{"product_id":"6061-t6-aluminum-crank-accessory-and-power-steering-pulley-kit","title":"6061-T6 Aluminum Crank Accessory and Power Steering Pulley Kit","description":"The Macht Schnell Underdrive Pulley Kit offers a significant increase in rear-wheel horsepower and torque for your M3, M5, or M6, or a more modest gain for your M3. Engineered from robust 6061-T6 aerospace aluminum, these pulleys are built for strength and lightness. They replace the stock Crank Accessory and Power Steering Pulleys, reducing parasitic drag from accessories to maximize performance. The kit features a DualDrive design that minimizes the effect on accessory speeds while maintaining proper cooling temperatures and adequate alternator speed for sensitive control modules. This ensures your vehicle's reliability both on and off the track.\n\nAfter precision machining and engraving, the pulleys undergo a T3 hard-anodizing process, enhancing their strength, corrosion resistance, and overall durability. The installation is a straightforward bolt-on procedure, and the kit comes complete with new belts, ensuring you have everything needed for a smooth upgrade. All factory crankshaft dampening and harmonics are undisturbed by this modification.","brand":"Macht Schnell","offers":[{"title":"Default Title","offer_id":52662860644664,"sku":"10.00.010","price":349.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687075817.webp?v=1784321601","url":"https:\/\/store.motormia.co\/products\/6061-t6-aluminum-crank-accessory-and-power-steering-pulley-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
