CYELARS Tire Changer Duck Head Replacement 2-Pack — Black ABS Wing-Style, Rim-Safe Demount Heads for Workshop Machines

CYELARS Duck Head 4-120129B is a wing-style ABS demount head designed to replace metal duck heads on compatible tire changers, protecting rims while keeping the tire centered for faster, safer mounting and demounting.

This two-piece replacement set fits a wide range of workshop tire machines and is made from resilient ABS plastic to minimize rim scratching, chipping, and metal-on-metal contact. It’s shaped to hold the tire in the wheel drop center, preserving the ideal installation angle so you don’t need extra adapters. The part replaces several OEM numbers and is intended for professional shops and serious DIYers who want a durable, rim-safe alternative to metal heads.

How does the ABS duck head protect wheels and tires?

Unlike metal demount heads, the CYELARS unit uses high-grade ABS to reduce abrasion and impact on alloy and finished rims. The plastic surface cushions contact points and eliminates metal-to-metal scraping, lowering the chance of cosmetic damage during routine service.

• ABS construction resists scratches, dents, and cuts to wheel finishes
• Rounded wing-style profile prevents sharp contact edges
• Plastic bead contact avoids scoring on alloy rims
• Durable formulation resists deformation under normal shop loads

Will this duck head improve workflow in a busy shop?

Yes. The mount-demount geometry is designed to keep the tire centered in the wheel drop, so the bead stays at an optimal angle for faster, repeatable mounting and demounting. That reduces the need for auxiliary adapters and cuts cycle time when processing many wheels.

• Maintains ideal tire installation angle without extra parts
• Simplifies repetitive tasks for faster throughput
• Sold as a 2-pack so you can swap or keep a spare ready
• Lightweight ABS makes handling and positioning easier for technicians

How durable and serviceable is the CYELARS duck head?

The head is molded from tough ABS engineered for shop use. While not as hard as metal, the plastic resists everyday impacts and can be replaced quickly at a low cost when worn. Keep it clean from grit and inspect for deep gouges that could contact rims.

• High-quality ABS resists standard shop wear and impact
• Low-cost replacement compared with machining or OEM metal parts
• Easy to remove and re-install for quick service
• Plastic design decreases long-term wheel finish repair needs

Who this is for: technicians, tire shop owners, fleet maintenance crews, and advanced DIYers who use compatible tire changer models and want a rim-friendly, cost-effective alternative to metal duck heads. If you prioritize protecting alloy and painted wheels while keeping tire-change cycles efficient, this CYELARS 2-pack offers an immediate, simple upgrade to your equipment setup.
