Does your Silverado or Sierra feel like your driving a grain truck sometimes? With high mileage diesel trucks, sometimes we expect a less than smooth ride out of it but it doesn't have to be that way. Replace the worn factory balancer on your GM 6.6L Duramax with the XDP Premium Balancer Series Stock Replacement Harmonic Dampener XD709. Designed as a direct-fit OE-style replacement, the XD709 helps absorb harmful crankshaft vibrations that can lead to premature wear on critical engine components such as the crankshaft, main bearings, timing components, and accessory drive system.

The harmonic dampener/balancer, also known as a crankshaft vibration damper, plays a vital role in reducing torsional vibration created during combustion. Over time, the factory balancer's rubber isolator can deteriorate, crack, or separate, resulting in increased engine vibration, belt issues, and potential engine damage. The XDP XD709 is built with spheroidal graphite cast iron and features inserted and pressure-bonded rubber for exceptional durability and reliable vibration control under stock and moderately upgraded applications.

Whether you're restoring a daily-driven truck, towing heavy loads, or maintaining your Duramax for long-term reliability, the XD709 offers premium construction and OE-quality fitment you can trust. Product listings identify this balancer as a direct replacement for GM 6.6L Duramax engines.

When do I need to replace my harmonic balancer/dampener?

The dampener on your truck dampens (duh) torsional vibrations generated by the crankshaft, protecting internal engine components and improving smoothness. If your dampener is going out you will notice cracked rubber, wobbling at idle, unusual engine vibration, belt noise, and timing issues. Sometimes it can feel like the entire truck is going to fall apart but with this easy fix you can get it running smooth again!

Easy and convenient way to block off space!

Turned part of my basement into a dressing room. Ordered several of these and they worked out perfectly. I was able to separate the “guest room” area as well as our gym! Kept my space neat and private. And no assembly!
