{"product_id":"1st-6th-carbon-synchro-set-1","title":"1st-6th Carbon Synchro Set","description":"The IAG Performance 1st-6th Carbon Synchro Set is engineered to enhance the shifting experience and reliability of your Subaru WRX STI's six-speed manual transmission. This essential upgrade addresses common issues arising from aggressive driving, such as worn or damaged synchronizers that can lead to gear grinding and further transmission damage.\n\nConstructed with superior Japanese brass, known for its high wear resistance and machinability, these synchros feature dual carbon friction surfaces. This design prolongs the lifespan of the synchro sleeve and gear teeth while enabling quicker and more precise gear engagement. The increased surface contact between gears and synchros reduces shift times and improves overall driver control.\n\nThis complete kit includes carbon-faced brass synchronizers for all six gears, eliminating the need to source individual OEM parts. The precision machining ensures a superior shift feel and robust strength, making it an ideal choice for both transmission rebuilds and performance upgrades. The set is compatible with 2004-2021 Subaru WRX STI models, with specific fitment noted for early 2006, late 2006-2007, and 2008-2021 model years.","brand":"IAG Performance","offers":[{"title":"Default Title","offer_id":52688779280696,"sku":"IAG-DRV-1044","price":549.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663694920.webp?v=1784895725","url":"https:\/\/store.motormia.co\/products\/1st-6th-carbon-synchro-set-1","provider":"MOTORMIA","version":"1.0","type":"link"}
