Billet Aluminum Crank Pulley

Constructed from Billet 6061-T6 aluminum and finished with a durable black anodization, this pulley is built to withstand demanding under-engine conditions. Designed with precision, the Lightweight Main Pulley maintains the factory pulley diameter. This ensures that the accessory belt is not under-driven, which prevents potential electrical behavior issues often associated with lighter pulleys. It also preserves the stock drive belt function. This pulley is compatible with a range of Subaru models, including the WRX (2002-2014), STI (2004-2021), Legacy GT (2005-2009), Outback XT (2005-2009), and Forester XT (2004-2013), specifically for EJ25 turbo models. However, it has not been confirmed to work on H6 engines. It is also noted that this pulley is not compatible with 2010 and newer Legacy models.
