does anyone here use them, i know they are big with sledpullers, but wanted to know what your results were, and if you know the spring rates from set psi to abou . 395-. 400 lift thanks

They work great but EEP's kit comes with more than just valve springs.

If you set a set of EEP springs next to a stock set you will see the difference. If you put the stock set on a bench after about 40,000 miles many of the spring will be different lengths. I did notice a performance gain and the truck smoked more because the valve are all seating I think.

awesome, any idea how much psi they have at various lifts or hights, they reccomend the titanium retainers cause they dont trust the stock valve components, any other thoughts? thanks
