GFB pulley kits are designed to improve acceleration by reducing the rotational mass (inertia) on the crankshaft as well as parasitic loads from the driven accessories. The effect is similar to a lighter flywheel, and the engine feels more lively and willing to rev.\u003c\/p\u003e\r\n\u003cp\u003eWe know that people are sometimes concerned about possible adverse effects of lightweight pulleys and underdriving, but rest assured we have done our homework! The underdrive ratios have been optimised to ensure there are NO adverse effects on the performance of the accessories, and whilst it is true that some engine types do suffer harmonic issues from lightweight pulleys, we steer clear of those. The kits we release are thoroughly application tested and do NOT cause engine damage in the short or long term.\u003c\/p\u003e\r\n\u003ch3\u003eFitments:\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli class=\"vehicles\"\u003eSUBARU GT BL-BP EJ255 MY06-09\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eSUBARU XT MY09-13\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eSUBARU GT BL-BP EJ20T MY03-06\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eSUBARU STi MY08-13\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eSUBARU WRX MY08-14\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eSUBARU STi 2014-On (EJ25 Engine)\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eSUBARU GT MY03-06\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e","brand":"Go Fast Bits","offers":[{"title":"Default Title","offer_id":43023535964412,"sku":"GFB2014","price":315.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1128\/7276\/products\/go-fast-bits-subaru-wrxsti-08-14-liberty-gt-03-12-forester-xt-09-12-lightweight-engine-pulley-299358.jpg?v=1738947393","url":"https:\/\/jdcustomsusa.com\/ko\/products\/go-fast-bits-subaru-wrx-sti-08-14-liberty-gt-03-12-forester-xt-09-12-lightweight-engine-pulley","provider":"JD Customs U.S.A","version":"1.0","type":"link"}
