COATS 8308630 Large Cone Overview

You're mounting a truck wheel on your 6401 or 6450 balancer and the cone in your kit doesn't seat right on the center bore. Wrong fit means a wobbly spin, a bad reading, and a wheel that comes back off the vehicle with a shake. The COATS 8308630 large cone closes that gap. It's built specifically for the Coats 6401 and 6450 truck balancers, with a 50mm center hole and a balancing range of 2.98 to 5.06 inches.

This large cone covers the middle of the truck-wheel range, so it slots in right between the 8308629 medium cone and the 8308631 truck cone. Machined from high-quality steel, it holds the wheel true through the spin cycle and takes the daily abuse of a busy shop without deforming. When a cone is off even slightly, every balance job after it inherits the error. Get the right one and your readings stay honest.

We stock the full Coats cone lineup for these balancers, so if your bay handles everything from light-truck to heavy commercial tires, you can match the cone to the bore instead of forcing a compromise fit.

Frequently Asked Questions

Which balancers does this cone fit?

The 8308630 large cone is made for the Coats truck balancer models 6401 and 6450. It uses a 50mm center hole to seat on the shaft, so it won't fit balancers with a different shaft size.

What wheel bore range does this cone cover?

It handles a balancing range of 2.98 to 5.06 inches. That covers the mid-section of truck-wheel bores, sitting between the 8308629 medium cone and the 8308631 truck cone.

How do I know if I need the large cone or a different size?

Match the cone to your wheel's center bore. If your bore falls between 2.98 and 5.06 inches, this is the one. Smaller bores use the 8308628 or 8308629, and larger truck bores from 4.52 to 6.95 inches use the 8308631.
