The Centramatic 300-356 is a premium "on-board" balancing solution engineered for Jeep and light-duty trucks equipped with a 6-lug bolt pattern. As Jeep moved to 6-lug configurations on newer models like the Wagoneer, and with many off-roaders utilizing 6-lug conversions, this system provides a permanent, dynamic solution to eliminate the steering wheel "shimmy" often caused by oversized tires.
Fits: 16"–20" Wheels | 6-Hole Pattern | 5.5" Bolt Circle
Eliminate highway vibration and protect your suspension with the Centramatic 300-356. These balancers are precision-designed for the common 6-hole, 5.5" bolt circle, providing a dynamic solution that stabilizes the entire wheel assembly—tire, wheel, hub, and rotor—in real-time as you drive.

⚠️ Fitment Note: Due to variances between vehicle models and aftermarket wheel configurations, we may not be able to fit all applications. Please verify clearance before installation.
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 bring the assembly into perfect equilibrium.
Balance Oversized Tires: Essential for 33" and larger tires that are notoriously difficult to balance with traditional lead weights.
Trail-to-Highway Ready: Automatically compensates for mud, snow, or rocks stuck in your tread. The system re-balances itself dynamically the moment you hit highway speeds.
Maximum Tire Life: Proven to increase tire longevity by 25%–50%—a massive cost saving for high-end All-Terrain or Mud-Terrain tires.
Protect Your Components: Dramatically reduces the vibration and road shock that can cause premature wear on wheel bearings, shocks, and steering linkages.
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 at the tire shop. These mount directly behind the wheel on the hub using your existing lugs.
Speed Activated: The balancing media shifts into the correct position at ~20–22 mph, providing stability long before you reach highway speeds.
Made in the USA: Built in Texas and backed by a 5-Year / Unlimited Mileage Warranty.
