When the Twin Cam® engine is running, the power pulses rock the tensioner shoe back and forth. On a single piston tensioner design, the natural shoe movement causes the hydraulic piston to momentarily unseat at the base, which interrupts the pressurized oil stream and introduces air into the hydraulic tensioner. Air will diminish or eliminate the pressure that the tensioner shoe places on the cam drive chains, allowing loss of valve train control - leading to “bounced” components including valves, spring collars, rocker arms, pushrods, lifters and camshafts. Red Shift® Dual Piston Cam Chain Tensioners are designed with shoe and hydraulic stability in mind, eliminating harmful air leaks in the cam chain tensioning system while dramatically improving overall valve train control and durability. \u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif;\"\u003e\u003cspan style=\"font-size: small;\"\u003e          What You Can Expect\u003c\/span\u003e\u003cspan style=\"font-size: small;\"\u003e \u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: small;\"\u003eRestores Critical Camshaft Timing Events for Both Cylinders\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: small;\"\u003eReduced Valve Train Noise by Increasing Chain and Valve Train Stability\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: small;\"\u003eImproved Throttle Response, Engine Acceleration and Engine Smoothness\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: small;\"\u003eIncreased Horsepower and Torque Throughout the Entire RPM Range\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: small;\"\u003eIncreased Valve Train Component Lifespan in High Performance Applications\u003c\/span\u003e\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Zippers Performance","offers":[{"title":"Default Title","offer_id":42328374116423,"sku":"ZP413-901","price":159.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/5953\/2615\/files\/413-901e_2.jpg?v=1766923284"},{"product_id":"zippers-performance-413-905s-red-shift-525-cams-shafts-harley-twin-cam-07-17","title":"Zippers Performance Red 525 Cams ZIP KIT Gaskets Bearings Harley 07-17","description":"\u003cp\u003e\u003cstrong\u003eRed Shift® 525 Zip Kit - Includes Cams, Gaskets, Cam Bearings\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003e525-HS:\u003c\/span\u003e\u003cspan\u003eExtremely popular Early (High)-Torque for 96” and 103” Twin Cam® engines with stock, unmodified heads.
