The GrimmSpeed Stubby Shift Knob Black Delrin combines the short, fat profile of the stubby shift knob line with the lightweight character of Delrin construction. GRMGRM038012 is a popular choice for drivers who prefer a factory like shift feel but still want a cleaner, upgraded appearance over the stock knob. Machined from Delrin and finished in black, GRMGRM038012 keeps overall weight low while offering a comfortable grip for both overhand and side grip shifting styles. It threads directly onto manual Subaru shifters using the universal M12x1.25 pitch and includes a laser etched GrimmSpeed logo around the base.
