Has anyone ever tried a set of these? They are $237.50 on their website. Here is a picture.

5000 RPM springs. St. Joe Diesel is a pretty reputable place. I've never tried 5K springs in my pickup, but my buddy swears that they rev smoother than a 4K kit because of only 2 springs instead of 3 there's no transition.
 
Looks like CDS 5k's and last time i checked they were 175 from CDS and they make them in house.
 
No, but I may try a set sometime. St. Joe does all of my pumps.
 
Same pic is on dynamite diesels site. Those are CDS springs just get them from the source CDS.

I might even have an extra set laying around can bring them to TS if you want them.

just curious what guy at st joe diesel does your pumps i was told never get a turbo from them since they just blow up after one pull but did hear they had good pumps and they have a guy that is amazing with duramaxs ive dynoed down there and had to tell the guy how to dyno since he had never ran a manual on it before but we did like 12 pulls for $60 and they are very nice group of guys
 
I like to try a set of either , these tweaked 4k are way to touchy
 
I believe Tim does the Duramax tuning, but Aaron builds the p-pumps and he does a pretty thorough job. I'll try to call his cell tomarrow and ask about the springs.
