Performance
While the 2015-18 Subaru WRX utilizes a standard crank pulley design, which can easily be switched out with the current GrimmSpeed FA Lightweight Pulley, the 2019-21 WRX is a different story. 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. Our Engineers saw this as an opportunity for a plug-and-play solution and got to work. This new GrimmSpeed FA Lightweight Crank Pulley Hub allows 19-21 WRX owners with the heavy OEM one-piece crank pulley/hub assembly to use our popular lightweight crank pulleys. Machined from A311 Steel Alloy and zinc-plated, this beautiful, extremely durable hub will ensure that the oil pump and crank pulley are driven without danger of leaks or failure. Coupled with our LW Crank Pulley, this will take significant weight off the rotating assembly of your FA engine, allowing it to rev more freely. 19-21 WRX Owners can now be among the tens of thousands using a GrimmSpeed-brand Crank Pulley!
