The Centramatic 400-406 is a specialized "on-board" balancing solution specifically designed for P-30 chassis vehicles and other light-duty trucks or motorhomes running 19.5-inch wheels. 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 drum—as you drive.

Real-Time Balancing: Centrifugal force automatically shifts the balancing media to the exact opposite of heavy spots, mud, or snow buildup.
Lower Tire Temps: Reduces operating temperatures by 8%–10%, which is critical for preserving tire casings on heavier motorhomes and trucks.
Extended Tire Life: Proven to increase tire longevity by 25%–50% by eliminating the vibrations that cause irregular wear and cupping.
Enhanced Comfort: Dramatically reduces steering wheel "shimmy" and cab vibration, leading to a much smoother ride and less driver fatigue.
Maintenance-Free: A sealed, self-contained system with zero upkeep required—just install and drive.
Easy Setup: No pre-balancing needed at the tire shop. Simply mount the balancers between the hub and the wheel using your existing lugs.
Speed Activated: Corrects imbalances dynamically once you reach ~20–22 mph.
Quality Assurance: Proudly Made in the USA (Texas) and backed by a 5-Year / Unlimited Mileage Warranty.
