CYELARS Tyre Changer Duck Head replacement 2-pack — Wing-style Black ABS, protects wheels and speeds mounting

CYELARS Duck Head 4-120129B is a wing-style, black ABS plastic mount/demount head designed to protect wheels while speeding up tire changing on compatible tire machines (2 pack).

These replacement duck heads are manufactured from durable ABS to reduce scratching, denting and metal-to-rim contact when removing or installing tires. They fit a wide range of popular tire changer models and replace common OEM part numbers so you can restore functionality without buying a new machine. The wing-style profile keeps the tire centered and holds the bead at an optimal angle, simplifying the job for shop technicians and mobile mechanics.

How does the wing-style duck head improve workflow at the tire bay?

The wing-shaped design maintains the tire in the center of the drop zone and keeps the bead at a consistent installation angle. That reduces manual adjustments and the need for extra accessories, letting a single operator finish jobs faster and with fewer rim contacts.

• Centring action holds tire steady during demount and mount cycles.
• Maintains optimal angle for easier bead seating and removal.
• Reduces time spent repositioning the wheel or adding protective tools.

Why choose ABS plastic duck heads instead of metal ones?

ABS plastic provides a high-toughness surface that is gentle on alloy and painted rims while resisting scratches and cuts from metal demount heads. Using plastic duck beads prevents direct metal-to-wheel contact, lowering the risk of cosmetic damage and saving time on rim touch-ups.

• ABS resists dents and surface abrasions compared with metal alternatives.
• Plastic-to-wheel contact protects delicate finishes on alloy and chrome rims.
• Lightweight construction eases installation and minimizes tool wear.

How do I install and maintain these replacement duck heads?

Installation is straightforward: remove the worn head from the machine’s mount and secure the CYELARS duck head in its place following your machine’s service directions. Maintenance is minimal—keep them clean, inspect for deep cuts, and replace as needed to maintain safe, damage-free operation.

• Follow your tire changer manual for proper removal and torque specs.
• Wipe clean after heavy use; inspect for cracks or severe wear regularly.
• Replace the head if plastic is deeply gouged or deformed to avoid rim damage.

Who is this for: professional tire technicians, independent repair shops, and mobile installers who need a reliable, rim-friendly replacement mount/demount head for common tire changers. It’s also suitable for owners of older or mixed-brand machines seeking a direct-fit, cost-effective spare that reduces wheel damage while speeding up routine tire service.
