Has your GM truck not been running right these past thousand miles? 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 Balancer XD708. Designed as a direct-fit OE-style replacement, the XD708 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 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 XD708 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 XD708 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 right again!

Color: Christmas Green, Size: Large, Color: Christmas Green, Size: Large
We were quite amazed with the fit and quality of this jacket. It was used for one night of prom and looked great! Each of my son's closest friends wore different colors of the same jacket and they all looked great and coordinated with their dates!

Sophisticated
Color: Wine Red, Size: Large
This blazer exceeded my expectations! The floral paisley design looks stylish and elegant without being over the top. The fit was true to size, and the shawl lapel gives it a classy, high-end look. The fabric is thick, but the texture of it is soft. I wore it to a formal event and received tons of compliments all night. Great choice for prom, weddings, or dinner parties at an affordable price.

Sized Up, Still great!
My son typically requires a 3x TALL, so I sized up one (4x) but had it gone to a 5x that might have been even better. For reference he is 6 foot tall, 300 lbs, and very broad shouldered (think lineman 🤣) However, the quality and print were so great! He opted for a chain instead of the bowtie because he did a bow tie last year, but that was decent as well. For the price, this is a GREAT buy.
