The Understated Upgrade That Changes Every Shift
The GRMGRM380001 GrimmSpeed Shift Knob in stainless steel with a black finish gives your shifter a heavier, more direct feel without shouting for attention. Its hybrid shape works equally well with an overhand or side grip, and the solid stainless construction adds noticeably more mass than the factory plastic knob. Each knob is laser etched with the GrimmSpeed logo and threads on in place of the factory piece, fitting both 5 speed and 6 speed Subaru manual transmissions with the correct M12x1.25 thread pitch.
