Under drive pulleys increase engine output by reducing the draw of the engines accessories by slowing them down and reducing the HP they use. Additional and significant performance improvements can be seen by reducing the weight of the pulley versus the original pulley which is why we recommend the BBK CNC Machined billet aluminum pulley kits for maximum horsepower gains. ALL BBK pulley kits are designed as direct bolt on replacements for the current factory pulleys and retain full cooling and charging characteristics. BBK under drive pulley kits are vehicle specific and each kit comes with complete installation instructions and allow the re-use of existing serpentine belts.\u003c\/p\u003e\n\u003ch4\u003eFeatures \u0026amp; Benefits\u003c\/h4\u003e\u003cul\u003e\u003cli\u003eLightweight CNC Billet Aluminum Construction - Bolt On 8-15 Horsepower in Minutes\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTitle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBBK GM 5.0\/5.7 F-BODY\/GM TRUCK 3 PC UNDER DRIVE PULLEY KIT (ALUMINUM)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePulley Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBillet Aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePulley Color\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCNC Machined - Natural\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDirect Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBelt Included\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGrade Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePerformance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBelt\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRe  Uses Factory Belt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePulleys Included\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWater Pump, Alternator and Crank Pulley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003e⚠ WARNING:\u003c\/strong\u003e BBK Performance www.P65Warnings.ca.website_2100x759.jpg\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Guide:\u003c\/strong\u003e \u003ca href=\"https:\/\/sdda.semadata.org\/Standard\/BBK%20Performance%20Parts\/BBK-1598.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eDownload PDF\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation \/ Product Video:\u003c\/strong\u003e \u003ca href=\"https:\/\/youtu.be\/JlP5_dhWDnI\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eWatch on YouTube\u003c\/a\u003e\u003c\/p\u003e","brand":"BBK Performance","offers":[{"title":"Default Title","offer_id":45473140703276,"sku":"1598","price":279.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0687\/6007\/6332\/files\/1598_v1.jpg?v=1778970614","url":"https:\/\/carpartglobal.com\/products\/bbk-performance-parts-1598-1985-1987-gm-5-0-5-7-f-body-gm-truck-3-pc-under-drive-pulley-kit-aluminum","provider":"Car Part Global","version":"1.0","type":"link"}
