Gearshift Knobs & Shifter Accessories FAQs

How do I choose a gearshift knob for my semi-truck?

Start with your shifter and transmission specifications, then choose the knob style and finish. Compare the listed transmission speeds, adapter requirements and included components. A truck make or a similar-looking knob alone does not confirm fitment.

Are 9/10-speed and 13/15/18-speed gearshift knobs interchangeable?

This collection lists separate 9/10-speed and 13/15/18-speed adapter options. Choose the configuration specified for your shifter rather than assuming they interchange. Check the exact product description before ordering.

Do I need an adapter for a thread-on gearshift knob?

Check the individual listing: many knobs in this collection are sold with an adapter, while adapters are also available separately. The separate M30×3.5 thread-on adapters list Eaton-Fuller applications and specific transmission speeds. Match both the thread specification and the stated application. Browse gearshift adapters.

What gearshift knob styles are available?

The collection includes Bristol and Charlotte styles, pool ball, dice, skull and pistol grip designs, plus knobs sold with LED adapters in several styles and finishes. Availability and transmission options vary by product. Browse classic and custom knobs or view knobs with LED adapters.

What should I check when buying a gearshift knob with an LED adapter?

Confirm the transmission application, finish, included adapter and the product’s electrical and installation requirements. Do not assume every illuminated option uses the same wiring or includes the same components. Use the exact listing to confirm what is supplied.

How do I choose a Peterbilt shift plate or shift plate cover?

Match the listed model and year, opening dimensions and any stated OEM reference to your existing plate. This collection includes wood, chrome and polished stainless steel options with different applications and opening sizes. Compare Peterbilt shift plates and covers.

Can I buy shifter accessories without replacing the complete knob?

Yes. This collection includes separately listed splitter buttons, range selector covers, lower gearshift knob covers, shafts and extensions. Check the part’s specific application before ordering. Shop buttons and covers or browse shafts and extensions.
