The effect is similar to a lighter flywheel, and the engine feels more lively and willing to rev.\u003cbr\u003e\u003cbr\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, 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.\u003cbr\u003e\u003cbr\u003eGFB products are manufactured in Australia and the company is accredited to ISO 9001, which ensures their products meet stringent quality requirements at all stages of manufacture.\u003cbr\u003e\u003cbr\u003eGFB have Australia's best performance turbo management solutions.","brand":"Bapcor","offers":[{"title":"Default Title","offer_id":47455621447933,"sku":"SBX-P6888848","price":578.76,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/8396\/7485\/files\/2001_web.jpg?v=1777191399","url":"https:\/\/krenbits.com\/products\/sb-gfb-2-piece-underdrive-pulley-kit-2001","provider":"Kren Bits","version":"1.0","type":"link"}
