By holding a lower gear ratio for a longer stretch, it helps with hill climbing and quick pickup from a stop. It is one of the \u003ca href=\"\/collections\/gy6-150cc-parts\"\u003eGY6 150cc scooter parts\u003c\/a\u003e that can noticeably sharpen how your scooter responds. Riders who want stronger acceleration and a more efficient feel from their scooter should find it worthwhile.\u003c\/p\u003e\u003ch3\u003eImproved Acceleration and Response\u003c\/h3\u003e\u003cp\u003eThis spring raises the side pressure on the CVT belt, which cuts down on belt slip. When you open the throttle, the downshift should come in more quickly. It is made from heat-treated steel so it keeps its spring rate when temperatures run high, which supports consistent performance.\u003c\/p\u003e\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\u003cp\u003eSwapping the contra spring is simple, since it takes the place of the driven pulley spring. The spring carries a lot of tension, though, so work carefully. Use a clutch compression tool to hold the spring under control while you remove the large clutch nut.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate:\u003c\/strong\u003e 2000 RPM (Red)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Length:\u003c\/strong\u003e 154mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Diameter:\u003c\/strong\u003e 48.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter:\u003c\/strong\u003e 58.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Gauge:\u003c\/strong\u003e 4.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-treated steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e GY6 150cc (157QMJ) engine driven pulley; 2000 RPM red contra spring, 154mm long\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eGY6 150cc (157QMJ)\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhere it goes:\u003c\/strong\u003e part #4 on the driven pulley diagram for the GY6 150cc (157QMJ).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOther versions:\u003c\/strong\u003e For a GY6 Compression Spring rated at 1000 RPM (standard): \u003ca href=\"\/products\/compression-spring-gy6-1000-rpm-standard\"\u003eCompression Spring (GY6), 1000 RPM (Standard)\u003c\/a\u003e.
