Ensure the smoothest possible ride for your luxury motorhome or bus with the Centramatic 600-690. Unlike traditional lead weights that only balance the tire once, this system provides continuous, dynamic balancing for the entire wheel assembly—tire, wheel, hub, and rotor—as you drive. The polished stainless steel finish ensures that your balancers look as good as they perform, resisting rust and corrosion for the life of the vehicle.

The "On-Board" Advantage for Luxury Coaches

Centramatic's patented technology utilizes a permanently sealed ring filled with hardened durametal alloy and proprietary synthetic fluid. Centrifugal force automatically shifts this media to the exact point needed to bring the entire wheel assembly into perfect equilibrium.

• Supreme Driver & Passenger Comfort: Virtually eliminates steering wheel "shimmy" and road vibration, providing the quiet, stable ride expected in a high-end coach.

• Protect Your High-End Rims: The polished stainless steel construction complements aluminum wheels and will not dull or rust over time.

• Maximum Tire Life: Proven to increase tire longevity by 25%–50% by preventing the cupping and irregular wear patterns common on heavy steer axles.

• Lower Operating Temps: Reduces tire heat by 8%–10%, which is critical for safety and tire integrity during long-distance travel in high heat.

Rugged & Maintenance-Free

• Zero Upkeep: A sealed, self-contained system—no beads to clog valves and no lead weights to fall off.

• Simple Installation: No pre-balancing required. These mount directly behind the wheel on the hub using your existing lugs.

• Speed Activated: The system begins balancing the entire assembly once you reach highway speeds (~20–22 mph).

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