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 XD723. 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 XD723 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 XD723 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.

Comfortable and stylish
This has been wonderful. My son is a game show host and has to wear a blazer to work on game days. He throws this in the back of his car when he’s done and it’s went through a lot and still holds its shape. The colors look great and it’s comfortable. He says it doesn’t feel heavy on and is easy to take care of.

What a great fun purchase!
How fun this jacket was!! Fit true to size. (XL pictured). Made well. Sequins help up well-they didn’t fall off. Bright color. Nice covered buttons with extras! Would definitely buy again. Got tons of compliments at event we attended. Paired great with dress shirt, bow tie, black jeans and gold light up shoes we also found on Amazon. Price point was great compared to others. Husband wears XL and this was very comfortable when sitting and also when buttoned standing up.

Jazzy!
Looked fine and fit just right. Sequins do rub the neck a little, if the shirt collar isn't high enough. Really got a jazzy feel to it.

Fit great, good price, and fast shipping for a last minute NYE dinner
Let me start by saying that I had very low expectations, all I truly cared about was getting something “blingy” as fast as possible for a last minute New Years Eve dinner. I was impressed by the speed of arrival, price & floored by the quality. Now of course, this is NOT a tailored $300 jacket, but it was great for our evening. Did not shed any sequins, no problems with wrinkles, and didn’t have any weird smells. My husband said it was comfortable, and he plans to wear it again should the need arise.
