Ok just did a search and I couldn't find what i was looking for, maybe i was just searching for the wrong thing cause i know 60# vlave springs have been covered before.

SOOOO, Here goes. I am planning on adding the Hd valve springs so i can avoid a piston hitting a valve and then i would like to add the 4k spring to my 3k now. what i want to know is dose anyone have a part number for me so i can get them from the Implament store here and also do i need to upgrade the retainers when i do it.?

no need to upgrade retainers, i got my hd springs from piers diesel. IIRC it was $120 for all 12

When do we need to upgrade to these?

Honestly, I think that should be up on the list with guages. But it depends on how u use or how hard u run the truck

How hard is it to install these? Special tools? Is there a write up somewhere on installing these?
