COATS 8308642 Pressure Drum for 6401/6450 HD Balancer Overview

Alloy wheels punish a loose seal. Any play between the tire and drum during balancing shows up as an inaccurate reading, and you end up rebalancing wheels that should have been right the first time. Worn factory drums lose that tight fit over time, and once they do, every alloy wheel that comes through your bay is a coin flip. The COATS 8308642 Pressure Drum fixes that by creating a tighter seal and applying even force across the tire, so your 6401 or 6450 HD balancer reads true instead of guessing.

Built from high-strength composite, this OEM drum matches your Coats balancer exactly, so there's no fitting or adjusting to work through. Pair it with the back cone spring, part number 8303639, and you get an even tighter setup for the toughest alloy wheels passing through your bay. Keep both parts on hand and precision balancing stays consistent job after job instead of depending on which drum happens to still hold a seal. It's a small swap that saves you from second-guessing every alloy wheel reading, and you can reorder it whenever your current drum starts to wear.
