While primary springs govern engagement and upshift force, the secondary driven spring controls belt pinch and backshift—determining how quickly your machine downshifts back into its peak powerband when modulating the throttle through deep powder, steep climbs, or aggressive riding conditions.\u003c\/p\u003e\n\u003cp\u003eFeaturing a \u003cb\u003e160 lb initial load and a 260 lb finish load\u003c\/b\u003e, this stiffer driven spring profile provides heavy side-pressure against the secondary sheaves to lock high-torque engines into the belt and eliminate power-robbing friction heat. Its higher finish rate enables ultra-fast backshift reaction times and prevents premature upshifting under high track resistance. Precision-manufactured from high-tensile spring steel, it resists heat sag and rate degradation under severe operating environments.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eKey Performance Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003e160-260 Driven Spring Rate:\u003c\/b\u003e 160 lb initial rate delivers aggressive, instant backshift response; 260 lb finish rate provides heavy side-pressure against high engine torque.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eUltra-Fast Backshift:\u003c\/b\u003e Instantly downshifts the secondary clutch when letting off the gas, putting immediate peak engine RPM and track speed right back on tap the moment you hit the throttle.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eHeavy-Duty Belt Clamping:\u003c\/b\u003e Maintains high side-pressure on driven sheaves, eliminating belt slippage, drastically reducing under-hood heat, and extending drive belt life on tuned or boosted builds.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePrevents Powerband Sag:\u003c\/b\u003e Holds back premature upshifting in deep snow or steep climbs, keeping the engine pinned in its ideal horsepower powerband.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eHigh-Tensile Alloy Construction:\u003c\/b\u003e Precision-wound spring steel resists heat-induced sag and rate loss, ensuring consistent performance throughout long, harsh rides.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSKU:\u003c\/b\u003e 05-160-260\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eInitial Load:\u003c\/b\u003e 160 lbs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eFinish Load:\u003c\/b\u003e 260 lbs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eComponent Type:\u003c\/b\u003e Secondary Driven Clutch Spring\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePrimary Function:\u003c\/b\u003e Manages driven clutch backshift speed, sheave side-pressure (belt clamp load), and upshift resistance under heavy loads\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bikeman Performance","offers":[{"title":"Default Title","offer_id":53717309849893,"sku":null,"price":27.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0749\/6436\/9701\/files\/05-160-260.webp?v=1788211635","url":"https:\/\/www.bikemanperformance.com\/products\/secondary-clutch-spring-160-260-sku-05-160-260","provider":"Bikeman Performance","version":"1.0","type":"link"}
