Centramatic 370-800 Hummer H1 Balancer Set (4) | 16.5" Wheel | 8-Lug 6.5" BC

The Centramatic 370-800 is a specialized "on-board" balancing solution engineered specifically for the unique requirements of the Hummer H1. Because the H1 often runs heavy, oversized tires (like the classic 37" military tires) that are notoriously difficult to balance with traditional weights, this system provides a permanent, self-adjusting solution for extreme terrain and highway speeds.

The "On-Board" Advantage for the H1

Centramatic's patented technology features a permanently sealed ring filled with hardened durametal alloy and proprietary synthetic fluid. As the wheel spins, centrifugal force automatically shifts this media to the exact point needed to counteract heavy spots.

• Conquer Huge Tires: Specifically effective for 37" and larger tires that traditional lead weights often fail to balance properly.

• Protect Your Geared Hubs: Dramatically reduces the vibration and road shock that can cause premature wear on the H1's complex geared hub assembly.

• Off-Road Ready: Automatically compensates for mud, snow, or rocks stuck in your tread, and re-balances itself the moment you hit the pavement.

• Maximum Tire Life: Proven to increase tire longevity by 25%–50%—a significant saving on expensive specialty tires.

• Lower Operating Temps: Keeps tires 8%–10% cooler, preserving the tire casing during long-distance travel.

Installation & Build Quality

• Maintenance-Free: A sealed, self-contained system with zero upkeep required—no beads to clog valves and no weights to fly off on the trail.

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

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