Will this fit my shift collar without modification?

This knob is engineered as a direct replacement for Honda and Acura 5-speed transmissions. Test-fit before final installation to confirm collar match — threading specifications not confirmed in product data.

Does this come with a collar adapter or retaining ring?

Only the shift knob is included. Check your OEM hardware — most applications reuse the existing collar and retaining ring from your factory knob.

What's the installation process?

Standard swap: unscrew your factory knob, remove the collar and retaining ring, transfer them to the new knob, and install. Hand-tighten to secure — no special tools needed.
