valve springs !!!

[DTanklage]

do any of you know the installed ht for the springs?

i have the diameters but need the ht when the valve is on the seat

i am hooked up with PSI

their springs are the only springs i can run in my bike with any kind of reliability

valve springs get glowing red hot at rpm (dont know if that holds true in our 3k rpm motors?) and at 13,500 rpm i have broken every one else's springs

i swear by psi springs (as do all the pro stock teams) and would love to get a set from them for my truck but i need to know the inst ht and seat pressure

Now the #60er's are supposedly good for 4000, right?

At least I've read the threads about the new trucks going to 4000 on stock valvetrain; I guess that #60er's are still stock, right?

There doesn't seem to be much in the way of a popular increase after the 60's. I know that KTA runs some crazy valve springs, but I don't know if he's divulged any information on those yet.

Haisley Machine or somebody's probably got whatever the 5000 RPM sledpullers use.

thanks BC

i have been asking and asking and to be honest i doubt that there is more than a hand full of guys on these forums that know

and they either havent been looking on here or dont want to say

its only money, i ordered a set of them so i can see for myself

tell ya this much, those cummins springs, with the different dia top to bottom, aint all that...

thanks again for the link

They seem to be good for the 4000 RPM that most are stuck at.

I'm assuming that you mean that you bought some 60 PSI'ers?
