Easy install
Had to get this to install a Fluidampr pulley on my WRX. Super easy install, just take your time to align it properly.
Great news – on this purchase, you'll enjoy a BuildBUX bonus of $0.53.
Fitment Information:
2019-2021 Subaru WRX (FA20DIT)
Features:
Grimmspeed's crank pulley hub allow 2019-2021 Subaru WRX owners to run their popular lightweight crank pulley. The OEM pulley design for the newer version incorporates a rear hub into the pulley itself, which gives you very limited options when looking to upgrade to an aftermarket pulley. By adding the crank pulley hub and a Grimmspeed LW crank pulley, you can take significant weight off of the rotating assembly which will allow it to rev more freely.
