STi Copolymer Sphere
This shift knob is hand-made from solid acetal copolymer. This material is a hard plastic that will not absorb heat in the summer and won’t freeze in the winter like typical metal knobs. This provides an extremely comfortable knob all year long.
Additionally, this shift knob comes with a brass thread insert inside of it. This insert adds 25 grams of weight AND provides stronger brass threads compared to the standard copolymer sphere knob. This insert greatly reduces the chance of cross-threading or stripping the shift knob during installation and removal/re-installation in the future.
- Copolymer material will not get hot or cold!
- 2.0" diameter for comfortable size
- 105 grams weight for a quick, precise feel
- Smooth black luster finish, or satin white finish
- Internal threading provides a quick screw-on installation
- Strong strip-resistant brass threads
- Recess underneath allows for reverse gear function
