Control Harmonics Before They Control Your Build

When you're stacking horsepower in your 2011 to 2016 Duramax LML, engine vibration isn't just a minor annoyance—it can become a real threat to long-term reliability. That's where the PPE Xtreme Damper steps in. Designed as a direct replacement for the factory unit, this damper delivers the kind of performance and protection your crankshaft needs under serious load. It works by reducing torsional vibrations that build up as RPMs climb, helping to prevent damage caused by prolonged stress and harmonic imbalance. Whether you're daily driving a high-output tune or pulling heavy loads with upgraded internals, this damper plays a critical role in keeping your engine running smooth and healthy.

Engineered Strength in a Three-Piece Design

PPE didn't just beef up the mass and call it a day. This 16.1-pound damper uses a smart three-piece design made up of a hub, outer ring, and internal counterweights, all working together to deliver consistent, balanced dampening across the entire rev range. The added weight helps absorb more vibration energy without overloading the crankshaft, especially useful when you're pushing far beyond stock limits. For added convenience, PPE includes laser-etched timing degree marks that are easy to read during installs or adjustments. This damper isn't just for racers or extreme builds either—it's a solid upgrade for anyone who values long-term engine stability and wants to keep their truck running strong mile after mile.
