Weight And Feel That Transforms Every Shift
The GRMGRM380000 GrimmSpeed Shift Knob in stainless steel with a red finish is a favorite in the Subaru aftermarket for good reason. Its hybrid shape is comfortable whether you drive with an overhand or side grip style, and the added heft compared to the factory knob makes each gear change feel more direct and deliberate. Machined from solid stainless steel and laser etched with the GrimmSpeed logo, this knob threads on in place of the factory piece and fits both 5 speed and 6 speed Subaru manual transmissions right out of the box.
