Protect Your Power and Keep It Smooth

If you're running big power in your 2006 to 2010 Duramax, there’s more to think about than just fuel and boost. Harmonic vibrations in the crankshaft are one of those hidden issues that can sneak up and cause serious engine damage if left unchecked. The PPE Xtreme Damper is built to prevent exactly that. It’s a direct-fit replacement for the stock unit, but with a far more robust design that’s tuned for the needs of high-performance and heavily modified trucks. Whether you're daily driving a tuned build or making serious power under load, this damper helps reduce the internal stress that builds up at higher RPMs, keeping your crankshaft stable and your power delivery smooth.

Balanced Design for High-Stress Builds

This damper isn’t just heavier—it’s smarter. Weighing in at 16.1 pounds, it uses a three-piece construction that includes a central hub, outer ring, and counterweights. Each piece is engineered to absorb and neutralize vibration from different areas of the crankshaft, giving you balanced dampening across the full RPM range. That added weight isn't a burden—it’s what keeps your rotating assembly from shaking itself apart under pressure. PPE even includes laser-etched timing marks on the face, making it easy to read during tuning or engine work. It’s a solid investment for any truck that’s built to do more than just cruise, giving you peace of mind every time you hit the throttle.
