Delrin Construction: Stability and Low-Friction Surface
Cobb’s Delrin shift knobs are machined from Delrin (acetal resin) — an engineering polymer chosen for its dimensional stability, low-friction surface, and resistance to the hand oils, heat cycling, and UV exposure a shift knob experiences over its service life. Delrin does not absorb hand oils the way natural materials do and does not become slippery with heat. The two-tone construction uses a white or black primary body with a contrasting collar at the base, providing a clean visual distinction that complements a range of interior color schemes.
Non-Weighted, Color Options, and 6MT Thread Fitment
The Cobb Delrin knob is a direct-thread replacement — it screws onto the factory shifter shaft or Cobb short throw shifter shaft at the correct thread pitch for the application. No adapter is required. The collar color provides the secondary accent that distinguishes the white/red, white/black, and solid variants. At the correct torque, the knob seats firmly and does not rattle or loosen under normal driving conditions.
