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 entire wheel assembly into balance.

• Smoother Ride: Virtually eliminates steering wheel shake and cab vibration at highway speeds.

• Maximum Tire Life: Proven to increase tire longevity by 25%–50%—essential for expensive heavy-duty or all-terrain tires.

• 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.

• Easy Setup: No pre-balancing needed. These mount directly behind the wheel on the hub using your existing lugs.

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

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