Centramatic 600-648 Drive Axle Balancer Pair | 22.5-24.5" Wheel | 8-Lug 275mm BC

Centramatic Rear Drive Axle Wheel Balancers (Pair) – P/N 600-648

Fits: 22.5"–24.5" Wheels | 8-Hole Pattern | 275mm Bolt Circle

Eliminate the "rear-end bounce" and vibration that plagues heavy-duty dually chassis. The Centramatic 600-648 is precision-engineered for the 8-lug 275mm bolt circle common on modern medium and heavy-duty hub-pilot wheels. By stabilizing all four rear tires, wheels, hubs, and drums simultaneously, you'll experience a dramatic reduction in road shock and cabin noise.

The "On-Board" Advantage for Heavy-Duty Duals

Rear duals carry the bulk of your vehicle's weight and are often the hardest to keep balanced. Centramatic’s patented system uses centrifugal force to shift high-density balancing media (hardened durametal alloy and synthetic fluid) to the exact point of imbalance while you drive.

• Massive Tire Savings: Increases tire longevity by 25%–50%—a major cost saving for expensive 22.5" and 24.5" commercial-grade rubber.

• Protect Your Suspension: Dramatically reduces the high-frequency vibration that causes premature wear on shocks, bushings, and differential bearings.

• Lower Operating Temps: Reduces tire heat by 8%–10%, which is critical for preventing blowouts during long-distance hauling or high-heat summer operations.

• Self-Adjusting: Automatically compensates for mud, snow, or rocks stuck between your duals, and adjusts dynamically as the tires wear over time.

Installation & Build Quality

• Maintenance-Free: A sealed, self-contained system—no beads to clog valves and no lead weights to fall off.

• Easy Setup: No pre-balancing required. These mount directly between the dual wheels using your existing lugs.

• Speed Activated: Dynamically balances the entire assembly once you reach ~20–22 mph.

• Made in the USA: Built in Texas and backed by a 5-Year / Unlimited Mileage Warranty.
