Best Value
This is the best value in the 7.3L world. Honest pricing and fast shipping. Had tracking in 5 hours after placing my order. Better pedal response, and it idles smoother as well.

7.3 Spring Kit
I changed this out and I cant say that I had a huge surge in power, but I can tell a bit of a difference. This needed to be done vs waiting and its pretty inexpensive. The customer service is really GREAT! If I have a question they get back to me quickly. I am the stage of life now that the customer service is just as important as the product and the price. Really appreciate Riffraff Diesel! Thanks Clay!!!

Springs
I couldn't tell the difference between the silver and gold springs. Either the difference was very subtle or I got 2 silver springs. I took a guess at which I thought was gold and put it in.
