YIUIY Round Ball Shift Knob — Pure White Universal Gear Shift Knob for 5/6-Speed with Adapters, Marble-Style Acrylic

Upgrade your vehicle's shifter with a minimal, marble-style ball that combines an aluminum-alloy core and tough acrylic finish for long-lasting wear and a smooth hand-feel. The clean white finish adds a refined, understated look to interiors while the included adapter set makes swapping the knob straightforward in most cars with removable stick shifters.

Will this shift knob fit my car?

The YIUIY round ball knob is designed to suit many transmissions without altering the shifter. It comes pre-threaded M12×1.25 and includes adapter sleeves to match common thread sizes so you can install it quickly on compatible vehicles.

• Included thread: M12×1.25 (installed)
• Adapters supplied: M8×1.25, M10×1.25, M10×1.5
• Compatible with most removable stick-type shifters
• Not suitable for shifters requiring additional locking buttons or special upshift mechanisms

What is the knob made of and how does it feel?

This gear knob pairs a lightweight aluminum alloy interior with a durable acrylic outer shell that mimics marble. The result is a solid, comfortable grab that resists fading and surface wear from daily use.

• Core: aluminum alloy for strength and weight balance
• Exterior: high-quality acrylic with marble-style finish
• Surface resists discoloration and keeps a smooth tactile feel
• Pure white styling offers a calm, elegant cabin accent

How easy is installation and what are the exact dimensions?

Installation is intended to be a direct replacement without cutting or special tools on most vehicles. The knob’s outer diameter and supplied adapters cover common aftermarket thread sizes to minimize extra parts or modifications.

• Outer diameter (OD): 5.4 cm (2.13") for ergonomic grip
• Pre-installed thread: M12×1.25
• Adapter set: M8×1.25, M10×1.25, M10×1.5 included
• Designed for simple hand-tight or basic-tool installation

Are there any installation limits or special considerations?

While the knob fits many manual and automatic cars, it only works with shifters that remove from the shaft. Some transmissions require a button, collar, or special action to engage reverse or shift—those systems may not be compatible without further modification.

• Not for permanently fixed shifter levers
• Not compatible if reverse requires separate locking or button action
• Confirm your vehicle’s thread and removal method before ordering
• Adapters cover most common aftermarket thread standards

Who is this for? Drivers who want a clean, minimal upgrade to their cabin without complicated installation will appreciate the YIUIY pure white round ball shift knob. It suits owners of many 5-speed and 6-speed cars who prefer a neutral, elegant look and a solid, durable feel from their shifter knob; however, verify your vehicle's removable-shifter design and thread size before purchase.
