The Coats 8308642 is an OEM replacement pressure drum designed for use with the Coats 6401 and 6450 HD wheel balancers. Constructed from heavy-duty poly material, this precision component creates a tighter seal against the rim and applies more even force across the tire during the balancing process. The result is a notably more accurate balance, particularly when working with alloy wheels that demand tighter tolerances. Built to OEM specifications by Hennessy Industries, this pressure drum delivers the fit and performance required for professional tire service environments.
