Centramatic Wheel Balancers. 22.5 inch Class C Motorhome/Truck wheel balancers. These are for 10-bolt pattern, 11.25 inch wheels for the Front Steering AxleSet of 2, for a vehicle with large brakes. This special application balancer is made to fit vehicles with big brake drums - 16" and/or brake drums with sprues. If used on 22.5" wheels - must be aluminum wheels only for this part number! DO NOT use with 22.5" steel wheels! Can be used with 24.5" steel or aluminum wheels. DO NOT install if valve stem contacts balancer. Bend valve stem or replace if necessary. Your tires will run smoother, quieter, and cooler, with much longer tread life.
Centramatic "ON-BOARD" Balancers mount to the vehicle, (between the wheel and hub on the front and between the wheels on the dual rear). The balancer dynamically balances your tire/wheel by using centrifugal force and deflection from rotation to automatically distribute free moving weights (durametal and synthetic dampening fluid) sealed inside the outer rim of the balancer. The wheel, tire, hub, drum/rotor assembly is continuously balanced under all driving conditions, even with rocks in the tread or mud, snow and ice stuck to the wheels.
