{"product_id":"under-drive-crankshaft-pulley-kit","title":"Under-Drive Crankshaft Pulley Kit","description":"The Neuspeed Power Pulley Kit solves the problem of parasitic drag caused by engine accessories, which steal power from your drivetrain. By using a 20% under-drive ratio, the system allows the engine to spin the alternator and air conditioning compressor less aggressively, resulting in a dyno-proven gain of 5-7 horsepower and snappier throttle response.\n\nPrecision-machined from 7075 aluminum, each pulley is hard anodized for wear resistance and includes a specialized stainless steel ring to protect against oil seal abrasion. The complete kit weighs only 13 ounces, significantly reducing rotational mass compared to the 4-pound factory component.\n\nCompatibility includes 2014-up Audi A3\/S3 (8V) and TT\/TTS (8S), along with 2015-up VW GTI, Golf R, Golf, and Alltrack, plus 2018-up Tiguan, 2019-up GLI, 2019-up Arteon, and 2020-up Passat models with 1.8L or 2.0L TSI engines.\n\nProfessional installation is recommended for this kit. A factory-specific tool is required for proper removal and installation to ensure correct pulley seating and fastener torque.","brand":"Neuspeed","offers":[{"title":"Default Title","offer_id":52663092838712,"sku":"62.10.94","price":309.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687515032.jpg?v=1784323735","url":"https:\/\/store.motormia.co\/products\/under-drive-crankshaft-pulley-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
