Why Bloomer Owners Choose Centramatic

Large livestock and equipment trailers are prone to significant vibration, especially when running 19.5" tires. Centramatic’s patented technology uses centrifugal force to move high-density media (hardened durametal alloy and synthetic fluid) to the exact point of imbalance while you drive.

• Protect Your Livestock: Dramatically reduces the high-frequency floor vibration that leads to animal fatigue and stress during transport.

• Save Your Tires: Increases tire life by 25%–50% by preventing the cupping and irregular wear common on heavy-duty trailer axles.

• Lower Operating Temps: Reduces tire heat by 8%–10%, providing an extra layer of safety against blowouts during long hauls in extreme heat.

• Dynamic Balancing: Unlike static lead weights, these adjust in real-time to compensate for mud, ice, or uneven tire wear.

Installation & Durability

• Maintenance-Free: A completely sealed system with no moving parts to service—just bolt them on and go.

• Easy Setup: 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 (wheel, tire, hub, and drum) at ~20–22 mph.

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