Buying Guide: Key Purchase Considerations
- Thread compatibility: Confirm the knob’s thread size matches your shifter. 9/16-18 is common on many muscle-era transmissions, but universal knobs often require adapters.
- Material and grip: Aluminum provides durability and a cool touch; aftermarket options may use aluminum with an acrylic or rubberized top for grip.
- Shifter style and compatibility: If you have a reverse lockout or a stock shifter, ensure the knob supports that feature or is sold as a knob-only replacement if needed.
- Installation considerations: Some knobs require set screws or adapters; others screw directly onto the shift shaft. Verify the installation method and torque requirements.
- Aesthetic fit: Consider whether you want a classic, modern, or marble-look knob to match your interior or restoration goals.
