Those days are over thanks to SpeedFactory's 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; SpeedFactory 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 SpeedFactory uses for their 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\u003cstrong\u003eFitment:\u003cbr\u003e\u003c\/strong\u003eB-Series ALL B16, B17, B18, B20\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eReuse the rubber sleeve from the OEM spring if present (provides vibration damping for spring longevity).\u003c\/em\u003e\u003c\/p\u003e","brand":"SpeedFactory","offers":[{"title":"Default Title","offer_id":44446882005085,"sku":"SF-05-011","price":17.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1151\/0688\/files\/SpeedFactory-HD-Timing-Belt-Tensioner-Spring-B-Series-1.jpg?v=1778607113","url":"https:\/\/jhpusa.com\/products\/speedfactory-racing-hd-timing-belt-tensioner-spring-b-series","provider":"JHPUSA","version":"1.0","type":"link"}
