PSI Valve Springs & mopar performance hyd cam

the guides have been machined for the inner of a double spring, so it looks.

stay away from rusted springs...they will break sooner than later, the pitting is a sure tell wether or not to use them.imo

A mild surface dust of rust is not bad, but surface damage/pitting is.


you're missing some springs, so....just buy another set for $80-$90 of the comp springs.,,,you gotta remember the springs cycle and loose an average of 7 psi after a lil heat cycling.........the last set of mopar '847 springs I used lost 12psi, had to shim them up.
