Those days are over thanks to our solution to this common problem.\u003c\/p\u003e\n\u003cp\u003eThe SpeedFactory Racing B-Series HD Timing Belt Tensioner Spring is made from durable \u0026amp; corrosion resistant 302 stainless steel and is over 7x stronger (the OEM spring is very weak \u0026amp; we found the need for a much higher spring rate).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eThis high-quality spring gives your timing belt the proper tension level for high-performance and racing applications, especially when using a heavy-duty racing timing belt (such as TODA or Gates Racing) which are much stiffer \u0026amp; stronger than an OEM type belt.\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNot enough tension (OEM spring) and you get excessive belt deflection with poor cam timing control and a high risk of jumping teeth resulting in expensive valve damage or worse.\u003c\/p\u003e\n\u003cp\u003ePulling on the tensioner with a hook to try and get enough tension has been a work-around but yields non-repeatable results at best and easily results in over-tightening which can cause undue stress on the belt and cam journal wear issues.\u003c\/p\u003e\n\u003cp\u003eThis is what we use for our own top level engine builds with no other form of additional tensioners - race proven up to 12k rpm even with violently disrupting the engine via ignition shift cuts and rev limiters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNo timing belt skipping, no cam journal wear issues, just reliable and consistent belt tension that works!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eLifetime warranty against manufacturing defects.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.speedfactoryracing.net\/search?type=product\u0026amp;q=timing+belt\" title=\"High Performance Timing Belt Options\"\u003e\u003cspan style=\"text-decoration: underline; color: rgb(43, 0, 255);\"\u003e\u003cstrong\u003e\u003cem\u003eCLICK HERE FOR OUR HIGH-PERFORMANCE TIMING BELT OPTIONS!\u003c\/em\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"SpeedFactory Racing","offers":[{"title":"Default Title","offer_id":51101478617387,"sku":"SF-05-011","price":17.84,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/9124\/9973\/files\/springkit-02.jpg?v=1753992911","url":"https:\/\/ebtecautomotive.com\/products\/speedfactory-racing-b-series-hd-timing-belt-spring","provider":"EBTEC AUTO","version":"1.0","type":"link"}
