Coats 113309C OEM Pressure Drum for Alloy Wheel Balancing

Big alloy wheels off a luxury sedan, SUV, or performance car won't sit right in a standard drum. You get wobble, inconsistent centering, and balance numbers you can't trust when a customer's paying for precision. The Coats 113309C OEM Pressure Drum fixes that with an 8.375 inch capacity built for larger alloy wheels and a 40mm inner diameter that locks onto your balancer spindle without play. That exact fit eliminates the misalignment that throws off repeatable measurements. It's built on Coats' Alu-Cup design, which distributes pressure across the wheel differently than a generic drum, so you get solid clamping without marking up an expensive finish.

Machined from alloy that holds its tolerances after years of daily use, this drum won't loosen up and start throwing off your numbers the way cheaper stock drums do over time. It's built for shops running a steady mix of luxury, SUV, and performance wheels, from dealership service bays to high-volume tire shops needing repeatable accuracy on every alloy set that comes through the door. We stock genuine Coats balancer accessories like this one, so replacing a worn pressure drum doesn't mean waiting weeks on backorder.
