If you’re looking to upgrade the engine in your diesel truck, a good harmonic balancer is worth every penny. The harmonic balancer is designed to literally keep everything balanced. Its function is to provide durability by controlling the destructive torsional vibration these engines create. That being said, the popularity of the L5p engine in the late model Duramax-powered GM trucks is on the rise and Fluidampr is capitalizing.

Fluidampr just announced that they have released not one but two performance diesel dampers for the L5P engines. If you or someone you know is in the market to upgrade their L5P, here you.” We’re excited to bring you this new product release,” remarks project lead, Nick Orefice. “Fluidampr has extensive experience with the Duramax L5P engine. Variations of this damper have already seen widespread use by the United States military in their latest high performance light tactical vehicles. Now it’s ready for all out street performance and professional competition use.”
