COATS 8308629 Medium Cone for 6401, 6450 Balancer

Best Medium Cone for Coats 6401 & 6450 Balancers

The medium cone from COATS (part #8308629) solves one of the most common challenges in heavy-duty wheel balancing: securing a consistent, precise mount on mid-range wheel sizes. With a 50mm center hole and a balancing range of 2.78 to 3.46 inches, this cone is purpose-built for Coats truck balancer models 6401 and 6450. Whether you're handling dually pickups, medium-duty fleet trucks, or stubborn wheels that never seem to center right, this cone gives you the repeatability and fit you can trust.

What Makes It Different?

Unlike generic cones or makeshift adapters, the 8308629 is an OEM component engineered to match the spindle and balancer tolerances of the Coats 6401 and 6450. That means tighter fit, faster setups, and less chance of vibration callbacks. It's made from rugged steel and built to last under daily use in commercial shops. If you're using a balancer all day, you need tooling that won't wobble or wear prematurely - and this one holds up.

• OEM fit ensures accurate, repeatable balancing
• Outlasts cheaper or universal cone alternatives

How It Performs in Real Shops

Technicians notice the difference as soon as this cone locks in. There's no guessing or play - it centers fast and stays stable. That means less time dialing in runs, fewer rebalance tickets, and better ride quality for the customer. It's especially handy when rotating between small- and large-cone wheels, giving you a reliable middle option that doesn’t compromise accuracy.

Ideal For:

• Truck tire shops balancing mid-size wheels
• Commercial fleets using Coats 6401 or 6450
• Shops looking to reduce comebacks from improper centering
