{"product_id":"6061-aluminum-crankshaft-pulley","title":"6061 Aluminum Crankshaft Pulley","description":"The R Theory Motorsports Alternator Pulley offers a performance and aesthetic upgrade for your MX-5 Miata's engine bay. The blue anodized finish, complemented by laser-engraved markings, adds a custom, visually appealing touch.\n\nDesigned as a direct replacement, this alternator pulley aims to reduce the rotating mass within your engine. It fits all 1.8L MX-5 Miatas from 1994-2005. For 1.6L models, compatibility can be achieved by simultaneously swapping to a 1.8L crank pulley and belt. It is important to note that alternator pulley fitment can differ between NA and NB models; ensure this pulley matches your vehicle's specific alternator, even if an NB engine has been installed in an NA chassis.","brand":"R Theory Motorsports","offers":[{"title":"Default Title","offer_id":52871983104312,"sku":"NA-NB-APWP-PULLEY-SET","price":69.9,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/6061-aluminum-crankshaft-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
