High-Performance Crankshaft Dampers for Class 8 and Commercial Diesel Engines
KLM Performance offers Vibratech Viscous Crankshaft Dampers designed for heavy-duty diesel engines, including:
These American-made viscous dampers provide superior vibration control, durability, and protection across all RPM ranges and power levels, outperforming traditional OEM elastomer harmonic balancers.
Why Upgrade to a Vibratech Performance Crankshaft Damper?
Prevent Engine Damage from Torsional Vibrations
Torsional vibrations occur as the crankshaft twists and rebounds due to combustion torque. Without proper damping, these vibrations can cause:
- Crankshaft cracks or failure
- Excessive bearing wear
- Gear wear and failure
- Broken accessory drives
- Belt slapping or throwing
- Increased driver fatigue
Upgrading to a Fluidampr Viscous Crankshaft Damper ensures real-time torsional vibration control, extending engine life and reducing costly repairs.
Signs Your OEM Harmonic Balancer is Failing
If you notice any of the following, it is time to replace your crankshaft damper:
- Cracked or bulging rubber on the harmonic balancer
- Outer ring separating from the hub
- Increased in-cab vibrations
- Visible wobble of the damper during operation
- Serpentine belt slipping or misalignment
A worn-out OEM rubber damper loses effectiveness over time, exposing critical engine components to excessive vibration damage.
Vibratech Viscous Crankshaft Dampers - Key Benefits
- Designed for stock and high-performance diesel engines
- Lifetime durability – no need for tuning or rebuilding
- SFI 18.1 certified for racing applications
- Real-time vibration control at all power levels
- Reduces main bearing wear and timing gear stress
- Protects against oil pump failure and valve train damage
- Prolongs engine life and improves fuel efficiency
How Often Should You Replace a Diesel Engine Crankshaft Damper?
Heavy-duty diesel engines require crankshaft damper replacement every:
- 500,000 miles
- 15,000 engine hours
Over time, the OEM damper's silicone deteriorates, reducing its ability to absorb vibrations. Delaying replacement can result in catastrophic engine failure and costly repairs.
Warning Signs Your Diesel Engine Damper Needs Replacement
- Excessive bearing and gear wear
- Loosening of bolts and fasteners
- Noticeable engine vibrations and noise
- Decreased horsepower and fuel efficiency
- Fluid leakage from the damper housing
A failing harmonic balancer or crankshaft damper is one of the most overlooked causes of engine rebuilds and downtime. Prevent costly failures by replacing your damper at regular intervals.
What Makes Vibratech Viscous Dampers Superior?
Vibratech TVD is the original inventor of viscous damper technology and has been manufacturing precision crankshaft dampers in the USA since 1946. Their dampers are built using:
- ISO 9001 certified CNC machining and quality control
- High-viscosity silicone fluid for maximum damping
- Sealed, leak-proof, laser-welded housing
- Precision computer balancing for optimal performance
Unlike traditional rubber dampers that degrade over time, Vibratech Viscous Dampers continuously adapt to changing engine loads, delivering unmatched torsional vibration control across all RPM ranges.
