COATS 40mm Large Cone Adapter, 3.375" – 5.20"
COATS | 40mm Medium Cone

Best Medium Cone for 40mm Shaft Balancers
The medium cone from COATS is designed specifically for wheel balancers with a 40mm shaft, offering a secure clamping range between 2.12" and 3.13". Whether you’re working in an automotive shop or a tire service bay, this cone solves a common problem: poor centering and wheel slippage during balancing. It helps ensure that every wheel is locked in place evenly and spins true - which means fewer rebalances, faster service times, and happier customers.
Why This Medium Cone Outperforms Others
Unlike one-size-fits-all cones that often compromise precision, the COATS 40mm medium cone is engineered for an exact fit with 40mm shafts and mid-sized wheels. Its steel construction delivers long-term durability, and it consistently holds center without marring wheel hubs. You’ll notice the difference immediately in balance accuracy and machine repeatability.
- Dedicated design for 40mm shaft balancers - no sloppy fit or shim work
- Ideal for medium wheels, where large or small cones often struggle to center
How This Medium Cone Performs on the Job
In daily shop use, this cone makes balancing smoother and more reliable. It locks in solidly without play, helps reduce vibration callbacks, and speeds up workflow by eliminating guesswork. It’s also a great solution when your OEM cone set leaves gaps for common wheel sizes.
Ideal For:
- Shops balancing wheels in the 2.12"–3.13" bore range
- Techs using Coats wheel balancers with a 40mm shaft
