🔧 Technical Insights
To begin with, this isolator uses a flexible rubber material that absorbs shock and keeps vibrations from spreading. At the same time, the steel core gives it strength and keeps it in place under load.
Moreover, it is designed to resist changes in temperature, so it won’t crack or harden over time. Thanks to its precise shape, it lines up perfectly with other Cummins genuine parts. As a result, you get smooth engine function without any rattle or shake.
Finally, the isolator spreads stress evenly across mounting points. This means you avoid pressure build-up in one spot, which helps extend the life of your engine.
