The "On-Board" Advantage

Centramatic's patented technology features a sealed ring filled with hardened durametal alloy and proprietary synthetic fluid. As your wheels spin, this media automatically shifts to counteract heavy spots in the tire and wheel assembly.

• Smoother Dually Ride: Dramatically reduces the "pounding" and vibration common in unloaded or heavily loaded dually trucks.

• Maximum Tire Life: Proven to increase tire longevity by 25%–50%—a massive saving for 6-tire setups.

• Lower Operating Temps: Keeps tires 8%–10% cooler, which is critical for preventing sidewall failure and preserving tire casings.

• Continuous Adjustment: Automatically compensates for mud, snow, or debris that can get trapped between dual wheels.

Installation & Durability

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

• Maintenance-Free: A sealed, self-contained system with zero upkeep required.

• Speed Activated: The balancing media shifts into the correct position at ~20–22 mph.

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