The GrimmSpeed High Lift Hood Struts are the perfect way to ditch the OEM Subaru hood prop. GrimmSpeed meticulously designed their 02-07 Subaru WRX and STI High Lift Hood Struts using the highest quality materials so they will leave all other hood dampers left wanting. The GrimmSpeed High Lift Hood Struts allow you to lift the hood halfway providing adequate room to show off your WRX/STI's motor. But you can also open the hood all the way, and by "all the way" we mean, "All. The. Way." GrimmSpeed sourced large diameter, American made, hood struts then had them custom valved, so they pair perfectly with the weight of the 2002-2007 WRX/ 2004-2007 STI factory hood and allow you to open the hood 35% more than the factory hood prop does. It's almost vertical.
