Centramatic Wheel Balancers. 19.5 inch 10-hole pattern Ford Rear wheel balancers. These are for 1999 and Up Ford Trucks for the Rear or "Drive Axle". Set of 2.
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.
Your tires will run smoother, quieter, and cooler, with much longer tread life.
Eliminates "cupping" of aggressive off-road M/S tires.
