XDP Performance Harmonic Dampener 01-05 GM 6.6L Duramax LB7/LLY
New injectors? Check! New Lift Pump? Check! An engine that shakes the whole truck? Also Check! The new upgrades to your truck maybe added more than just torque and horsepower. Protect your engine from damaging crankshaft harmonics with the XDP Performance Balancer Series Diesel Performance Harmonic Balancer XD722. Designed for 6.6L Duramax engines, this high-performance harmonic balancer delivers superior vibration control over the factory damper, making it an excellent upgrade for stock, towing, and high-horsepower applications.
Every diesel engine generates torsional vibrations as the crankshaft twists during combustion. Over time, these vibrations can lead to crankshaft fatigue, premature bearing wear, timing issues, and accessory drive problems. The XDP XD722 is engineered to absorb and dissipate these harmful forces, helping your Duramax run smoother while protecting critical internal components.
Built from CNC-machined billet steel and precision balanced for exceptional accuracy, the XD722 offers significantly greater durability than stock elastomer-style dampers. Its performance-focused design makes it ideal for trucks that tow heavy loads, run upgraded turbochargers, higher fueling, or are used in demanding street and competition environments.
