For such a cheap price and easy install, this little product is worth every penny in my experience. It increases your fuel back where it should be from the factory and holds up better with tuned engines. Most of the time you will see a 10psi increase with this blue spring kit. This keeps air out of the injectors and prolongs the life of them as well. A big benefit of the spring kit is to keep fuel pressure above 45psi at WOT. *Note that the max spec for fuel pressure is around 70-72psi. The spring will hold a more consistent pressure and will not drop off over time like the factory spring. There's really no downside to this kit and I believe its a must on any Ford 6.0L. No this upgrade does not hurt the pump.

Have a loose feeling front end? How about premature wear on parts? In this blog post we'll discuss some fixes for that and show you a recent front end done on a 2015 2500HD LML Duramax. Now yes the 01-19 GM truck suspension is very similar with just a few small differences so while this is done on a LML its the same concept for the older trucks as well.
