD","in_stock":true},{"title":"65-12932-32C00   Suzuki GSXR1000 Valve Cotter\/Keeper 05+","offer_id":57033283207328,"sku":null,"price":2.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/8432\/5024\/files\/60_60751.jpg?v=1779197163","url":"https:\/\/www.hardtimesparts.com\/products\/valve-retainers-guides-and-seals","provider":"Hard Times Parts","version":"1.0","type":"link"}
