The Fidanza Aluminum Flywheel for 2004–2006 Scion xA and xB replaces the stock unit with a lighter, performance-focused aluminum assembly to reduce rotating mass and improve throttle response. It features a heat-treated friction plate for grip, a billet 6061-T6 or 2024-T4 aluminum body, replaceable hardened ring gear, military-spec fasteners, and a bolt-on replaceable friction plate. It’s 40–60% lighter than stock.
