The "On-Board" Advantage

Centramatic's patented technology features a permanently sealed ring filled with hardened durametal alloy and proprietary synthetic fluid. As you drive, centrifugal force automatically shifts this media to the exact point needed to bring the assembly into perfect equilibrium.

• Smoother Highway Ride: Virtually eliminates steering wheel shake and cab vibration at highway speeds, significantly reducing driver fatigue on long hauls.

• Maximum Tire Life: Proven to increase tire longevity by 25%–50%—essential for the high-load 19.5" commercial tires used on Ford Super Duty trucks.

• Lower Operating Temps: Keeps tires 8%–10% cooler, preserving the tire casing and reducing rolling resistance.

• Self-Adjusting: Automatically compensates for mud, snow, or rocks stuck in your tread, and adjusts as the tire wears over time.

Installation & Build Quality

• Maintenance-Free: A sealed, self-contained system with zero upkeep required—just install and drive.

• Easy Setup: No pre-balancing required. These mount directly between the hub and the wheel using your existing lugs.

• Speed Activated: The balancing media shifts into the correct position at ~20–22 mph, providing stability long before you reach highway speeds.

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