Lightweight Shifts With an Upgraded Look
The GrimmSpeed Shift Knob Delrin gives Subaru drivers an easy way to upgrade the look and feel of their shifter without adding weight. GRMGRM038007 is machined from Delrin, an extremely durable thermoplastic, right in Minnesota, and keeps the same hybrid grip shape found on the stainless steel version while weighing a fraction as much. It is a favorite for drivers who want a factory like shift feel with a more finished appearance and a laser etched GrimmSpeed logo around the base. GRMGRM038007 threads directly onto the factory shifter using the universal M12x1.25 pitch shared by manual Subaru transmissions.
