Centramatic Rear Drive Axle Wheel Balancers (Pair) – P/N 600-628

Fits: 19.5" Wheels | 8-Hole Pattern | 275mm Bolt Circle

Eliminate the "rear-end bounce" and vibration that plagues heavy-duty dually chassis. The Centramatic 600-628 is precision-engineered for the 275mm bolt circle common on late-model 19.5" wheel applications, stabilizing all four rear tires, wheels, hubs, and drums simultaneously.

The "On-Board" Advantage for Heavy Loads

Dually rear ends carry massive weight, making them prone to irregular wear and excessive heat build-up. 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 19.5" commercial-grade tires.

• Lower Operating Temps: Reduces tire heat by 8%–10%, which is critical for preventing blowouts during heavy towing or hauling in high heat.

• Protect Your Components: Dramatically reduces road shock and vibration, protecting your shocks, bearings, and the truck's overall structural integrity.

• Self-Adjusting: Automatically compensates for mud, snow, or rocks stuck between your duals, and adjusts 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 assembly once you reach ~20–22 mph.

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