Installed a Sinister Diesel blue spring kit on my 04 Ford F-350 6.0l. I was quoted $90.00 plus parts but saw other videos and decided to tackle it myself. Huge difference in the way the truck feels now and better power when it's cold. I noticed better acceleration when cold and of course no more leaky fuel filter. Definitely something you can tackler yourself. I got the kit from Sinister directly and was around $65.00.
