GrimmSpeed Gates Stretch Belt Pulley Adapter - WRX 2008-2014 / STI 2008-2017 / More
GrimmSpeed created a unique adapter that allows you to use the Gates Stretch Belt Kit for the 2008+ Impreza with the GrimmSpeed Pulley. Other manufacturers tell you to use the Gates kit on the 2008+ Imprezas but they fail to mention that the Gates Kit will not work on their pulley. They have solved this problem for their pulley.
Pulley is not included.
