Tomioka Racing Shift Knob - Subaru 6-Speed

Tomioka Racing Shift Knob - Subaru 6-Speed

Tomioka Racing's shift knob is machined from Delrin -- a high-density acetal resin that combines high tensile strength with low moisture absorption.

Delrin Construction for All-Season Grip

Tomioka Racing's shift knob is machined from Delrin -- a high-density acetal resin that combines high tensile strength with low moisture absorption. Unlike aluminum shift knobs that get uncomfortably cold in winter and hot in summer, Delrin stays close to ambient temperature year-round, making it genuinely usable in all seasons. The material's density provides a solid, planted feel during fast shifts without the weight penalty of metal.
