The "On-Board" Advantage for Duals

Rear duals carry the bulk of your load but are often prone to irregular wear and excessive heat build-up. Centramatic’s patented system uses centrifugal force to distribute high-density balancing media (durametal and synthetic fluid) to the exact point needed in real-time.

• Protect Your Investment: One pair of balancers handles four tires, wheels, hubs, and drums, making it a highly cost-effective upgrade.

• Massive Tire Savings: Increases tire life by 25%–50% by preventing the cupping and "scuffing" often seen on dually setups.

• Lower Operating Temps: Reduces tire heat by 8%–10%, which is critical for preventing blowouts when hauling heavy trailers or campers.

• Smoother Ride: Dramatically reduces the vibration and "hop" felt in the cab, whether the truck is empty or fully loaded.

Installation & Build Quality

• Maintenance-Free: A sealed, self-contained system with zero upkeep—no beads to clog valves or 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.
